Excellent thermal performance with a thermal conductivity of 0.022 W/m.K, reducing the thickness of insulation required to hit the target U-value.
Low emissivity foil facing provides improved thermal performance in sealed cavity air spaces, improving the achievable U-value.
Soprema boards are light and rigid assisting with ease of transportation, handling and fitting.
Sopratherm XR4000 has been assessed by the BBA as fit for use in defined roof, wall and floor applications if installed, used and maintained as set out in the certificate. Please read the certification at insulation-UK.com/

Actis Hybris Panels are 1.2m in length, 114.5 cm in width, and have a thickness of 15.5cm, providing a total coverage area of 2.74m2.
Made of shaped polyethylene foam bonded to aluminium-coated films, their honeycomb structure with low-emissivity cavities provides high thermal efficiency. Heat capacity is 2300JK/kgK. Suitable for timber frames, masonry, pitched roofs, ceilings, and floors. Lightweight with tensile strength over 45kPa, tested to EN 1608 and EN 12310-1, durability maintained after ageing.
ckwool Sound Insulation Slab, measuring 1.2m x 60cm x 10cm, covers 4.32m2. Designed for internal walls and floors, it reduces noise between rooms and neighbouring properties, while offering excellent fire resistance. Made from stone, its dense, open-porous structure absorbs sound and prevents vibrations. Non-combustible, it withstands temperatures up to 1,000C, serving as a fire barrier to enhance safety and protect property.
TLX Multifoil Pitched Roof Insulation Gold: 10 m long, 1.2 m wide, 3.3 cm thick, covering 12 m2. A dual-function breather membrane that vapour vents and insulates like PIR, enhancing thermal performance without condensation or roof height changes. Suitable for refurbishments and new builds, preventing condensation and improving insulation. SD intelligent technology increases ventilation with moisture, removing the need for a vapour barrier. Lightweight, easy to install, with BBA certification and LABC approval. Ideal for historic, public, and social housing, barn conversions, new builds, and extensions.
This Knauf Insulation Loft Roll 44 Combi Cut Short Length has a thickness of 20cm, providing a total coverage area of 5.501m2. Loft Roll 44 is an A1 non-combustible glass mineral wool roll, manufactured using Knauf Insulation's unique ECOSE Technology and designed specifically for use in cold lofts where pitched roofs are insulated at ceiling level.
