Investigation of both thermal parameters and applications of closed-cell plastic thermal insulation foams with building energetic aspects

Abstract

Nowadays, if one wants to renovate or build a building, the question of thermal insulation is an essential construction process. Polyurethane is a key thermal insulation material that belongs to plastic foams. It can be applied as a spread or board heat-insulating material. Its thermal insulation properties are superior compared to polystyrene, but still a bit neglected. In this article, we would like to perform thermal investigations executed on a new type of polymeric foam such as polyisocyanurate. We will present acceptably low thermal conductivity (~ 0.022 W m-1 k-1), raised specific heat capacity (~ 1400 J kg-1 K-1) and calorimetric (bomb and differential) measurement results completed with optical microscopic images. Moreover, scanning electron microscopic analysis and X-ray diffractometry will be also presented. The results will be used for cost calculations applied by buildings and will show justified reasons for its application based on structural measurements too. The results are extremely encouraging.
