The Garland Company Inc. announced that its cold-applied Green-Lock® Membrane Adhesive has been approved for use as a flood coat in cold-applied modified-bitumen roofing applications. Use of the adhesive facilitates completely VOC-free roofing installations from the deck to the topcoat, the company says.
The company says independent testing has verified the membrane adhesive’s ability to meet Class A ASTM E108 fire test at a 3:12 slope. The adhesive was introduced in 2009.
The membrane adhesive is described as a high-performance asphalt-modified polyether adhesive used in the assembly of cold-process roofing systems. Its curing cycle is catalyzed by the moisture in the air, and is complete in one to five days, the company says. When used in conjunction with single or multiple plies of base sheets and membranes, the membrane adhesive is reported to create a high-performance, solvent-free modified-bitumen roof system.
Tom Stuewe, Garland product manager for coatings and adhesives, said the company’s Green-Lock line of high-performance adhesives is nearly odor free, minimizing any effects on building occupants even in sensitive applications such as schools, hospitals, or labs.
The membrane adhesive is recommended for use with two-ply modified-bitumen applications, and is approved for use with a variety of modified-bitumen base sheets, the company says.
