Asphalt Fabric Membrane","description":"\u003cp\u003eAsphalt fabric membrane is a narrow roll of reinforcing fabric used with asphalt roof cement, mastic or hot asphalt to build a reinforced repair or flashing detail. The fabric is embedded in a bed of cement and then covered with a second coat, so the cured patch has a fibrous core that resists splitting as the roof moves.\u003c\/p\u003e\n\u003cp\u003eThe narrow roll width suits linear work — seams, laps, curb and wall flashings, pipe penetrations and cracks — where a full-width sheet would be wasted. Fabric is cut to length from the roll, worked into the wet asphalt with a brush or trowel to remove air, and top-coated until the weave is fully saturated.\u003c\/p\u003e\n\u003cp\u003eIt is a repair and detailing material rather than a stand-alone membrane; it always works as part of an asphalt-based system and depends on full embedment to perform.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eOpen-weave reinforcing fabric supplied on a continuous roll for cutting to length\u003c\/li\u003e\n\u003cli\u003eNarrow width sized for seams, laps and flashing details\u003c\/li\u003e\n\u003cli\u003eEmbeds into asphalt roof cement, mastic or hot asphalt to form a reinforced patch\u003c\/li\u003e\n\u003cli\u003eFibrous core bridges cracks and distributes movement across the repair\u003c\/li\u003e\n\u003cli\u003eWeave allows asphalt to bleed through for a fully saturated, monolithic layer\u003c\/li\u003e\n\u003cli\u003eConforms to inside and outside corners and around penetrations when worked in with a brush\u003c\/li\u003e\n\u003cli\u003eSold by the roll for repeated small repairs without material waste\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eReinforcing asphalt cement repairs on low-slope and built-up roofs\u003c\/li\u003e\n\u003cli\u003eFlashing details at parapets, curbs and wall-to-roof transitions\u003c\/li\u003e\n\u003cli\u003eSealing around pipe, vent and penetration bases\u003c\/li\u003e\n\u003cli\u003eReinforcing seams and laps in roll roofing and modified bitumen work\u003c\/li\u003e\n\u003cli\u003eBridging cracks and splits in aged asphalt roof surfaces\u003c\/li\u003e\n\u003cli\u003ePatching gutter and metal-to-asphalt joints with roof cement\u003c\/li\u003e\n\u003cli\u003eReinforcing asphalt coatings over foundation and below-grade waterproofing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eProduct Details\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Asphalt reinforcing fabric membrane\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eForm:\u003c\/strong\u003e Roll\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRoll Width:\u003c\/strong\u003e 9 in.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRoll Length:\u003c\/strong\u003e 150 ft.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Embedded in asphalt roof cement, mastic or hot asphalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSold By:\u003c\/strong\u003e Roll\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable class=\"product-specs\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eDimensions\u003c\/th\u003e\n\u003ctd\u003e9\" x 150'\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"ARCH Building Supply","offers":[{"title":"Default Title","offer_id":55048724283731,"sku":"FM9","price":29.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1012\/7743\/4195\/files\/arch-placeholder-coming-soon_b6ec91b9-f168-40cb-87bd-a280a5dcfae7.webp?v=1790259797"}],"url":"https:\/\/arch-9365.myshopify.com\/collections\/roof-membranes-cap-sheets.oembed","provider":"ARCH","version":"1.0","type":"link"}
