What is common and what is the difference between polystyrene and epx
Compared to polystyrene foam, polystyrene foam has slightly more profitable indicators for thermal conductivity, water absorption, compression and bending strength, but higher cost.
Therefore, in situations when it is necessary to warm the surfaces in conditions of constant exposure to moisture, freezing of soil, it is better to use extrusion foam polystyrene. For insulation of facades of buildings, apartments, sufficient use of foam. The durability of operation depends primarily on compliance with all the requirements of the work technology and the application of the relevant materials. In order for thermal insulation to be safe from the point of view of fire safety, as well as safe for health – insulation cannot be done from the inside of the premises.
