In this paper, the development and properties of floating bead insulation mortar were introduced. Based on the experimental study, a new kind of exterior wall external thermal insulating mortar had been successfully produced. For this material, fly ash floating bead and expanded pearlite which was modified by hydrophobe were taken as the lightweight aggregate, meanwhile, Portland cement was used as the inorganic binder, also the fiber and polymer were taken as the additive. The results of experiments indicated that properties of fly ash floating bead insulating mortar, such as thermal insulation, strength, crack resistant and climate resistant, were superior to those of expanded pearlite insulating mortar. On the other hand, other properties, such as bulk stability, aging resistant, climate resistant, crack resistant and fireproofing, construction workability were much better than those of expanded polystyrene sheet ( EPS) insulating mortar.

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.

Because of the rigorous regulations in the 21st century it has become a serious task for designers to find more effective ways for thermal insulation. One of these options is the application of nanotechnology-based materials. Among nano-scale structured materials the most uncertainties are found about the thermal insulating quality of thermal insulation coatings consisted of vacuum-hollow nano-ceramic microspheres. Complete agreement had not been already found about the mechanism of their insulating effect. In order to explore and describe the thermodynamic process inside nano-ceramic coatings (NCC) 6 series of heat transfer resistance experiments were performed in 2014-2017. Several building structure configurations with 12 different orders of layers were tested with a standard heat flow meter. On basis of these results it could be concluded that in case of nano-structured materials convective heat transfer coefficient might be taken account in different way than in case of traditional macro-structured thermal insulation materials.

Energy rehabilitation of buildings using airtight insulating materials based on expanded polystyrene is often accompanied by the formation of moisture problems in the enclosure wall footing. Moisture progress in the rehabilitated structure is simulated using modern moisture transient models in Delphin software. Combinations of the developed plate thermal insulating materials based on calcium silicate and the conventional thermal insulation panels based on expanded polymer have been designed to address the moisture problems. This article describes the function of this solution during the reconstruction of a house built from full clay bricks with malfunctioning waterproofing in the lower house construction.

Building construction has gone for tremendous changes during the last decade. The total building architecture including construction system and external finish has improved tremendously. Now a days even residential houses are tailor made to individual requirements. As we all know with the improvement in quality of life, earnings, living style, the building construction methodology and construction materials have got modified to suit the life style of people. Previously in residential houses use of room air conditioner was a rare commodity, but now it has become very common. In fact now we find that air conditioning has become a necessity. The art of living has changed and human comfort is given a lot of importance. Buildings including residential houses hence consume lot of energy now a days. Buildings world over consume more than 40% of the Energy Generated followed by Industry (32%) and Transportation (28%). With the increase in electronic gadgets in the houses along with air conditioning and heating system energy consumption becomes enormous. It is in this context of energy consumption and human comfort the function of Thermal Insulation in buildings has become an important construction element. Thermal insulation is directly linked to human comfort and reducing energy consumption that is creating Energy Conservation.
