SIPit‑FR: REI 60/60/60 Fire‑Rated Panels for Boundary Walls & Party Walls

SIPit‑FR is a next‑generation structural insulated fire panel engineered for high‑risk wall applications in residential and multi‑residential buildings. Tested to BS EN 1365‑1, the panel delivers a certified REI 60/60/60 fire rating — meaning loadbearing strength (R), integrity (E), and insulation (I) are all maintained for a full 60 minutes, with fire resistance proven from both sides.

Where SIPit‑FR Is Used

• Boundary walls close to neighbouring properties

• Party walls between apartments or attached dwellings

• Any wall requiring a certified 60‑minute fire rating

These applications demand predictable fire performance, structural stability, and minimal heat transfer — all areas where SIPit‑FR excels.

Key Advantages

• REI 60/60/60 performance in a single factory‑made panel

• A1‑rated CMC facings for fully non‑combustible wall surfaces

• Structural loadbearing capacity built into the panel

• High‑performance thermal insulation

• Faster installation than multi‑layer fire‑rated systems

• Reduced risk of installation error and simpler inspection

SIPit‑FR replaces complex build‑ups of plasterboard, mineral wool, membranes, battens, and cladding with one integrated, compliant solution.

Why SIPit‑FR Matters for Boundary Walls

Boundary walls are notoriously difficult to build when space is tight or access is restricted. SIPit‑FR solves this by allowing direct application of spray cork render to the external face — eliminating the need for:

• Ventilated cavities

• Cavity barriers

• Fire‑rated membranes

• Battens and counter‑battens

• A1‑rated cladding systems

This makes SIPit‑FR one of the simplest and most compliant boundary wall solutions available in the UK today.
