New Ideas

Adhesive is quick-drying

Mule-Hide Products Co. Inc. has made available AeroWeb Low-VOC Aerosol Contact Adhesive/Primer, a spray-applied adhesive that reportedly can be applied 60 percent faster than traditional roller-applied adhesives. Featuring a low-volatile organic compound (VOC), the adhesive can be applied in temperatures as cold as 25 F to help contractors avoid weather-related delays. The adhesive can be used to adhere standard TPO and EPDM membranes to horizontal and vertical surfaces; adhere fleece-backed membranes to vertical surfaces; and prime exposed asphalt before application of Mule-Hide Helix® Low-Rise Adhesive for insulation attachment. AeroWeb Low-VOC Aerosol Contact Adhesive/Primer is said to flash off in less than five minutes and remains sticky long enough for contractors to adhere large sections of membrane. The adhesive is available in a 30-pound cylinder capable of covering about 1,000 square feet when used as a contact adhesive.

Toolset enables accurate rooftop measurements

Nearmap has introduced a roof measurement toolset in the web-based application MapBrowser™ that allows users to measure roof slope, height, width and area using high-resolution oblique aerial images. The MapBrowser toolset reportedly helps reduce the number of on-site visits required during a project's quoting and planning stages while increasing the accuracy of material estimates. Users can view MapBrowser imagery through a standard web browser and annotate images with notes, drawings and measurements.

Underlayment requires fewer fasteners

McElroy Metal has made available HydraShell MAX and HydraShell Supreme SA underlayment. HydraShell MAX, a standard synthetic underlayment with four-layer construction, reportedly can be used under a variety of finished roofing materials, including steel. The underlayment can be used for roof slopes as low as 1/2:12 and reportedly requires fewer fasteners than similar products. HydraShell Supreme SA is a peel-and-stick underlayment said to be best suited for high-temperature, self-adhering applications; the underlayment's cool gray surface helps reduce heat buildup.

Shingles have smog-reducing granules

Malarkey Roofing Products® has made available Highlander® NEX™ laminated architectural shingles with 3M™ Smog-reducing Granules. Made with sustainable NEX polymer-modified asphalt for enhanced flexibility, the shingles reportedly resist tearing and nail pull-out and can withstand winds up to 110 mph. Smog-reducing Granules are integrated throughout the shingles' surfaces, where the granules' photocatalytic coating is activated by the sun's ultraviolet (UV) rays to help reduce smog. Highlander NEX shingles also feature 3M Cool Roofing Granules said to reflect UV rays to cool a building and reduce energy costs. Highlander NEX shingles are available in five colors: Heather, Natural Wood, Sienna Blend, Silverwood and Weathered Wood.

Tool limits silica dust exposure

DEWALT® has added the FLEXVOLT™ 60V MAX Dust Extractor to its DEWALT PERFORM & PROTECT™ line of tools intended to limit workers' exposure to respirable crystalline silica. Powered by DEWALT FLEXVOLT Batteries, the dust extractor is said to help contractors remain Occupational Safety and Health Administration-compliant on job sites. The FLEXVOLT 60V MAX Dust Extractor achieves 125 cubic feet per minute during concrete drilling and grinding or cutting up to 5-inch wheels. The dust extractor also features an automatic filter cleaning mechanism and Wireless Tool Control that gives a user the option to activate the tool from a few feet away using a remote.

Roof coating is silicone-infused

Nationwide Protective Coatings Manufacturers Inc. has added PERMASIL™ silicone-infused, acrylic roof coating to its PERMAPRODUCT™ line. The bright-white coating has a water-based formula said to protect and extend the lives of most roofing surfaces. PERMASIL's silicone technology reportedly increases waterproofing protection by sheeting off water from a dried coating surface.
