Installing an underfloor barrier is one of the most cost-effective ways to improve your home and prevent the need for any future underfloor repairs. A dry underfloor will also prove to be inhospitable for small household pests that need excess moisture to be able to survive. Rats and mice are also deterred by the plastic underfloor vapour barrier.

By keeping your underfloor dry you can protect your timber from mould problems and rot issues, odours and allergenic mould spores while improving your underfloor insulation.

Problems associated with underfloors

The main problem with a dirt or vented concrete underfloor is that warm air rises into your home and brings with it air that was previously in your underfloor. This will often have excess moisture in it, mould spores and anything else that may have been in your underfloor. An underfloor vapour barrier will ensure that your house does not overheat from the hot air rising up through the floor in the summer but also in the winter months keep the cold from entering your home through your underfloor.

In the above image you can see that there is a damp patch on the floor and the underfloor insulation is starting to fall away from the underfloor ceiling and therefore the property will not be getting the benefit from it.
