With its origins as a roofing contracting business, Polyglass became a leading manufacturer of modified roofing membranes in Europe in the 1960s and introduced its products and technology to the United States in 1992. Since then, Polyglass has grown to be a leading innovator in the roofing industry.
As the company continued its growth, it was acquired in 2008 by Mapei, a global manufacturer of adhesives, sealants and chemical products for the building industry. Since the acquisition, Polyglass U.S.A.'s headquarters moved to Deerfield Beach, Florida and the company continues to realize significant product development and company growth.

          A.Install modified bitumen membranes and flashings in accordance with manufacturer's instructions and with the recommendations provided by the National Roofing Contractors Association's Roofing and Waterproofing Manual, the Asphalt Roofing Manufacturers Association, and applicable codes.
 
          B.General: Do not installing modified bitumen membranes at temperatures lower than 40 to 45 degrees F (4 to 7 degrees C) wherever practicable. Where work is unavoidable at such temperatures the following precautions be taken:
          1.Take extra care during cold weather installation at ambient temperatures of 40 to 45 degrees F (4 to 7 degrees C) or below and when ambient temperatures are affected by wind or humidity, to ensure adequate bonding is achieved between the surfaces to be joined. This applies to both material seam welds and adhesion of the applied product to the appropriately prepared substrate as the substrate can be affected by such temperature constraints as well.
          2.In addition, unrolling of cold materials, under very low ambient conditions must be avoided to prevent the likelihood of unnecessary stress cracking. Rolls must be at least 40 degrees F (4 degrees C) at the time of application. Should the membrane roll become stiff or difficult to install, it should be replaced with a new roll from the heated storage area.
 
          C.Commence installation of the roofing system at the lowest point of the roof (or roof area), working up the slope toward the highest point. Lap sheets shingle fashion so as to constantly shed water.
 
          D.Base and Ply Sheet Installation:
          1.Install in a manner approved for the specific product, e.g. fully adhered as self-adhered or with asphalt adhesive, torch applied or mechanically attached.
          2.Base or Inter-ply side laps are to be 3 inch (76 mm) minimum and usually delineated by a "lay line" for mopped, torch or mechanically attached application. End laps are typically 6 inches (152 mm) in all cases.
          ** NOTE TO SPECIFIER ** Edit the following three paragraphs as required to include the installation type required for the roofing materials specified.
 
          E.Self-Adhered Application: Base or ply sheet shall be installed per Polyglass specifications and installation guidelines appropriate for the specific substrate type and thickness.
 
          F.Torch Application: The use of shielded "Dragon-wagons", or moveable, flame-resistant wind shields are recommended to keep all surfaces and materials at a suitably warm temperature during torch application.
 
          G.Mop Application: Asphalt handling equipment should be insulated in order to minimize the drop in asphalt temperature.
          1.Asphalt must be at least 400 degrees F (204 degrees C) with a target temperature of 425 degrees F (218 degrees C) or 20 degrees F (11 degrees C) above the EVT (equiviscous temperature), whichever is higher, at the point of application.
          2.If minimum asphalt temperature of 400 degrees F (204 degrees C) cannot be maintained at the point of application, work should be discontinued.

          4.Nailers and flashings should be fastened in accordance with Factory Mutual "Loss Prevention Data Sheet 1-49, Perimeter Flashing" and be designed to be capable of resisting a minimum force of 200 lbs/lineal foot (298 kg per m) in any direction.
 
          K.Metal Work: Provide metal flashings, counter flashings, parapet coping caps and thru-wall flashings as specified in Section 07 62 00 - Sheet Metal Flashing and Trim or Section 07 71 13 - Manufactured Copings.
