Gapseal Roll stops the draughts that come through your floorboards without losing the natural look of wooden flooring. Gapseal can help save on energy bills and is an easily fitted (without adhesive) draught excluder which fits into the gaps between floorboards, keeping cold air out, and is almost invisible. It is an alternative to putty type fillers or PVA glue/sawdust mix and will not fall out when floorboards expand and contract. It can help save money on your heating bill, and can also keep smells, noise and insects from entering your rooms through floorboard gaps. Suitable for floorboard gaps up to 9mm wide. Not suitable for ‘tongue and groove’ floorboards.
