Abstract:
This research studied the feasibility of using natural fibers extracted from natural wastes as a thermal-insulating material lined in a Kraft paper box packaging. The natural fibers were extracted from natural waste of rice straws using NaOH solutions. The extracted fibers were then formed as a porous thermal-insulating pad by a spray lay-up method using natural rubbers as binders. The thermal conductivities, specific heat capacities and temperature-rise time of the natural fiber insulation and other thermal-insulating materials including polystyrene foam, a polyethylene foam, and a glass fiber insulation were studied and compared. The glass fiber insulation showed the highest thermal conductivity, while the thermal conductivities of the other studied insulating materials were found to be similar. Moreover, the polymeric and natural-fiber insulations show better temperature-rise resistance than the glass fiber insulation. The temperature rises for different insulating materials were estimated using the analytical analysis of heat transfer. The calculated temperature-rise times were compared with the empirical results; both results are in the same order of magnitude. Consequently, a Kraft paper box lined with natural-fiber pads was constructed and compared with a Kraft paper box (without insulation lining) and a polystyrene box of equal sizes. The boxes were packed with an equal amount of ice and left under room temperature for 24 hours. The results show that, after 24 hours, the temperatures inside the natural-fiber lined box and the polystyrene box were contained below 15 °C, while the temperature inside the Kraft paper box increase to room temperature only after 16 hours. The observation shows that a natural fiber pad can potentially be used as an alternative insulating material in packaging industries, which can enhance environmental-friendly packaging products.

Abstract:
The article presents the results of theoretical research to achieve the maximum effect in determination of the economically feasible level of buildings thermal protection. It must be optimal both thermally and economically, an indicator of which there are the costs. Graphical and analytical dependences are given. The research results substantiate the maximum effect when different thermal insulating materials are used. The aim is to increase the efficiency of energy saving measures, reduce their cost by optimizing the cost of thermal energy and insulating materials, determining the optimization criteria and justification for choice the optimal insulating material and its thickness, and determining the optimal thermal resistance, identifying ways to improve energy efficiency and substantiation of the calculation method. One of the most common thermal renovation measures, namely insulation of external walls, is considered. An economic assessment has been conducted, which is an important factor in a certain energy-saving proposition. The solution of the problem is presented, which includes two stages. The result of the first stage is the selection of the optimal heat-insulating material. The second stage is a substantiation of economically expedient thickness of the heatinsulating material. The obtained results make it possible to increase the efficiency of energy saving in thermal renovation of buildings taking into account both energy and economic aspects. In this paper the results of mathematical provement of such factor importance as the thermally conductive cost of the heat-insulating material at their thickness optimization are presented. Determining for the establishment of the normative thermal resistance in the future is the ratio of the cost of thermal energy to the thermal conductivity of the insulating material.

Abstract:
Thermal restoration of building constructions presents a complex of measures during renovation and life prolongation of buildings. It is a solution including restoration of bearing parts of the construction, solutions of moisture questions and the thermal insulation and new surface treatments of the construction. After application of the thermal insulation total energy intensity for heating and cooling is reduced and the thermal comfort inside insulated object is improved. Nowadays at application of thermal insulating systems a huge amount of insulants produced from non-renewable materials (EPS, PUR) is needed or the production of these is energy demanding (rock wool). Some of them, namely foam-plastic insulating materials are not compatible with original walling materials and after its application the diffusion flow is frequently limited in direction to exterior. The paper describes possibilities of production of insulants from flax waste and use of such insulating materials in the field of exterior heat insulating materials for existing objects.

