Unilin (previously Xtratherm) Under Floor Insulation Boards - when installed within a floor structure, will significantly improve the U-value of new or existing floors.
Thin-R Underfloor XT/UF has high compressive strength and closed cell structure, it provides high moisture resistance which makes it the ultimate solution for insulating floors.
It is also suitable for underfloor heating and use in pitched roofs.
Unilin (previously Xtratherm) Floor Insulation Key features:
- High Compressive Strength
- Suitable for Underfloor Heating
- Also suitable for pitched roofs
- Perimeter Strips for Robust Detailing
- Reduced Insulation Thickness
- Low Emissivity Foil Facings
- 2.4 metres x 1.2 metres (8 feet x 4 feet)
The floor in any building is an area of considerable downward heat loss when not properly insulated. XT/UF will significantly improve the U-value of new and existing floors.
Thin-R Underfloor XT/UF is lightweight, easy to install and combines high compressive strength with low thermal conductivity, providing a high performance solution for floor insulation.
Thermal conductivity is 0.022 W/m²·k (BS EN 13165:2008)

In an era of ever-rising energy costs and increased environmental consciousness, the significance of effective insulation cannot be overstated.
Among the various insulation options available, insulation boards have emerged as a popular choice due to their exceptional thermal and acoustic properties.
These versatile panels offer a myriad of benefits, from energy efficiency and cost savings to improved comfort and reduced environmental impact.
Benefits of Insulation Boards:
- Enhanced Energy Efficiency Insulation boards reduce heat transfer, helping maintain consistent indoor temperatures. This reduces reliance on heating and cooling systems, resulting in energy savings and a smaller carbon footprint.
- Improved Acoustic Insulation These boards also reduce sound transmission, providing a quieter environment, which is especially useful in offices, bedrooms, and recording studios.
- Moisture Resistance Moisture-resistant insulation boards prevent condensation and mold growth, reducing the risk of structural damage in humid or damp areas.
- Space Efficiency With a thinner profile than traditional insulation, these boards are ideal for retrofitting buildings or areas where space is limited.
- Versatility in Application
Available in various types and densities, insulation boards can be applied to roofs, walls, floors, and ceilings, and tailored for specific project needs.
Installing Insulation Boards: Step-by-Step Guide
- Gather Supplies Ensure you have insulation boards, adhesive, cutting tools, measuring tape, and safety equipment like gloves, goggles, and a mask.
- Prepare the Surface Clean and dry the surface where the boards will be installed.
- Measure and Cut Measure the area and cut the boards to size using a utility knife, following the manufacturer’s guidelines.
- Apply Adhesive Apply the appropriate adhesive to the back of the boards, based on the surface and manufacturer recommendations.
- Install the Boards Press the adhesive side against the surface, ensuring it's aligned and securely attached.
- Seal the Joints Seal gaps between boards with a suitable sealant to prevent air leakage and improve insulation effectiveness.
- Finish the Surface Finish with drywall, cladding, or another covering as needed.
Insulation boards offer a smart solution for improving energy efficiency, acoustics, and moisture control in homes and buildings.
Their versatility, space-saving features, and proper installation can enhance comfort and sustainability in any project.
