Comparison Thermal Conductivity and Cost of Materials Specified for Thermal Insulation of the Building's Facade

Abstract

Situation on insulation market, not only in Czech Republic, is confused for the general public. This paper tries to streamline this fact. Here are described more than 30 types of thermal insulations divided into 6 categories. Each category is detailed described by physical parameters and each is sequentially selected about 5, which are most frequently using like thermal insulation of the building's façade, without air gap. Elementary parameters, which are most important from investors view, are finances. Like a basic reference value was chosen thermal conductivity of insulation and for economical compare was chosen uniform thickness insulation on building envelope 100 mm. On the basis of these two values are insulation chosen. In this paper are results clearly graphically compiled.From graphs it is clear, that most of thermal insulation's values of thermal conductivity are very similar, bud prices of insulations can be usually substantially different. From this is evident, that some of insulation are so popular, because their producer have excellent marketing and promotion.