Abstract:
Production of building materials is mostly energy consuming. In the sphere of insulation materials we mostly see rock wool based materials or foam-plastic materials whose production process is demanding from material aspect and raw materials aspect as well. At present the demand for thermal insulation materials has been growing globally. The thermal insulation materials form integral part of all constructions in civil engineering. The materials mainly fulfill the thermal insulating functions and also the sound-insulating one. The majority of thermal insulation materials are able to fulfill both of the functions simultaneously. The paper describes questions of thermal insulation materials development with good sound properties based on natural fibres that represent a quickly renewable source of raw materials coming from agriculture. The main advantage of the materials are mainly the local availability and simple renewability of the raw materials. In addition an easy recycling of the materials after their service life end in the building construction and last but not least also the connection of human friendly properties of organic materials with advanced product manufacture qualities of modern insulation materials.

Abstract:
Increasing the thermal efficiency of drying and firing processes of ceramic products plays an important role for industries that want to remain competitive in the market. Thus, this work aims to evaluate the influence of the type and thickness of thermal insulations, applied on the external sidewalls of an intermittent ceramic kiln, on heat transfer, temperature distribution in the insulating material, maximum external surface temperature, and energy gain, compared to the kiln without thermal insulation. All proposed mathematical formulations are based on the energy conservation, and mathematical procedures are implemented in Microsoft Excel software. Here, it was tested four types of thermal isolators: fiberglass, rockwool, calcium silicate, and ceramic fiber. Results indicate that the greater the thickness of the thermal insulation, the lower the maximum external surface temperature and the greater the energy gain when compared to the kiln without thermal insulation. In addition, fiberglass is the insulating material, among the four types analyzed, which provides greater energy gain and greater reduction in maximum external surface temperature.

Abstract:
Abstract Sustainable thermal insulating materials produced from cellulosic fibers provide a viable alternative to plastic insulation foams. Industrially available, abundant, and inexpensive mechanical pulp fiber and recycled textile fiber provide potential raw materials to produce thermal insulating materials. To improve the fire retardancy of low-density thermal insulating materials produced from recycled cotton denim and mechanical pulp fibers, bio-based fire retardants, such as sulfonated kraft lignin, kraft lignin, and nanoclays, were coated onto sustainable insulating material surfaces to enhance their fire retardancy. Microfibrillated cellulose was used as a bio-based binder in the coating formula to disperse and bond the fire-retardant particles to the underlying thermal insulating materials. The flammability of the coated thermal insulating materials was tested using a single-flame source test and cone calorimetry. The results showed that sulfonated kraft lignin-coated cellulosic thermal insulating materials had a better fire retardancy compared with that for kraft lignin with a coating weight of 0.8 kg/m2. Nanoclay-coated samples had the best fire retardancy and did not ignite under a heat flux of 25 kW/m2, as shown by cone calorimetry and single-flame source tests, respectively. These cost-efficient and bio-based fire retardants have broad applications for improving fire retardancy of sustainable thermal insulating materials.

Abstract:
Energy efficiency of heating networks depends on the costs of the manufacture of insulation materials and components, its installation and exploitation of insulating jacket. As insulation materials for insulation of heating networks, products based on rock wool, polyurethane foam extruded polystyrene foam, foam rubber and polyethylene foam. In this contribution introduced basic principles of calculating the thickness of the thermal insulation of a pipeline by the value of the standard density of the heat flow are given using an example of the use of products based on polyethylene foam. Calculation of the heat flux from the surface of the heat-insulating structure is carried out at a given thickness of the heat-insulating layer if there is a need to determine heat loss (or cold loss). The basis for the calculation is a mathematical model of heat transfer, a developed calculation algorithm and a computer program. The method of installation of thermal insulation depends on the diameter of the pipeline and the selected type of product. Insulating cylinders or cylinders in combination with heat-insulating mats are used for pipelines of small diameters. Roll materials are used to isolate large diameters. Products are fixed on pipelines using mechanical fasteners.

