For measuring the thermal insulation performance of the materials an isolated (adiabatic) twin chamber was used. The walls of the chamber were built from and separated to two sides (warm-cold) with EPS with about compressive strength 200 (KPa). The thickness of the surrounding walls was 30 ...
Why We Put More Insulation in Attics than Walls of Buildings? The reason for putting more insulation in the attic is twofold: First, in older insulated homes, air near the ceiling may be as much as 10 degF. hotter than air at the floor. So the rate of heat loss was [and may still...
