Pecora XL-Span Silicone Transition Membrane

Pecora XL-Span Pre-Formed Silicone Transition Membrane utilizes a translucent high-molecular weight, 100% silicone composition. XLSpan PreFormed Silicone Transition Membrane is extruded to create a flat, ribbed profile which is designed to create an airtight transition seal between curtainwalls and the building envelope. These flat profiles are provided in a ribbed configuration in order to control adhesive thickness and maintain a consistent sealant configuration. XL-Span Pre-Formed Silicone Transition Membrane may also be used as a flashing material as well as a transition membrane between belowgrade and roofing materials to the building envelope.