Includes bibliographical references.
The disadvantaged people in South Africa are unfortunate by virtue of their financial status. It was estimated in 1992 that 20 % of the South African population live in informal settlements. The houses in these settlements are found to be very energy inefficient. This study was aimed at developing low cost thermal insulating materials that can be used to increase energy efficiency of the houses in these informal settlements. This was done by firstly studying the properties of thermal insulation materials. Furthermore, common thermal insulating materials in South Africa were studied and evaluated. Only recycled polymeric based materials were examined for selecting the raw materials that were used to investigate the feasibility of the thermal insulating materials from waste material. The experimental work was extended to construct a thermal conductivity rig that was to be used in measuring the thermal conductivity of both the developed and existing thermal insulating materials. The expanded polystyrene obtained from Sagex (Pty) Ltd and polyester obtained from Isotherm (Pty) Ltd. were evaluated and compared to the manufactured recycled polymer slabs and expanded polyethylene foams (EPEF). Expanded polyethylene foam and recycled polymer slab samples were subjected to mechanical and physical testing. A temperature comparison test and thermal conductivity determination were conducted on both the expanded polyethylene foam (EPEF) and recycled polymer slab (RPS) samples. The scanning electron microscope (SEM) was used to reveal the micro-structures of all the developed thermal insulating material samples. The expanded polystyrene and polyester thermal insulating materials were also examined using the SEM. Optical microscopy was only used on RPS samples. It was found in this research, that the properties that govern the viability of thermal insulating materials are: thermal conductivity (k-value), thermal resistance (R-value), combustibility, moisture absorption and the presence of hazardous gases during burning. The temperature comparison test showed that the recycled polymer slab (RPS) and expanded polyethylene foam (EPEF) retards the flow of heat to levels comparable to that of the locally obtained thermal insulation. The comparative cut bar method was found to be relatively cheap to design and it was ideal for the measurement of the thermal conductivity of polymeric based materials. The k-value of all the EPEF samples was measured to be around 0.04 W.m-¹K-¹ and the RPS k-value was found to be 0.05 W.m-¹K-¹. This is attributed to air pockets with lower conductivities values, found within the structure of the polymeric thermal insulating materials. The porous structure is evident from the SEM micrographs of both the EPEF and RPS samples. One grade of expanded polyethylene foam, the SPX80, had accumulated less moisture when moisture absorption was compared with other EPEF samples. The RPS material did have a propensity for absorption of water. The flammability retardant tests have showed that gypsum board has to be incorporated during service for the RPS and SPX80. The mechanical testing results also suggest that both the EPEF and RPS need to be supported when installed in a ceiling, for example.

Abstract:
This research consists of experimental load tests and numerical simulations of structural steel connections with various filler materials to study the effect of non-steel fillers on the connection strength. Non-steel fillers are used in the steel connections to provide thermal insulation by reducing thermal bridging. Eight specimens having steel and polypropylene filler plates of various thicknesses were tested in the laboratory. The collected data were compared to a Finite Element Analysis (FEA) using ABAQUS to validate the numerical results. After validation, three parametric studies were conducted using ABAQUS to provide insight into general behavior of connections with a variety of fillers that could be used as thermal breaks. In addition, an extreme case of having air gaps instead of alternative fillers was also considered. The Research Council on Structural Connections (RCSC 2014) suggests a reduction in the bolt shear strength when undeveloped fillers with a thickness of more than 0.25 inch are used while using any non-steel material is prohibited due the limited research available. Most research studies have investigated the mechanical behavior of thermal breaks in either end-plate moment connections or slip-critical connections. No data is available for thermal breaks in bearing-type connections up to failure. This research aims to study the effects of filler material properties such as modulus of elasticity and strength on bolt strength, as well as investigate whether the current equation in RCSC 2014 is applicable for alternative filler materials like polypropylene that has less than 0.5% of the steel modulus of elasticity and less than 10% of steel strength.

