MFM Ultra HT Gains Class A Rating for WUI Roofing Applications

MFM Building Products has secured an additional Class A fire rating for its Ultra HT Wind & Water Seal roofing underlayment, expanding the product’s approved use in Wildland Urban Interface areas.

The Coshocton, Ohio-based manufacturer announced that the California State Fire Marshal has listed Ultra HT for use in W.U.I. zones when installed with Class A asphalt shingles. The approval falls under Listing No. 8180-2433:0001 in Category 8181 Non-Wood Roof Covering/Assemblies and meets applicable ASTM E108 requirements for Class A roof covering assemblies. W.U.I. areas represent zones where residential or commercial development meets undeveloped land or vegetative fuel sources, creating elevated wildfire exposure risks. Building product performance in these environments continues to receive increased scrutiny as wildfire activity intensifies across multiple regions of the U.S.

Ultra HT is a 45-mil self-adhered roofing underlayment designed for steep-slope roofing and re-roofing applications. The product incorporates a cross-laminated polyethylene top film with a traction surface intended to improve walkability during installation. Its high-temperature adhesive formulation is rated to 250°F for demanding roofing environments.

The new California State Fire Marshal approval adds to existing fire performance certifications for the product, including UL 790 and ASTM E108/ICC-ES AC188 compliance.

MuleHide Adds Sizes to Help Crews Speed Low-Slope Roof Installations

MuleHide has expanded its White-on-Black self-adhering EPDM and Poly ISO flat insulation lines with new sizes aimed at improving installation efficiency.

The White-on-Black SA EPDM membrane is now available in 5-by-40-foot rolls. Smaller and lighter than traditional rolls, the format is designed for easier handling in high-rise, residential and space-constrained projects. The self-adhering membrane eliminates the need for bonding adhesive, reducing installation time while maintaining EPDM durability and providing a reflective surface for improved energy efficiency.

Poly ISO flat insulation is now offered in 4x12-foot panels, extending beyond the standard 4x8-foot size. The larger panels reduce the number of boards, seams and fasteners required on certain mechanically attached systems, helping streamline installation on large commercial roofs. MuleHide reports improved crew productivity and lower labor and material costs.

The insulation panels are available in multiple thicknesses and feature dual facers to help manage application conditions in fully adhered systems.
