SIPs — Supplied & Installed

SIPs. High performance, supplied and installed.

Certified SIP panels, installed by our own teams, UK-wide.

SIPs Within a Timber-Led Selection

A fast, fabric-first envelope.

Structural insulated panels give a fast, fabric-first envelope, one route within our timber-led selection, chosen when speed and thermal performance are the priority. Delivered from design to weathertight, with the evidence planned before manufacture.

Why SIPs: When They're the Right Route

A high-performance envelope, fast.

SIPs give you weathertight in a fraction of traditional build time, with excellent thermal performance and minimal site waste. As a SIP panel supplier and installer, we select the panel range around your performance target, supply the certified panels and install them with our own teams, so what is specified is what gets built. Where SIPs are not the right route, we will say so.

  • Full panel range selected to your U-value target, no insulation top-up bolted on after.
  • BBA-certified panels as standard, or a specified alternative. We advise, it is your choice.
  • Digital design and structural engineering, aligned with your team.
  • Fire, acoustic and thermal evidence prepared for the project team.
  • Installed by our own CSCS / SSSTS qualified teams.

Why Offsite

Faster, greener, built to perform.

SIPs deliver a fabric-first envelope that is fast to weathertight and built to perform.

  • Speed: weathertight in days.
  • Energy: certified U-values in the panel from 0.12 W/m²K (see the range table on our Technical page), excellent airtightness, Eco to Passivhaus.
  • Sustainability: minimal site waste, lower embodied and operational carbon.
  • Certainty: factory-controlled, certified systems that satisfy Building Regs and major warranties.

  • Design: from your drawings we create detailed design-for-manufacture and assembly information.
  • Engineering: full structural engineering integrated with your professional team.
  • Supply: precision offsite manufacture of accredited systems, plus components, materials and fixings.
  • Logistics: delivery, offloading, cranes and lifting operations managed by us as standard.
  • Install: our own teams erect the frame in a planned sequence to the committed weathertight date.

Performance: Evidenced, Not Overclaimed

U-values delivered in the panel. Airtightness supported and evidenced.

The U-value is built into the panel and we hand you the certified value. Airtightness is a whole-team result. We provide accredited junction details, thermal modelling and a QA-audited install, and support you to the test, but we will not pretend the tested result is ours alone to guarantee. That honesty is rarer than it should be.
