Installation and self-build overview

We supply SIP panels and shell kits. Most customers erect with their own builder. This page is general guidance — not a method statement or structural design.

SIP panel home extension walls going up on site

Before panels arrive

  • Foundations ready (slabs, piles or ground screws — we can quote StopDigging-style screws)
  • Access for delivery vehicle and unloading
  • Drawings / opening schedule agreed with your builder

Typical shell sequence

  1. Set sole plates / base detail per your design
  2. Stand wall SIP panels, join with splines and fixings
  3. Fit roof SIP panels; weather the roof covering (EPDM / metal — quote)
  4. Cut openings on site; fit windows and doors
  5. Clad externally; finish internally

We do not publish a full install manual on the site yet. Competent builders familiar with SIPs should lead. Ask if you want us to quote fitting.
