Details

Alpsam may be used in a low slope or dead flat application
Alpsam is certified by Underwriters Laboratories as meeting requirements of its Class A fire rating in various system configurations.
Alpsam has Factory Mutual approval for Class 1-90 with various insulations.
SRI Rating of 90.66
Alpsam requires no ballast. With the membrane weighing less than 1/2 lb. per square foot, minimal additions to present deck loads can be achieved using Alpsam.
Alpsam has been proven resistive to a wide range of chemicals, however, when roofs are exposed to harsh chemicals, a welded seam is always recommended. Consult with the Hyload Technical Department to determine which product to use for your specific application or to obtain a Chemical Resistance Chart.
Alpsam can be fully adhered to the substrate offering excellent resistance to wind uplift. Point stressing, which can occur with systems requiring mechanical fasteners to secure the membrane, is not a problem with Alpsam.
Alpsam‘s Elvaloy® sheet is manufactured without liquid plasticizers permitting the use of stronger more resilient raw materials and a unique bonding adhesive system. The membrane’s properties remain intact longer since plasticizer migration does not occur as is the case with many other Thermoplastic membranes which use liquid plasticizers.
