Architects are continually challenged to achieve lower U‑values, slimmer build‑ups, and long‑term performance without compromising structural integrity. Polyfoam XPS has responded.
Our newly enhanced lambda values for Polyfoam Floorboard and Roofboard Extra give specifiers even greater design flexibility – enabling thinner constructions, improved thermal performance, and more efficient detailing across a wide range of applications.
Both products are BBA certified and manufactured in the UK by Polyfoam XPS Limited, ensuring dependable quality, proven durability, and reliable supply.
Why the improved lambda matters
Recent updates to our manufacturing process mean Polyfoam XPS now meets the growing demand for better U‑values with reduced thickness, supporting architects working on:
- Inverted roofs
- Ground floors and heavy‑duty commercial slabs
- Basements and below‑ground structures
- Car parks and podium decks
As highlighted in our latest technical update, “Polyfoam XPS meets demand for thinner insulation and better U‑values”, the enhanced thermal performance helps streamline build‑ups while maintaining the compressive strength and moisture resistance XPS is known for.
Trusted performance – backed by certification
- BBA certified for Floorboard and Roofboard Extra
- Made in the UK for consistent quality and shorter lead times
- Robust compressive strength for demanding load‑bearing applications
- Exceptional moisture resistance for long‑term thermal stability
