SIPit-BIO
94% Reused & renewable materials
Create a carbon negative footprint with SIPit-BIO
SIP is inherently sustainable in its approach to construction, but to
exceed the demands of the industry we have worked with our
suppliers to create a Polyurethane that has the same physical properties and performance of standard PU SIP but with the added
credentials of a certified sustainable upgrade.

SIPit-BIO is an advanced upgrade to the traditional PU SIP (Structural Insulated Panel) system, designed with sustainability and performance in mind. Comprising 94% recycled, reused, and renewable materials, SIPit-BIO redefines eco-efficient construction by combining high structural integrity with a dramatically reduced environmental footprint. This next-generation panel delivers the same strength, insulation, and versatility expected from premium SIP systems—while supporting a circular, low-carbon building future.
Benefits of SIPit-BIO
A new generation of PU foams is emerging.
Polyurethane has always been a high‑performance insulation material: low thermal conductivity, excellent dimensional stability, and strong compatibility with SIP manufacturing. What’s changing is the carbon source behind the chemistry. Instead of relying solely on fossil‑derived polyols, manufacturers can now incorporate renewable, bio‑based polyols produced from plant oils, agricultural by‑products, and circular waste streams.
This shift doesn’t alter the core performance of PU — it changes the origin of the carbon embedded in the polymer.
♻️ Why bio‑based PU matters for SIPs
Bio‑based PU aligns perfectly with the sustainability priorities of modern construction:
-
Lower embodied carbon
-
Replacing fossil polyols with renewable carbon reduces the cradle‑to‑gate footprint of the foam.
-
No compromise on performance
-
Thermal conductivity, compressive strength, dimensional stability, and adhesion remain equivalent to conventional PU — critical for SIP structural integrity.
-
Supports circular and renewable‑carbon strategies
“SIPit uses polyurethane systems that incorporate renewable, bio‑based polyols — reducing fossil carbon in our insulation without compromising the exceptional thermal performance that defines SIP construction. This is part of our wider commitment to responsible manufacturing, transparent carbon reporting, and continuous improvement in material sustainability.”
