Berry Plastics Co., makers of the TYPAR Weather Protection System, recently launched Surround VR Underlayment, a synthetic roofing underlayment that reduces the amount and weight of material needed for roofing jobs. One roll of Surround VR covers the same area as five rolls of 30-pound felt, yet weighs seven times less. The waterproof product, which was developed for shingles, shakes, tile, slate and metal roofs, performs in temperatures ranging from -40 to 240 F. In cold temperatures, the material will not crack or wrinkle, which helps ensure smooth installs. In warm temperatures, its heat-reflecting, gray-colored surface reduces heat buildup on the roof. Surround VR withstands up to six months’ exposure to UV light, as well as high winds and storms experienced by coastal regions.

Synthetic Underlayment Is Approved for New and Reroofing Applications

Summit 180 synthetic underlayment by Atlas Roofing offers many advanced benefits not available with conventional felt.

Summit 180 synthetic underlayment by Atlas Roofing offers many advanced benefits not available with conventional felt.

Roof underlayment is the last line of defense that protects a home from serious damage if a roof covering is blown off or damaged in a storm. Summit 180 synthetic underlayment by Atlas Roofing offers many advanced benefits not available with conventional felt. It is an approved underlayment for new and reroofing applications and can be used with most types of code-approved steep-slope roof coverings, including metal.

On certain roof projects, underlayment may face a long exposure time from the dry-in to the completed roof covering. Atlas developed Summit 180 with performance characteristics that ensure its reliability during extended uncovered exposure to damaging UV rays. This lightweight, extremely strong, polypropylene fabric contains UV and water-resistant coatings that allow for up to 180 days of open exposure before being covered.

Summit 180 can withstand extreme temperatures from -40 F to 240 F. Unlike conventional saturated felt, Summit 180 is not prone to wrinkling or buckling. This allows it to lie more flat, which helps a roof protect against invasion from water.

Roofing crews benefit from a textured, wrinkle-free top surface and a slip-resistant coating applied to the face and base surfaces of this underlayment. This dial coating slip resistance provides improved grip to allow safer walkability during installation.

Summit 180 synthetic underlayment exceeds ASTM D226 Type I and Type II, the standard specification for asphalt saturated felt. It has earned ASTM D6757, the inorganic shingle underlayment standard. It is also UL 790 compliant for fire resistance.

Summit 180 roof underlayment is packaged for convenience in 10 square rolls weighing approximately 30 pounds each. For more details on Atlas Roofing’s synthetic underlayment, contact an Atlas sales representative.

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.

Underlayments Can Be Exposed for Up to Six Months

National Nail has expanded its STINGER line of roofing products with three ICC-certified synthetic underlayments: EXO50, EXO35 and EXO25.

National Nail has expanded its STINGER line of roofing products with three ICC-certified synthetic underlayments: EXO50, EXO35 and EXO25. The underlayments are UV-resistant and can be exposed for up to six months. The synthetic woven fabrics offer high tear strength, and proprietary non-skid additives provide better roof deck contact for high slip resistance. Each roll is lightweight and, with 10 squares per roll, fewer rolls need to be carried to the roof. In addition, preprinted nailing patterns and overlap lines speed installation. STINGER cap fasteners (StaplePac and NailPac) and STINGER cap hammers, cap staplers, and cap nailers are recommended for installing all STINGER EXO products.

Insulation Can Act as Standalone Underlayment

Environmentally Safe Products Inc.’s Therma Sheet roofing underlayment has been certified by the International Code Council Evaluation Service. The designation means Therma Sheet meets the code requirements of a standalone roofing underlayment for the building industry. Previously, code required roofers to install Therma Sheet over a layer of felt paper or another underlayment. Therma Sheet insulation is constructed of 99 percent pure polished aluminum facings, heat laminated to a closed-cell polyethylene foam core. This patented process makes Therma Sheet a thermal and moisture barrier under metal roofing, stone-coated steel, concrete, clay tile and more.

Synthetic Underlayment Provides More Coverage per Roll than Traditional Felt

Atlas Roofing, a producer of felt underlayment, produces a lightweight, synthetic alternative to organic felt known as Summit 60.

Atlas Roofing, a producer of felt underlayment, produces a lightweight, synthetic alternative to organic felt known as Summit 60. This underlayment, manufactured from strong woven polypropylene fabric, offers advanced benefits not available with traditional felt.

Summit 60 Synthetic Underlayment, which has high-temperature stability and offers greater resistance to UV breakdown than felt, has the durability needed for jobs that have a long open time from the dry-in to the completed roof covering. On certain steep-slope roof projects, underlayment can sometimes face such exposure for up to 60 days. For these roofing projects, underlayment must be able to maintain its reliability; Summit 60 meets these demands.

Roofing crews will appreciate that Summit 60 has a textured wrinkle-free top surface fabric and a slip-resistant polymer coating applied to its bottom surface, for safer walkability during installation. This slip-resistant polymer provides improved grip for reduced slippage between the underlayment and the roof sheathing.

Installation is easier because Summit 60 is manufactured with pre-printed lay lines. This water-resistant underlayment is packaged in 10 square rolls, each weighing less than 30 pounds. It provides more coverage per roll than traditional felt.

Summit 60 Synthetic Underlayment can be mechanically fastened to many different types of substrate, making it a solid underlayment choice for both new and re-roofing applications. This excellent synthetic product can be used with asphalt shingles, clay and concrete tiles, slate, and wood shakes, or any other code-approved steep slope roof covering.

Summit 60 underlayment has earned ASTM D6757, the inorganic shingle underlayment rating standard. Its performance exceeds ASTM D226 Type I and Type II, the standard specification for asphalt saturated felt and it is UL Classified as demonstrating conformance to critical fire testing requirements for a prepared roofing accessory. It also received FL 16226, the Florida Building Code approval.

Designed to enhance the life of a roof, Summit 60 qualifies as an Atlas Signature Select Roofing System component. Atlas Signature Select Roofing Systems are offered at three system levels allowing contractors to target all market segments.
