Free-flowing granules pour directly from the bag, filling tight, complex spaces inaccessible to standard glass wool or board insulation.
No cutting needed; creates a seamless, continuous heat-trapping surface.
Ultra-lightweight: Made of highly aerated particles with 90% air, enabling easy transport, handling, and lifting into lofts without stressing structural elements.
Permanently protects against fire, remains non-combustible and thermally stable up to 1300°C.
Decay and pest resistance: Its inert mineral makeup ensures long-term stability, preventing decomposition, deterioration, and attraction of insects and rodents.

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.
Full fill cavity wall tongue & groove PIR insulation. Fibre free insulation core with aluminium foil composite to both sides. Engineered jointing system for superior fit. Suitable for full fill cavity wall applications, whilst maintaining a residual 10mm cavity helping resist moisture transfer, aids installation and accommodate mortar squeeze.
