The slim, lightweight design of the Sarnathin-50 Roof System decreases costs of building modifications and structural retrofits, while creating more usable space for living and/or operations.

CANTON, Mass. (PRWEB) March 21, 2018 -- Sika Sarnafil, the worldwide market leader in thermoplastic roofing and waterproofing membranes, is pleased to partner with R-50 Systems, LLC in announcing the release of the Sarnathin-50 Roof System, an innovative high R-value roofing system for non-residential building applications.

The Sarnathin-50 system utilizes Sika’s proven Sarnafil® roofing membrane in conjunction with R-50 Systems’ Rich-E-Board™, a 1.5-inch thick, vacuum-sealed insulation with a protective covering on both sides and an R-value (resistance to heat flow) of 50. The slim, lightweight design decreases costs of building modifications and structural retrofits, while creating more usable space for living and/or operations. Because Rich-E-Board can be produced to various dimensions, it can be used in most building and wall applications with little wasted material.

“This is an exciting new system offering for us,” said Bill Bellico, Director of Marketing at Sika Sarnafil. “The high thermal performance of the Rich-E-Board at such a thin build up, in conjunction with the long lasting performance of our Sarnafil roof membrane, offers a cutting edge solution that reduces costs of retrofitting roofs of existing buildings to meet modern building codes.”

While conventional insulation can require a thickness of 10 inches or more to reach an R-value of 50, Rich-E- Board achieves the same result at just 1.5 inches thick. Not only is Rich-E-Board mold and fire resistant, but it can also be installed on most roof deck types This innovative system delivers significant advantages to architects, contractors and building owners:

  • Proven performer – Actual performance in the field over time is the only true test of a roofing system’s quality. Billions of square feet of Sarnafil membrane have performed with distinction over the past 50 years in climates of every description.
  • Lower energy bills – Achieving an R-value of 50 can cut a building’s heating and cooling costs by 8 to 10 percent, according to an independent study done by Oak Ridge National
  • Simpler retrofits – Rich-E-Board enables retrofitted structures to achieve required R-values in less time, with fewer materials, and without costly and destructive building modifications when door thresholds, glazing, equipment and other elements limit the available height or thickness for new
  • Reduced construction costs – Rich-E-Board can be designed to different dimensions and is lightweight — it lowers the cost of delivery and handling and reduces insulation-related labor costs by more than
  • Design flexibility – With an incredibly slim profile – especially compared with multi-layer insulation – Rich- E-Board saves space, expanding the design options for

“Sika is a highly respected company that shares R-50’s vision for innovation and sustainability,” said Sheri Pettoni, VP of Marketing at R-50. “It has already proven to be a valuable partnership. Rich-E-Board and the Sarnathin-50 Roof System are creating a game-changing alternative. This combined effort fills a significant void in the marketplace by providing an insulation system capable of maximizing building envelop defficiencies and meeting today’s toughest energy standards.”

R-50 Systems, based in Kennett Square, Pennsylvania, develops innovative high R-value insulation products for the federal government and commercial/industrial marketplace.
