Higher Warranted R-values, Higher Performing Envelopes - Premier SIPS MAX with GPS Insulation Cores

Graphite Enhanced Structural Insulated Panels

Premier SIPS MAX are truly the epitome of high-performance offsite framing systems.  Made with GPS (graphite rigid insulation polystyrene) rigid insulation cores, Premier SIPS MAX offer 41% higher (warranted) R-values over stick-framed construction.

Premier SIPS MAX Power Up Design, Construction & Energy Efficiency

The Science Behind Graphite

Premier’s MAX SIPS are made with graphite polystyrene (GPS) cores which increase R-values through the graphite’s ability to reflect radiant heat like a mirror.  The result is a cost-effective way to increase R-values by an average 30%.  Ultimately Premier SIPS are able to increase energy efficiency without significant cost increases.

Higher Insulating Values: Graphite-insulated cores drive an increase in R-values even further the colder the temperature gets.  In fact, GPS SIPS MAX R-values actually increase in colder weather.

Higher Warranted R-values:  
Premier's SIP systems create tight building envelopes, which reduce heating and cooling (operating) costs regularly by up to 60%, and increase R-values an average of 41% over stick framing.  Additionally, the energy efficient envelope Graphite MAX SIPS create enable a reduction in mechanical (HVAC) equipment needs - often up to 1/3 in system sizes.

Thinner Framing:  In many conditions, higher R-values allow for thinner panels, which in turn can reduce accessories (shorter fasteners, thinner connection pieces) and transportation costs tied to the shipment of SIPS from the factory to the job site.

Environmentally Responsible:  Made from rapidly renewable wood species  (structural grade OSB facings), solid core rigid insulation that is manufactured in a steam (rather than chemicals) expansion process, Premier SIPS MAX contain no HBCDs or other harmful contaminants. Premier SIPS MAX are recyclable, starting with the GPS insulation core, extending to the outer OSB facings. The nature of factory fabrication, and optimizing raw materials enables SIPs projects to save 30% on jobsite construction waste over traditional construction further helping to reduce the burden on our natural resources.

Code Approved:  Premier SIPS MAX are recognized by key code approval agencies, easily meet energy code requirements, and notably are the only non-cement-based enclosure approved for California’s Title 24 new construction requirements.  SIPS MAX Graphite (GPS) cores are made with BASF’s Neopor which has earned GREENGUARD GOLD Certification.
