Floor Insulation

Floor insulation is installed beneath the floor’s surface. It's ideal for reducing heat loss and improving energy efficiency. The expert design provides a barrier against heat transfer between common spaces. The type of material you use in this area of your property will depend on whether you have a solid or suspended floor.

Solid flooring is often made from concrete, which means it is designed to bear heavy loads including footfall and furniture. Because of this, the solid floor insulation will also need the same benefits. Rigid floor insulation boards such as XPS and PIR foam are perfect because they have good compression tolerance as well as high R-values, meaning they can provide incredible thermal performance with less thickness.

On the other hand, if you have suspended floors made from timber, you may want to consider mineral wool. The main benefit of this is that it is flexible, so when it comes to fitting around joists, it is easy to install and will still expand to fit into tight and awkward spaces. We recommend the ROCKWOOL flexi slab range as suspended floor insulation.

Regardless of whether you have a wooden floor or carpet, cold can transfer through your floor, resulting in it becoming more expensive to heat up. Installing underfloor insulation reduces this issue, creating a more energy-efficient and comfortable living environment for improved thermal performance. Also known as underfloor insulation, it can also be manufactured from materials such as glass woolfoam, PIR, eco-friendly recycled rubber, or sheep's wool.
