The Kingspan Kooltherm K103 Floor Insulation Board is intended for installation under concrete floor slabs, screed, or timber floors. While installing insulation under floorboards is less complex than in pitched roofs, it is crucial to ensure secure and correct installation. It is important to inspect the space under the floorboards for any rot or structural issues. The boards can be placed between the floor joists, and it is recommended to use equipment to secure them. Consulting a professional before starting insulation projects is always advisable.
