Accredited. Integrated. Built to Perform
Structural Insulated Panels (SIPs) are one of the most effective systems available for delivering high performance, low energy buildings when they are designed, co-ordinated and installed correctly.
Proven SIPs Delivery Expertise
Our specialist offsite division brings together:
Accredited, mortgageable SIPs systems
In-house installation teams with MMC experience
Digital design coordination to manage interfaces
Clear responsibility
This integrated approach reduces risk, avoids common site issues and ensures SIPs perform as intended in reality, not just in theory.
What Are SIPs?
Structural Insulated Panels (SIPs) are a factory manufactured building system with a rigid insulation core bonded between structural facings.
When correctly delivered, SIPs provide:
✅ Highly insulated building envelopes
✅ Excellent airtightness
✅ Rapid and predictable construction
✅ Lightweight structures
SIPs is not new!
Originally developed in the 1930s, SIPs are now widely used to form high-performance wall and roof structures across residential, education and commercial buildings.
SIPs Delivered as Part of the Whole Build
We focus on the integration of SIPs, not isolated installation.
We manage the critical interfaces that determine success, including:
Foundation tolerances and load paths
Window and door installation
Airtightness continuity
Co-ordination with heating and ventilation systems
By controlling these interfaces, we protect performance and avoid the costly issues that undermine many SIPs projects.
