Adding insulation to suspended timber floors is a common way to improve a home’s thermal performance, reduce heating costs, and enhance comfort. This can be done by lifting the floorboards or, if access is available from below, by adding insulation from the underside.
Before Insulation Board it is important to ensure that the subfloor is clean and free of any debris. The boards can be easily cut to size using a saw, and should be laid out in a staggered pattern to ensure a tight fit. When installing the boards, it is recommended to use a low-expansion foam adhesive to secure them to the subfloor, ensuring a strong bond.
Once the boards have been installed, it is important to ensure that any gaps or joints between the boards are sealed with a suitable tape or sealant. This will help to prevent any air leakage and maintain the overall effectiveness of the insulation. Once the insulation is fully installed, the final flooring can be laid directly on top, without the need for any additional underlay.
