Windproofing, air tightness and load-bearing properties in structures with plasterboard. Gipsskivor - nagra tekniska aspekter pa energibesparing.

It has been shown by Bankvall that forced convection reduces the efficiency of thermal insulation considerably. The reductions can become drastic if the inner skin is not airtight. The leakage around a switch or junction box issufficient. The material in the windproofing skin must be sufficiently impermeable. If complicated joints are to be avoided it must retain its dimensions in varying humidity. If the inner skin is not tight caulking or taping the joints in a plasterboard skin halves the leakage.
