Moisture Management for Suspended Timber Floor Construction

Many suspended timber floor constructions have discontinuous insulation between the joists. That leaves an opening to improve moisture management and airtightness – by fitting a Tyvek® membrane and carefully sealing the gaps and joints.

 

 
 
 
 
 
 

 

Tyvek® membranes are ideal for suspended timber floor construction. They are vapour-open, yet greatly reduce air flow when correctly installed. This helps to minimise underfloor condensation (and hence the risk of mould or decay) while improving the thermal efficiency of your floor and building.

Achieving Airtightness
Tyvek® Supro membranes are sturdy and durable. They provide adequate support for the insulation, and are recommended for use in suspended timber floor constructions. To achieve optimal airtightness in suspended timber floor construction, however, it is important to fit them methodically. Airtightness can only be achieved if the membrane is laid continuously with sealed laps.
