Spray Polyurethane Foam Locks a Roof into Place

Lapolla Industries Inc. has made available FOAM-LOK 2800-4G Spray Polyurethane Foam for roofing.

Lapolla Industries Inc. has made available FOAM-LOK 2800-4G Spray Polyurethane Foam for roofing. The fourth-generation SPF eliminates ozone depletion potential and reduces global warming potential. The rigid, closed-cell SPF may be applied over most new or retrofit roofing substrates. FOAM-LOK locks every portion of the roof into place, creating a monolithic membrane and eliminating the need for mechanical fasteners. The product seals the envelope, which minimizes the escape of conditioned air and dramatically reduces the structure’s energy consumption for heating and cooling, in turn reducing energy costs over the life of the roof. The low-maintenance material also resists wind uplift and acts as a waterproofing solution.

Lightweight Solar Panels Can Be Used On Flat Roofs

Beamreach Solar has introduced Sprint, a lightweight photovoltaic solar panel system for flat commercial roofs.

Beamreach Solar has introduced Sprint, a lightweight photovoltaic solar panel system for flat commercial roofs. Sprint can be installed on nearly all commercial roofs that cannot currently support heavy conventional solar systems, dramatically expanding the commercial solar power market. Featuring maximum power capacities ranging from 290 to 320 watts, Sprint integrates racking into the panel for quicker installation that requires no tools and no grounding. Sprint’s design also reduces the distance required between panel rows, enabling up to 30 percent more panels to be installed on a roof, increasing the solar system’s overall energy output. Sprint panels have been tested to support test loads up to 5,400 Pascals and withstand wind speeds of 115 mph. Sprint also comes with a 25-year linear output warranty and 10-year product warranty.

Engineered Cedar Is Lightweight and Strong

Ply Gem Roofing Engineered Cedar is made using a proprietary polymer formulation—with nearly 100 percent recycled resins—and laser-engraved into molds. It replicates the look of natural cedar roofing while offering a solid-core composition that is strong enough for roofers to walk on while installing. Engineered Cedar can be cut and scored with a utility knife, attached with a nail gun or nailed by hand, and requires no additional framing support or special skills for installation. The product is available in Weathered Gray and Warm Brown color families, which are blended in the factory for authentic variation. It is available in multiple widths to produce visually authentic installs.

Roof Is Standing-seam and Through-fastened

Lester Building Systems has launched its patented Eclipse Roof System.

Lester Building Systems has launched its patented Eclipse Roof System.

Lester Building Systems has launched its patented Eclipse Roof System that combines the structural integrity, efficiency and ease of installation of a through-fastened roof with the sleek appearance and leak-free performance of a standing-seam roof. The 36-inch-wide panels install quickly; one-third to one-half the number of panels and fewer screws are required than when using typical standing-seam roof panels. The 26-gauge Eclipse panel can be installed over open purlins; no roof deck is required.

Air and Vapor Barrier Creates a Seal Between a Low-slope Roofing System and the Building Below

F1 Air & Vapor Barrier from Mule-Hide Products Co.

F5 Air & Vapor Barrier from Mule-Hide Products Co.

F5 Air & Vapor Barrier from Mule-Hide Products Co. allows contractors to quickly and easily create an air- and vapor-tight seal between a low-slope roofing system and the building below.

F5 Air & Vapor Barrier is compatible with a wide variety of roofing systems and can be used on primed substrates, including concrete, plywood, exterior gypsum, DensDeck Prime and SECUROCK. It also can serve as a temporary roof for up to 120 days while work on the finished roofing system is completed.

The membrane is a 40 mil-thick composite consisting of 35 mils of self-adhering rubberized asphalt laminated to a 5 mil-thick woven polypropylene film. Rolls are 39 inches wide and 75 feet long and cover approximately 244 square feet of substrate surface.

F5 Air & Vapor Barrier’s factory-controlled thickness helps ensure that the membrane has uniform barrier properties, reducing moisture movement through the roofing system and helping keep conditioned air inside the building and unconditioned air outside. The woven polypropylene film makes the membrane highly resistant to tears and punctures. The non-skid surface helps keep contractors safe on the job site and is suitable for the bonding of subsequent layers of the roofing system.

A siliconized one-piece release liner prevents the material from bonding to itself in the roll and is easily removed during installation of the barrier.

Metal Panels Include Polyiso Core

Green Span Profiles has added RidgeLine, a patented 2 3/8-inch-tall mechanically seamed roofing panel, covering 42 inches, with thickness options of 2 1/2, 3, 4 and 5 inches.

Green Span Profiles has added RidgeLine, a patented 2 3/8-inch-tall mechanically seamed roofing panel, covering 42 inches, with thickness options of 2 1/2, 3, 4 and 5 inches. The core is a continuously poured-in-place, polyisocyanurate insulating foam. Exterior and interior metal panels are available in 26-, 24- and 22-gauge Galvalume/G90 galvanized and stainless steel. The exterior finish is standard gloss PVDF coating. RidgeLine panels can be used on slopes as low as 1/2:12 and are available in standard lengths, measuring 12 to 53 feet, with custom lengths available on demand. The panel offers nominal R-8 per inch of insulation thickness; R-20 for the 2 1/2-inch panel.

Reduce Roof Temperatures by as Much as 20 Percent

CertainTeed has strengthened its highly reflective, low-slope CoolStar roofing products with an enhanced ceramic granule surface.

CertainTeed has strengthened its highly reflective, low-slope CoolStar roofing products with an enhanced ceramic granule surface. The granulated, uncoated finish is designed to be a cost-effective way to lower commercial building energy consumption and increase occupant comfort. It handles like a standard roofing product without special installation requirements, is more aesthetically pleasing, and yet maintains a high solar reflectivity, reducing roof temperatures as much as 20 percent.

CoolStar products meet ENERGY STAR and California Title 24 requirements. CoolStar also qualifies for LEED points and meets NAHB National Green Building Standards.

CoolStar is designed to work with a wide range of roof systems, including built-up roofing, SBS, APP and self-adhering modified bitumen. It is extremely flexible and durable, because of the layering of high-quality reinforcements, heavy asphalt coating and highly reflective ceramic granules. This toughness combats the negative effects of natural expansion and contraction caused by heating, cooling, light and moisture. In addition, the brilliant white CoolStar surface is factory applied for hassle-free, one-step installation, which helps reduce labor costs.
