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

SIPit‑FR is a structural insulated fire panel designed for high‑risk wall applications in residential buildings. It provides a fully tested REI 60/60/60 rating under BS EN 1365‑1, with fire resistance proven from both sides.

Where it’s used

• Boundary walls close to site boundaries or neighbouring properties

• Party walls between apartments or attached dwellings

• Any wall requiring 60‑minute structural fire resistance

Key advantages

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

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

• Structural loadbearing capacity

• Thermal insulation built in

• Faster installation than multi‑layer fire‑rated build‑ups

• Reduced risk of installation error and easier inspection

  
  

Why it matters

Boundary and party walls must prevent fire spread, maintain structural stability, and limit heat transfer for a full hour. SIPit‑FR delivers this without relying on multiple layers of plasterboard, mineral wool, or complex on‑site sequencing.

When boundary walls are difficult to build in close proximity to the neighbouring property the SIPit-FR is easier to install. In combination with the spray cork render there is no need for ventilated cavities, cavity barriers, fire rated membranes, battens and counter battens, or A1 rated cladding. The panel is installed with the cork render directly onto the external face eliminating the problems associated with boundary wall construction.
