Details

Hyload WS may be used in a low slope or dead flat application.
Hyload WS is certified by Underwriters Laboratories as meeting requirements of its Class A fire rating in various system configurations and has Factory Mutual approval for Class 1-90 with various insulations.
Hyload WS is UV stable.
Hyload WS 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 Hyload WS.
Hyload WS has been proven resistive to a wide range of chemicals, however, when roofs are exposed to harsh chemicals, a welded seam is always recommended.
Hyload WS 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 Hyload WS.
Hyload WS 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.
It is designed to be installed with various hot or cold applied adhesives.
Laps are sealed with the selected adhesive in top pour and aggregate applications or by hot air welding when a smooth or coated finish surface is required.
