Solid floor insulation is typically installed below the ground floor concrete slab; however, it can also go above the concrete slab. When the insulation is placed below the concrete slab, the thermal performance of the building is increased and delivers steady internal temperatures. If you insulate above the concrete slab, the building will be quicker to respond to the heating system.
Solid floor insulation has high compressive strength and we supply a range of products including PIR, XPS, EPS and rock mineral wool. Some products are also suitable for heavy-duty floor build-ups and underfloor heating.
The solid floor insulation we supply will help you to reach your energy-efficiency requirements with high thermal performance. To find out details of the different building regulations across the United Kingdom, please head to our support and resources section.
To ensure your solid floor is protected from damp, you could consider installing a damp-proof membrane in the build-up. You can find our range of damp-proof membranes at our membranes and barriers section.
