5. Thermal insulation for terraces
5.1 Insulation
On terraces, thermal insulation is provided by a number of products, including :
expanded polystyrene – (EPS) – λ = 0.037 to 0.046 ;
extruded polystyrene – (PSX) – λ = 0.031 to 0.036 ;
polyvinyl chloride – (PVC) – λ = 0.031 to 0.034 ;
polyurethane – (PUR) – λ = 0.020 to 0.031 ;
cellular glass – λ = 0.050 ;
vermiculite, perlite – λ = 0.060.
Good thermal insulation has a very low λ coefficient; polyurethane foam (PUR) with λ = 0.020 to 0.031 is currently one of the best insulators. Other,...
