SIP Panel 142mm

Our SIP panels are manufactured with Sterling OSB3 for proven structural performance and enhanced moisture resistance. Paired with Celotex (or equivalent premium PIR), they deliver excellent thermal performance thanks to low thermal conductivity (λ) and dual foil facers that act as a vapour control layer—removing the need for additional membranes. Each panel is bonded with a high-strength two-part PU adhesive and pressed at 120 tonnes to ensure uniform integrity. Dimensional tolerances are typically 1–2 mm, with sub-1 mm precision available for projects that demand it.
