Better Than

A weathering resistance test was made to exterior wall external insulation systems with foamed glass decorated with coating and facing brick in this paper. The results show that the change of ambient temperature has large effect on the external insulation systems. Because of the phenomenon of stress concentration, there are many cracks in the windows position. On the other hand, the system decorated with facing brick has much less cracks than the system with coating, and its surface layer has no hollowing. So from the perspective of weathering resistance, the exterior wall external insulation systems with foamed glass decorated with facing brick is better than the system decorated with coating.

Strong Winds

Highly insulated envelope or external insulation systems are being applied in recent energy saving buildings to reduce the heat loss through envelope. Internal insulation systems are applied to most apartments in Korea because they are inexpensive and convenient to construct. However, the internal insulation systems have poor performance due to the heat bridges through structures such as slabs. The external insulation systems have better thermal performance because the heat bridges through the structure are rarely formed. But it has problems regarding the external insulator separation due to strong winds, spread of fire due to insulator combustion in case of fire, formation of heat bridges through the connectors between structure and external insulation. To supplement the weaknesses of the internal and the external insulation systems, a sandwich insulation system has been suggested. In this study, the thermal performance of sandwich insulation system for apartment buildings was evaluated according to two type of the form-tie material.

Family House

This study deals with small investors’ demands on thermal insulation systems when choosing the most suitable solution for a family house. By 2050, seventy percent of current buildings, including residential buildings, are still expected to be in operation. To reach carbon neutrality, it is necessary to reduce operational energy consumption and thus reduce the related cost of building operations and the cost of the life cycle of buildings. One solution is to adapt envelopes of buildings by proper insulation solutions. To choose an optimal thermal insulation system that will reduce energy consumption of building, it is necessary to consider the environmental cost of insulation materials in addition to the construction cost of the materials. The environmental cost of a material depends on the carbon footprint from the initial origin of the material. This study presents the results of a multi-criteria decision-making analysis, where five different contractors set the evaluation criteria for selection of the optimal thermal insulation system. In their decision-making, they involved the requirements of small investors. The most common requirements were selected: the construction cost, the construction time (represented by the total man-hours), the thermal conductivity coefficient, the diffusion resistance factor, and the reaction to fire. The confidences of the criteria were then determined with the help of the pairwise comparison method. This was followed by multi-criteria decision-making using the method of index coefficients, also known as the method of basic variant. The multi-criteria decision-making included thermal insulation systems based on polystyrene, mineral wool, thermal insulation plaster, and aerogels’ nanotechnology. As a result, it was concluded that, currently, in Slovakia, small investors emphasize the cost of material and the coefficient of thermal conductivity and they do not care as much about the carbon footprint of the material manufacturing, the importance of which is mentioned in this study.

Fire overflow on exterior wall with thermal insulation system has been studied by numerical simulation. The spread laws of fire overflow are analyzed through the temperature distribution near the window. The computational results are compared with those of test in the Exterior Insulation Fire Barrier Technical Guidelines (EIFBTG). It has been found that the calculated maximum temperature points is closed to the test on the first floor, the first ceiling, and the points near the above two windows. However, there are differences between two kinds of results above two floors and ceilings, and the points near the first window. It has also shown that when the HHR is 7.5KW, the scope of damage of exterior thermal insulation layer is about 15 square meters near the window. The research would provide reference for fire protection design of exterior wall thermal insulation in the high-rise buildings.
