New Platinum Graphite-Infused Polystyrene (GPS)

Posted on

WEST-ECO introduces the next generation of SIPs made with Insulfoam’s Platinum graphite polystyrene (GPS) insulation. GPS is a class of insulation made with BASF’s Neopor, a rigid foam that integrates graphite into the polymer matrix. The graphite reflects radiant heat energy like a mirror, increasing the material’s resistance to the flow of heat – or R-Value. Testing has shown Platinum cores increase the panel’s overall R-Value by over 20 percent. Platinum core SIPs are used in building enclosures which need stable R-values – which increase as the temperature decreases. In some cases, Platinum panels, with GPS cores, can result in the need for a thinner panel while still meeting energy code requirements. This can also reduce freight costs and the size and thickness of accessories such as fasteners and lumber.

Passive Design is becoming more popular now than ever before in North America. Europe adopted this system of building Ultra Energy Efficient homes several years ago and now Passive Design is more the rule in Europe opposed to the exception.

WEST-ECO has had the privilege of working with the Architects, Energy Consultants, Contractors and Homeowners to create special connection details and designs in order to acheive maximum energy efficient results as well as to supply the pre- cut and ready to assemble SIPS for many Passive House projects this past year.

This project shown consists a beautiful Douglas Fir Timber Frame structure with 12″ EPS SIP walls with 12″ Graphite Polystyrene (GPS) roof panels for maximum R Value. The GPS provides 20% more R Value in the same panel thickness when compared to standard EPS by simply infusing Graphite to the standard EPS.
Special connection details were created and adopted by WEST-ECO to insure that this home would be completely air tight with ZERO thermal bridging and free of any penetrations through the SIP Panels.
SIP Panels provide an excellent alternative to conventional stick framing methods for Wall and Roof Assemblies for many types of structures. SIPs always provide a tighter and more energy efficient solution than any other type of wall or roof system while still keeping things SIMPLE to construct and with minimal waste. Typical SIP connection details, while less complicated than those used for Passive Design, still provide zero air infiltration within the splines and panels with very little thermal bridging.
