90mm 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

CERTIFICATION

  • ISO 45001:2023+A1:2024 Occupational Health & Safety Management Systems
  • ISO 9001:2015+A1:2024 Quality Management Systems
