About Us

ModulR TS Inc. was founded in 1998 to answer three major concerns that would eventually come to plague the North American roofing market. These three concerns were: The quality of roofing materials, a wave of labour shortages and liability.

Because of stone wool’s non-combustibility, its dimensional stability, its water repellent and sound absorbent qualities, ModulR has always believed in the unsurpassed quality of stone wool for roofing applications as both an insulation and excellent substrate for the membrane. ModulR invested years and millions of dollars in research and development, third party testing and certifications to bring new and innovative roofing solutions that would help address these three concerns facing the roofing industry.

Since 1998, we’ve been successfully designing tapered layouts and serving the tapered needs with tapered ROCKWOOL® Stone Wool. 

Pioneers in value-added Roxul Stone Wool, ModulR also offers ROCKWOOL® Stone Wool tapered backslope, pre-cut crickets, pre-cut sumps, cant and metal roof and metal deck flute filler.