Resumo: Este trabalho apresenta uma abordagem diferente em relação ao conceito de janelas termicamente efetivas, isto é, janelas que reduzem a energia transmitida para dentro ou fora de uma sala. A idéia é usar um painel de vidro duplo preenchido com material de mudança de fase (pcm), cuja temperatura de fusão é determinada por critérios de conforto térmico. A investigação inclui modelamento dos mecanismo de transferência de calor e radiação através do painel, caracterização ótica de janelas convencionais e compostas, e simulação numérica. As amostras incluem vidros comerciais simples de diferentes espessuras e painéis de vidro duplo de diferentes espessuras e espaçamento entre vidros, preenchidos com ar, pcm e finalmente pcm colorido. O modelo é unidimensional transiente e a simulação numérica foi implementada através do método de diferenças finitas na sua forma explícita. Dos resultados da simulação numérica e dos testes de caracterização óticos foram levantadas curvas de ganho térmico, distribuição de temperatura através do painel e evolução da temperaturas da superfícies interna e externas do painel ao longo de um período de 24 horas de forma a verificar o efeito do pcm no desempenho térmico da janela composta
Abstract: This work present a new concept for thermally effective windows, that is windows which reduce the energy transfer to and fIom the internal ambient. This idea behind this concept is to use a pcm fill in the gap between the two glass panels. The fusion temperature of the pcm is selected according to the thermal cornfort criterion. The investigation includes modeling of the mechanisms of heat transfer relevant to the window problem, the thermal radiation through the glass panels, the optical characterization of conventional and composite window configurations and finally the numerical simulation of these configurations. Because of the lack of information on the thermal and optical properties of national gla~s and specially on the composite configuration optical tests were realized to determine the transmittance and reflectivity of simple glass panels of different thicknesses and spacings, air and pcm filled glass panels and finally coloured pcm filled glass panels. The model is a transient one dimensional and the numerical solution is based upon explicit finite difference scheme. the numerical simulations and the optical tests realized allow the determination of the heat gain, the temperature distribution across the glass panels, the outlet and the inlet instantaneous surface temperatures and finally the overall thermal performance of any glass panels including the proposed system

Abstract:
Constant conductivity values of insulating materials are typically used in building design and assessment. However, the thermal conductivity of insulating materials changes with temperature. Linear temperature-dependent law exist for many inorganic fibrous materials such as fiberglass or rockwool, that exhibit a decreased thermal conductivity (better performance) at low temperatures, and a higher thermal conductivity (weaker performance) at high temperatures. However some insulating materials, especially the petrochemical-foamed insulation such as the polyisocyanurate (PIR), exhibit less regular behavior with poorer performance at cold temperatures. In this scenario, using constant thermal resistance values results in actual building are different from the design predictions, with increasing building energy consumptions, greater risks of condensation issues, and decreased occupant comfort. This thesis aims to understand the impact of the thermal conductivity change due to temperature when the insulation is used for exterior walls and flat roofs. Experimental results were used in detailed building energy simulations in the continental and humid temperate climates of Toronto and Milan respectively. Common rigid insulating materials boards were taken into account, such as fiberglass, rock- wool, polyisocyanurate, extruded polystyrene, and a hybrid insulation system, that is constituted by two different materials, polyisocyanurate and rockwool.

Cette thèse s'inscrit dans un objectif à long terme de déterminer in situ (et/ou en usage) les propriétés thermiques des matériaux isolants du bâtiment. Notre objectif est de réduire l'écart entre la mesure en laboratoire et la performance réelle des isolants dans les parois de bâtiments. Nous nous sommes fixés deux objectifs principaux au cours de cette étude: 1- Étudier la possibilité d'utiliser la sonde cylindre à choc thermique pour la mesure des caractéristiques thermiques des matériaux isolants du bâtiment. 2- Étudier le comportement thermique d'un isolant en usage en utilisant un montage basé sur le principe de la boite chaude gardée. Cet équipement permet d'effectuer des études dans des conditions climatiques en température et en humidité proches de situations réelles supportées par l'enveloppe d'un bâtiment. Ce travail a permis d'identifier des verrous lors de l'utilisation d'une sonde à choc thermique pour caractériser des matériaux isolants. Il a aussi montré l'intérêt de la boite chaude gardée pour effectuer des études dans des conditions réelles et pour étudier les transferts de chaleur et de masse dans les parois de bâtiments

