100mm Unilin Safe-R 019/CW Phenolic Partial Fill Cavity Insulation Board - 1200mm x 450mm (pack of 4)

100mm Unilin Safe-R 019/CW Phenolic Partial Fill Cavity Insulation Board is a high‑performance phenolic insulation panel designed for traditional masonry cavity walls. It delivers excellent thermal efficiency while preserving a clear residual cavity, helping protect buildings from wind‑driven rain. This makes it a strong choice for projects aiming to meet demanding U‑value requirements without increasing wall thickness unnecessarily. Safe‑R 019 (SR019/CW) is a rigid phenolic insulation board faced with composite foil on both sides. Its low declared thermal conductivity of 0.019 W/mK enables superior insulation performance at reduced thicknesses. The board is engineered specifically for partial‑fill cavity wall construction, the most common method in traditional masonry building.

APPLICATION

• Partial‑fill cavity walls in residential and commercial buildings
• New‑build masonry construction requiring improved thermal performance
• Projects targeting lower U‑values while maintaining a conventional wall width

CHARACTERISTICS

• Phenolic insulation core: Provides high thermal performance with enhanced fire characteristics.
• Maintains a clear residual cavity: Ensures continued protection against wind‑driven rain.
• Lower lambda value: Helps achieve improved U‑values without widening the wall build‑up.
• Foil‑faced on both sides: Enhances thermal efficiency and moisture resistance.
• Suitable for new build masonry walls: Ideal for traditional cavity wall construction where performance and space efficiency matter.
• Reaction to Fire: Euroclass D-s1, d0
