EXPOL UNDER- FLOOR INSULATION INSULATION Vs DAMPNESS

The placing of Expol Under-floor Insulation beneath a timber floor provides a high value thermal insulation barrier between the interior and exterior of the house. Air heated in the house will remain warmer for longer. Cold air and draughts will not enter the house through the insulation.

If your home is damp under the floor, there could be several causes:

  • Check if there is air flow beneath the floor provided by vents around the perimeter of the house, or, horizontal timber slats spaced apart to allow air to circulate.
  • There may be trapped water under your home, caused by insufficient drainage, or, run-off from surrounding areas, which may be tracking through your property and under your floor.

Placing a vapour barrier such as foil or polythene as insulation beneath your floor may create condensation in the house, or even trap water within the house.

Insulating under your floor WILL save heating costs and keep your home warm, it may not solve all of your dampness problems.

It is important to explore all possible causes for dampness and deal with them as suggested above.