Climatic conditions in temperature and humidity close to real situations can be submitted supported by hot and cold cells. This work has shown the interest of using thermal probe to characterize insulating materials. Guarded hot box is also interesting for studies in real conditions and to followheat and mass transfer in buildings walls

Abstract:
The monograph summarizes and systematizes the results of experimental and theoretical studies of thermal insulation systems of building structures, technological facilities, transport facilities, and cold preservation. The criterion for the effectiveness of system insulation solutions is energy efficiency as a criterion for a comprehensive assessment, including both taking into account the direct reduction of energy costs during the operation of insulation shells, and the costs of installation, maintenance of structures in working condition, evaluation of the operational resistance of materials and durability of system solutions as a whole. Modern types of thermal insulation materials based on gas-filled plastics, foamed glass, foamed rubber and products based on mineral fibers are considered: stone wool, glass wool and glass fiber, basalt fiber. It is intended for researchers, specialists in the field of materials science, technologists — developers of new types of thermal insulation materials and constructors, designing products from them, as well as for teachers and university students. It can be useful for a wide range of people interested in construction and energy saving problems.

Abstract:
Buildings are a significant source of energy consumption in the US and worldwide, and conditioning building interiors occupies a major portion of that expenditure. At the building level, a particular scenario can occur where it becomes more advantageous for a structure’s walls to be “open” to the outside, as opposed to remaining “closed”, in an insulating state. For instance, a cool night may follow a hot summer day after the sun sets, but traditional insulation captures heat built up inside a home. A clear, sunny day may also heat a building’s exterior during a cold winter day, and heat transfer to the interior would be more desirable than insulation. This paper presents a study of a concept, termed “smart insulation”, that could be used in such scenarios to take advantage of beneficial thermal gradients in order to save heating and cooling costs. Enabling heat transfer without moving air can also help control humidity within interior spaces, as well as limit noise either from moving air or through open windows. Unlike traditional insulation that maintains a specific insulating value during its useful life, smart insulation changes between an insulating and a conducting state depending on the thermal gradient. Some design concepts have been fabricated and were tested in an insulated chamber that provides a “hot side” and a “cool side”. In the test chamber, temperature measurements were taken and the insulating capacity of each design specimen was calculated. Results indicate that the designs have potential to operate between two states (with the best case ranging from 11% to 61% of a benchmark insulation case) and effectively provide sustainable heating or cooling by capitalizing on ambient outdoor conditions.

Abstract:
For gas turbines and advanced nuclear power reactors, ceramic materials are used to provide thermal insulation to metallic components. Reducing the thermal conductivity of these ceramic materials allows further decrease in either metal surface temperature or thickness of the insulating materials. In this paper, our past research on the effects of oxide dopants is summarized with a focus on thermal properties. Metal oxides of different valence, ionic radius, and mass were incorporated into yttria partially stabilized zirconia (7 wt% Y2O3-ZrO2) using mechanical alloying process. The powder blends were consolidated using sintering and plasma spraying. The oxides investigated included trivalent Yb2O3, Sc2O3 and Cr2O3, tetravalent CeO2 and TiO2, and pentavalent Nb2O5 and Ta2O5. While all oxides provided improvement to thermal conductivity reduction, the most significant effect on reducing the thermal conductivity of 7YSZ was found by using trivalent oxides. Furthermore, the effect of dopant was also heavily influenced by the molar percentage of dopants.

