SureSpan EX is designed to help create flexible and durable transitions between various types of air and water barriers and the curtainwall, storefront, or window being installed. Able to span large or complex transitions with a durable, flexible, elastomeric seal, SureSpan EX is easy to install and requires no mechanical fasteners.
R-Guard SureSpan EX is an extruded, elastomeric, pre-cured silicone material designed to help create flexible and durable transitions between various types of air and water barriers and the curtainwall, storefront, or window being installed. SureSpan EX provides a continuous bridge between the window and/or curtainwall openings and the adjacent air and vapor barrier materials. SureSpan EX is designed for high-movement, dynamic joints which are too large to be spanned by Joint & Seam Filler or FastFlash®. SureSpan EX absorbs thermal movement and windloading stresses. The system spans and seals across irregular window geometries. SureSpan EX is fully compatible with most window sealants and glazing materials. R-Guard SureSpan EX bonds to substrates with R-Guard SureSpan Adhesive. SureSpan EX is supplied in a translucent, “caution” yellow to simplify inspection and quality control.
