How to Fill Floorboard Gaps

Cold draughts created by the gaps between floorboards can lead to chilly and uncomfortable rooms and increased heating bills during the winter months. Even rooms that have carpet and underlay fitted often have gaps between the skirting board and the floor that allow significant heat to be lost.

Traditional floorboard gap filling techniques and products are time consuming, messy to install and will often fall out over time. DraughtEx is a proven floorboard gap filler, designed to reduce the cold draughts and improve the comfort and energy efficiency of your home.

Suitable for Different Size Floor Gaps

DraughtEx is the best material for draught proofing floorboards because its flexible properties allow it to compress and expand with the natural movement of the floorboard gap meaning it doesnt fall out over time. It can also be compressed into floor gaps much smaller than its original profile, enabling you to fill even the smallest of gaps in floorboards.

Available in 3 sizes, thin, standard and thick, DraughtEx gives you the flexibility to combat all your floorboard draughts and if you are unsure which size to order, you can simply order a sample pack and try them out.

Fantastic Energy Savings

Did you know that in a 12ft x 12ft room the gaps in floorboards create a draught that is equivalent to leaving a small window open! This can result in significant heat loss, uncomfortable rooms and unnecessarily high heating and energy costs during the winter months.

The Energy Saving Trust estimates that filling draughty floorboards can save a household up to £40.00 per room per year on energy bills and reduce its CO2 contribution by around 110 kg.
