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.

You may return most new, unopened items within 30 days of delivery for a full refund. We'll also pay the return shipping costs if the return is a result of our error (you received an incorrect or defective item, etc.).
You should expect to receive your refund within four weeks of giving your package to the return shipper, however, in many cases you will receive a refund more quickly. This time period includes the transit time for us to receive your return from the shipper (5 to 10 business days), the time it takes us to process your return once we receive it (3 to 5 business days), and the time it takes your bank to process our refund request (5 to 10 business days).
If you need to return an item, simply login to your account, view the order using the "Complete Orders" link under the My Account menu and click the Return Item(s) button. We'll notify you via e-mail of your refund once we've received and processed the returned item.
We can ship to virtually any address in the world. Note that there are restrictions on some products, and some products cannot be shipped to international destinations.
