A properly insulated suspended floor needs to be airtight to function properly and prevent risk to the construction, as the airtight membranes prevent condensation and stop cold air entering the building while stopping warm air from leaving. This is important and greatly improves the overall quality of the insulation.

In a suspended timber floor, you will want to structure it as follows :

1. The Breather membrane is placed on the bottom, wrapping it around the joists. Securing battens to the membrane and the joists followed by wrapping any overlaps and penetrations with airtight tape.
2. Placing insulation in-between the joists.
3. Covering the top of the floor in a vapour control layer and sealing overlaps with airtight tape.
4. Placing floorboards overtop.