Abstract:
The theory of heat transfer through low density insulating materials explains the importance of thermal radiation in the overall heat transfer. As a matter of fact, in many semitransparent insulating materials, radiation has a considerable influence on measured thermal conductivity. In this work we continue the investigation (both experimentally and theoretically) on the heat transfer through low density insulating materials that we started some years ago and whose results have been presented in some International Conferences. Test have been done on low density insulating materials: expanded polystyrene with a density of 10 kg/m3 and polyester fibres with a density of 9 kg/m3 (these last tests are not yet completed and will not be discussed in this paper). The transfer factor T was measured in the heat flow meter apparatus of our laboratory [1]. The first measurements have been done with the two surfaces of the apparatus uncoated (emissivity ε = 0.91) at a mean test temperature of 283 K (10 °C) and then with the specimens enclosed in the aluminium foils (emissivity ε = 0.045) at the same mean test temperature. The results obtained from the measurements of the transfer factor T pointed out that a change of the emissivity ε of the surfaces from 0.91 to 0.045 caused a considerable decreasing of the transfer factor. Then the same panels have been cut into two slices and the aluminium foil has been interposed also between the slices, as shield, and the transfer factor was measured again in both cases: at first with the surfaces of the apparatus uncoated and then with the surfaces of the apparatus coated with the aluminium foils. In both cases the decreasing of the transfer factor τ was not negligible. The radiation extinction parameters have been then measured with a spectrometer and a model has been found to predict the transfer factor T in function of the testing conditions. We can conclude that in presence of a thin reflective metal cover placed on a low density insulating material, the thermal conductivity decrease immediately (about 7%) with a significant improvement of the thermal characteristics of the insulating material. If we put then some low emissivity foils between the slices of the material, another considerable decreasing of the thermal conductivity can be obtained (about 10%) and in presence of both aluminum foils (inside and outside). This fact confirms the importance of the contribution of radiation in thermal transmissivity of low density insulating materials and gives the possibility to reduce and to predict the thermal performances of such a material.

Abstract:
Investigations of recent firefighter line of duty deaths caused by rapid fire progression have highlighted a deficiency in firefighters’ understanding of how certain tactics affect the fire dynamics of ventilation-controlled fires. Many fires are in a ventilation-limited, decay state by the time firefighters arrive at the scene, meaning that introducing additional ventilation to the environment has the potential to cause rapid and intense fire growth. To more effectively teach firefighters about the potential effects of ventilation on a compartment fire, ventilation-controlled fires should be gener- ated during training. Safely creating such fires while maintaining compliance with NFPA 1403: Standard on Live-Fire Training Evolutions allows instructors to educate students on this important principle of fire dynamics in the training environment. Structures utilized for live-fire training have evolved from typical concrete burn buildings to now include smaller purpose-built props, like those constructed from steel shipping containers or wood and gypsum board. Such props have been embraced by organizations due to their cost-effectiveness and potential to improve fire behavior training. Obtaining a thorough understanding of the capa- bilities and limitations of such props is critical for instructors to convey accurate messages during training and properly prepare firefighters for scenarios they’ll encounter in the field. Experiments were conducted to quantify the fire environment in L-shaped props with different wall constructions. One prop had an interior wall lining of gypsum board over wood studs and fiberglass insulation. The two other props were constructed from metal shipping containers with corrugated steel walls; one had ceilings and walls comprised solely of the corrugated steel, while the other had ceilings and walls comprised of rolled steel sheeting over mineral wool insulation with the corrugated steel wall as its backing. Three fuel packages were compared between the props: one contained furnishings mainly composed of synthetic materials and foam plastics; another contained wooden pallets and straw; and the third contained wooden pallets, straw, and oriented strand board (OSB). A stochastic approach was used to compare data between replicate tests and quantify the repeatability of the different props and fuel packages, all of which were deemed sufficiently repeatable. Comparisons of data between the three props revealed that thermal conditions between experiments in the two metal props were indistinguishable, suggesting that the additional layer of insulation did not significantly alter the fire environment. Additionally, thermal conditions in the gypsum-lined prop were more severe than those in the metal props. The effects of ventilation changes on fire conditions were also analyzed across various prop and fuel load combinations. Lastly, the response of the thermal environment in each prop during interior suppression was evaluated, and the results implied that the thermal exposure to the firefighter was more severe in the metal props than the gypsum prop for a brief period following the start of suppression.
