Veral
The Stunning Metal Clad System Combining Design, Flexibility, and High Performance Protection
-
Whether it's energy efficient aluminum, chemical resistant stainless steel, or rich copper, Veral's foil-faced surface lends a dramatic look to any project.
-
Siplast Veral utilizes the time-proven waterproofing characteristics of SBS-modified asphalt, the stability and strength of glass fiber, and the protective qualities of metal foil. This combination creates a membrane that is tough, lightweight, long-lasting, and weathertight.
-
The Siplast Veral System is composed of two sheet components, Irex and Veral. Irex is the base ply, consisting of a quality high-melt asphalt with a fiberglass reinforcement. The finish ply, Veral, combines a glass scrim-reinforced SBS-modified asphalt base with a protective foil facing.
-
-
Because metal and asphaltic materials expand at different rates, special features have been engineered into Veral's design. Using a patented embossing system, small control channels are built into the metal facing. A thin layer of low-melt asphalt is factory applied beneath these channels, allowing the metal to expand and contract independently of the modified asphalt base. Over forty years of successful roofing and flashing experience prove that Veral's patented design works.
-
-
The Siplast Veral System is preferably applied by torching, which utilizes the closely controlled modified asphalt in the sheets themselves. The Irex is first applied to the substrate and is lapped a minimum of 3 inches both side and end. The Veral is then applied to the Irex with 3-inch side and end laps offset so as not to coincide with those of the Irex.

-
The finished assembly provides a strong, flexible, glass-reinforced membrane, completely shielded from the elements.
