Structurally Insulated Panel (SIP) build system

SIP Panels: Strong, Smart, Sustainable
Structural Insulated Panels (SIPs) are an advanced building solution designed for maximum efficiency and sustainability.  As a Modern Method of Construction (MMC), they enable faster builds, reduced costs, and consistently high-quality results. Each panel is crafted from two layers of structural-grade OSB/3 with an insulation core of either EPS (Expanded Polystyrene) or PU (Polyurethane).

Why Choose SIPs?

  • Low-Carbon Building – SIPs support sustainable construction and help accelerate the path to net zero.
  • Superior Performance – A proven alternative to traditional construction methods, offering excellent thermal efficiency and airtightness.
  • Cost & Time Savings – Faster installation, slimmer wall profiles, and fewer materials mean reduced overall project costs.
  • Tried & Tested – With over 60 years of use worldwide, SIPs are a reliable and trusted building system.
  • Future-Ready – Recognised as a solution to rising material costs, stricter building regulations, and the demand for lower-energy homes and buildings.
