New Products

Johns Manville, a global building and specialty products manufacturer, has introduced several new products recently. ProtectoR™ HD High Density Polyiso Cover Board provides excellent protection and can save time and expense for contractors. With a closed cell polyiso foam core and inorganic coated glass facers, this high-density cover board has a Grade 1 compressive strength and an R-value of 2.5. The product offers excellent resistance to moisture, hail, wind uplift, and puncture, plus its light weight makes it easy to handle.

 

 

 

 

 

 

The product has the lowest fastening rates in the market for a HD polyiso cover board, meaning up to 50% fewer fasteners are needed to achieve FM I-90. As an example, it takes only eight fasteners per 4’ x 8’ board with adhered reinforced membrane applications over a minimum 22 gauge steel or structural concrete deck to achieve FM 1-90 performance.

Johns Manville has also introduced two new EPDM products. EPDM Tape Primer Plus features greatly improved coverage rates when compared to competitive products, specifically 500 sq.ft. per gallon vs. 250 sq.ft. per gallon for the competition. With a consistent smooth texture, the product is easier to mix and has superior tack-back performance. EPDM Tape Primer Plus also has an improved application temperature range above 25º F. EPDM FIT One-Sided Pre-Taped is an exciting addition to the Johns Manville factory inseam tape line, and is offered with 4” or 6” factory inseam tape, as well as 20’ and 30’ one-sided pre-taped sheets.

 

 

 

 

 

Johns Manville recently added 12’-wide TPO roofing sheets in all thicknesses, including 45, 60, and 80 mils. The wider roll makes many roofing jobs easier, with fewer lifts to the roof and labor savings from welding fewer laps. The company also produces a 6’-wide sheet.

 

 

 

 

 

 

TPO SA is a versatile flashing membrane that is perfect for curbs, corners, and parapet walls. It installs at a wide temperature range beginning at 20º F and rising on an approved substrate with primer, or direct to smooth approved substrate at 40º F and rising.
