SureSPan EX Prosoco R-Guard SureSpan EX® is a flexible, durable 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 R-Guard Joint & Seam Filler or R-Guard FastFlash®. SureSpan EX® absorbs thermal movement and wind-loading stresses. The system spans and seals across irregular window geometries. SureSpan EX® is fully compatible with most window sealants and glazing materials.
