ROXUL Inc. announced a strategic partnership with Carlisle Construction Materials, a manufacturer of commercial roofing materials. This partnership will introduce new and innovative commercial roofing systems to the North American market.

Featuring a hybrid approach to roofing insulation, these new systems will include the option of a limited thermal warranty, which will provide a guarantee of the insulation R-values for the duration of the roofing system warranty up to 30 years. 

Carlisle roofing warranty programs, featuring EPDM and TPO membranes, will now include ROXUL stone wool roof insulation. Products that will be included in the warranty program include TOPROCK DD roofing insulation with integrated insulating coverboard and MONOBOARD insulating coverboard, as well as bitumen coated variations of both of these board products for Carlisle's Hot-Mopped systems with FleeceBACK AFX membranes.

“Energy efficiency and fire safety are huge issues today and will only become more important in the future. Stone wool roof insulation, used in a hybrid assembly, adds to the performance of polyisocyanurate and EPS (expanded polystyrene), which are two well-known insulation materials,” said Brian Le Voguer, vice president, Building Envelope for ROXUL Inc. in North America. “The partnership of ROXUL and Carlisle brings to the design community the confidence of working with two global leaders.”

“Carlisle is pleased to include TOPROCK DD and MONOBOARD stone wool insulation in our warranty programs," Steve Schwar, Director, National Sales for CCM said. "It will add options for designers and building owners interested in energy efficiency and fire safety."
