When installing from above, suspended timber floor insulation can be placed on a suspended netting. Using the natural friction fitting of the lightweight slabs will ensure tight placement – avoiding air leaks.
When installing from below, insulation can be pushed against the existing floor boarding. Placing some lathing or netting underneath will help keep products in place.
With a concrete floor, insulation slabs can be mechanically fixed against the underside of the floor.
- Check the existing floor beams – assure all beams are in a good state, especially where they rest in the wall.
- Moisture control – place a vapour barrier on top of the insulation to avoid moisture building up in the wooden floor.
- Use protective gear – when installing from below make sure you use proper protective gear such as goggles and gloves.
