AbstractFor the best possible thermal-technical properties of building structures it is necessary to use materials with very low thermal conductivity. Due to the increasing thermal-technical requirements for building structures, the insulating materials are developed. One of the modern thermal insulating materials is so-called aerogel. Unfortunately, this material is not used in the field of external thermal insulation composite systems because of its price and its properties. The aim of this paper is to present possibilities of using this insulating material in the civil engineering - specifically a usage of aerogel in the production of windows.

The paper presents the results of the study of feasibility of obtaining high-quality foamed thermal insulation materials based on a silicate matrix with addition of dolomite. It has been found out that the preliminary activation of a suspension based on a silica-containing component at a temperature of 90°C for 5-7 minutes allows accelerating the coagulation of silica fume and the synthesis of sodium silicates. Optimal foaming conditions for the charge frothing are 650-700°C for 25 minutes. There have been obtained foam silicates with a relatively uniform finely porous structure and stable physical and technical properties with density 0.38-0.48 g/cm³, strength up to 3 MPa, thermal conductivity 0.048-0.054 W/(m·K).

Thermal Insulating

The development of new thermal insulation materials needs to evaluate properties and structure of raw material, technological factors that make influence on the thermal conductivity of material. One of the most promising raw materials for production of insulation material is straw. The use of natural fibres in insulation is closely linked to the ecological building sector, where selection of materials is based on factors including recyclable, renewable raw materials and low resource production techniques In current work results of research on structure and thermal conductivity of renewable resources for production thermal insulating materials are presented. Due to the high abundance of renewable resources and a good its structure as raw material for thermal insulation materials barley straw, reeds, cattails and bent grass stalks are used. Macro- and micro structure analysis of these substances is performed. Straw bales of these materials are used for determining thermal conductivity. It was found that the macrostructure has the greatest effect on thermal conductivity of materials. Thermal conductivity of material is determined by the formation of a bale due to the large amount of pores among the stalks of the plant, inside the stalk and inside the stalk wall.http://dx.doi.org/10.5755/j01.ms.17.2.494

The paper analyzes the problems associated with the fire hazard of the application of thermal insulation and finishing systems of facades of buildings, which directly depends on the design solution of the thermal insulation system and the type of thermal insulation material. The generalized requirements for physical and technical indicators of the quality of heat-insulating materials; the possibility of applying facade heat insulation structures depending on their class, the height of the houses and the combustibility of the materials of the heat-insulating and finishing layers; fire-technical characteristics of expanded polystyrene are considered. The threats of fire spreading by thermal insulation systems of facades are analyzed and possible ways of its propagation between floors are considered. It is concluded that the use of combustible thermal insulating materials poses an increased danger to life and health of people during a fire. The problem of ensuring the fire safety of buildings, in which the insulation and finishing systems of exterior walls are used, depends on a number of factors and requires a more thorough study.

Thermal Conductivities

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.
