By producing SIPs in-house rather than buying them in from bigger companies, we have full control over our supply chain and can pass on material costs savings direct to our clients. Transparency, from responsible sourcing to manufacture and installation, is something we care deeply about and we always aim to partner with suppliers and companies who share our environmental ethos.

Panel components

Our SIPs use 15mm Sterling Board OSB3 skins as standard. Sterling OSB3 is a precision-engineered structural board that is an industry recognised as a structural material for use in load-bearing conditions. Sterling OSB3 is BBA approved and conforms to Eurocodes. Sterling OSB3 is also FSC® certified and made from timber grown in the UK. It is manufactured here too, meaning fewer carbon miles are clocked up during transportation.

For the foam core of our SIPs we use 100 Grade EPS from Jablite – the UK’s largest producer of EPS products for the construction industry. EPS is non-toxic and biologically inert. Containing a flame-retardant additive, it has a reaction to Fire Class E, a high strength-to-weight ratio and very low thermal conductivity (W/mK, at 10°C) of 0.032.

We laminate the OSB3 skins and EPS foam together to form SIPs using polyurethane glue and leave to cure under pressure in our press. Polyurethane is incredibly strong and once cured, the three layers that get laminated together create a SIP panel that can withstand incredible stresses. To see just how strong SIPs can be under extreme pressures, we recommend you watch this short video clip from a testing facility in the United States.

Innovate and insulate

We’re working hard to become more and more self-sufficient as we grow operations and production at Ecologic. Our latest quest is to develop our own environmentally-friendly insulation. Company Founder Pete Samson is busy connecting with the sector’s most innovative suppliers, on a search for one that shares our vision for more sustainable building methods and materials.
