Concrete Floor Insulation TP10/TF70/TW55
Concrete floor insulation is essential in modern construction, as it helps create comfortable, energy-efficient spaces. It is designed to reduce heat loss through the floor while maintaining load-bearing strength.
What are concrete floor insulation boards?
Concrete floor insulation boards are specialised rigid panels designed for installation underneath or above concrete slabs. They are made from high-performance materials such as PIR (polyisocyanurate), EPS (expanded polystyrene), XPS (extruded polystyrene ) or advanced vacuum insulation boards. When installed, these panels form a continuous thermal layer to prevent heat from escaping into the ground.
What is concrete insulation used for?
Concrete insulation is primarily used to improve the thermal efficiency of solid or ground floors. It is suitable for homes (kitchens, living rooms, and extensions), garages, and commercial workshops where strength and insulation are both essential.
Depending on the type of building, its function, and the weight it supports, you will need an insulant with the correct compressive strength to withstand pressure without losing performance.
For instance, garages and loading bay floors require an insulant with a higher compressive strength than standard living spaces.
Types of concrete floor insulation
There are various types of insulation suited for concrete slabs:
PIR insulation boards
These are lightweight boards that offer outstanding insulation and moisture resistance.
Kingspan Optim-R Boards
OPTIM-R boards are thin vacuum insulation panels. Despite their slim profiles, they deliver high thermal performance and are perfect for low-floor-height projects.
EPS insulation boards
These are expanded polystyrene panels. They are cost-effective and simple to install.
XPS insulation boards
These are eco-friendly panels certified for low chemical emissions, supporting healthier indoor air quality and sustainable construction.
Benefits of insulation for concrete floors
Concrete floor insulation offers numerous benefits for property owners. Some of these are:
- Better heat retention, energy efficiency, and lower energy costs.
- Enhanced comfort with warmer indoor surfaces.
- Reduced carbon emissions.
- Protection against cold bridging and condensation.
- Lasting performance.
- Minimal maintenance.

FAQ
How thick should concrete floor insulation be?
The ideal insulation thickness for your project will depend on the specific performance requirements you hope to fulfil and your target U-values. UK Building Regulations require around 100–150mm of rigid board insulation for most concrete slab floors.
What size insulation for a concrete floor?
Concrete floor insulation boards are normally 2400mm (L) x 1200mm (W), though sizes may vary slightly between manufacturers, so always check product datasheets. For example, Kingspan also offers 1250mm x 600mm XPS boards for concrete floor insulation.
The best way to know whether you have chosen the correct insulation size is to check the manufacturer’s recommendations for use. The product details will tell you if the product is compatible with your floor layout.
How to lay concrete floor insulation?
Begin by laying a damp-proof membrane (DPM). Follow this with the placement of the boards, positioning them close together. Seal all edges with tape if required, and then add a separating layer. Finish by pouring the concrete screed on top.
For above-slab systems, insulation sits beneath the screed layer; for below-slab systems, install insulation over the sub-base before the DPM.
