Paper deals with practices significantly affecting quality and durability of external thermal insulation of the building envelope. Analysis is made by the survey of existing external constructions of buildings, experimental detection of bearing capacity of expansion anchors, including theoretical modelling of their activity in the external wall processed by the ANSYS program. Paper briefly summarizes new findings detected by control and testing activities for additional thermal protection of the building envelope.

Building palisade structure is the most important part of the wall, so the external wall thermal insulation technology has become an important part of building energy efficiency. After the author found the domestic use of insulation materials in a variety of forms, different use method makes the external wall thermal insulation system has a problem. The analysis of the cause of the problem at the same time, this paper discusses how to use of selected materials and improving the construction methods to avoid the happening of the accident.

With excellent flame retardation and thermal insulation properties, SY self-temperature regulation and phase change energy-saving wall insulation material (the material) is composed of concrete and volcano perlite. At present, applied research of this material is not very thorough,especially under the condition of temperature variation, seasonal wind change in North China. In this paper, finite element analysis of external wall insulation layer of the Experimental Teaching Building in Taiyuan University of Science and Technology under negative wind pressure effect is performed. The negative wind load calculated is applied to the surface of the thermal insulation layer as uniform load, and the results show that the material used in the building which shorter than 80 meters in the Taiyuan area has no shedding or destruction under the negative air pressure. This material is safe and available.

A great part of energy produced in Europe is consumed by old residential buildings. Consequently, it is necessary to retrofit energetically non-efficient buildings. However, there is a mass financial gap between cost effective retrofitting and upgrading to nearly zero energy building levels. The efficiency of apartment building modernization under current requirements applicable in Lithuania and the requirements for 2020 was analysed, focusing on thermal insulation of external walls. Six cases of residential building modernization in Lithuania were studied estimating criteria that are among the most important for implementation of apartment building modernization, such as the total cost of the external wall modernization, simple payback period, work duration, and other parameters related to the characteristics of thermal insulation systems. The weights of the criteria were calculated after an expert survey and using integrated SWARA-TODIM multi-criteria decision-making (MCDM) method the best alternatives were ranked. After analyzing the differences between the current situation and upcoming requirements for rendered and ventilated type of façades, it can be stated that the final result depends more on price, duration of works, payback period, energy losses and water vapour diffusion than on the type of façade or insulation requirements applied at present or future.

The production process and application of large composite external wall panels (composite panels for short) are introduced in this paper. Composite panels with both load bearing and thermal insulation were formed by pouring normal concrete (NC) and ceramsite foamed concrete (CFC) continuously according to particular technological requirements, which made two layers into a seamless whole. The layers of NC and CFC are for load bearing and thermal insulation respectively. The composite panels were manufactured in the scale of industrial production, and applied to several energy saving prefabricated buildings successively, instead of polystyrene sandwich composite panels (sandwich panel for short) as external wall panels. There are several obvious advantages of the composite panel over the sandwich panel or outer benzoic board. Firstly, it solved the problems of durability of polystyrene and the complex production process of the sandwich pane, the production process of the external wall was thus greatly simplified. In addition, the fire risk was much reduced.

Purpose – The purpose of this paper is to modify light hollow polymer microsphere (LHPM) with titanium dioxide nanoparticles (nano-TiO2) to improve its compatibility with latex and apply the obtained nano-TiO2/LHPM composite particles in external wall thermal insulation coatings. Design/methodology/approach – The nano-TiO2/LHPM composite particles were prepared via vigorous stirring. The morphology and chemical composition of the produced nano-TiO2/LHPM composite particles were characterized using scanning electron microscopy, energy dispersion spectrum, thermo-gravimetric analyzer and Fourier transform infrared. The performance of this new composite coating was evaluated by checking its stability, density, radiation reflectivity, thermal conductivity and the resulting insulation temperature difference when forming coating film. Findings – It was found that a 9:1 mass ratio of nano-TiO2/LHPM with total 10 weight per cent composite particles in the thermal insulation paint showed low density, good stability, low thermal conductivity (0.1687 W/m·K) and high insulation temperature difference (5.8°C). Research limitations/implications – The LHPM can be modified by other nanoparticles to improve its insulation performance in thermal insulation coatings. Practical implications – This work provides a simple, robust, but effective approach to produce new thermal insulation coatings with nano-TiO2/LHPM composite particles. Originality/value – This method for surface modification of LHPMs is novel and the modified hollow polymer microspheres could be applied to external wall insulation coatings.
