Building Overview
- Building is 90,000 square feet with a 250ˈ nearly vertical roof surface.
- Deck is made of EPS and XPS boards, which are set in an aluminum grid in addition to a Kevlar® Cover, which is held down with negative pressure pumps run by electricity.
The Challenge
- Water penetrated the EPS and XPS surface when high winds from a hurricane hit the upper Florida Gulf Coast, removing the Kevlar® Cover that protected the building from water.
- Determining how to waterproof the building without installing a traditional new roofing system.
- Determining how to seal and prevent air passing through the joints of the EPS and XPS surface
Solution
- Highly reflective white surface reflects solar radiation and provides for better energy efficiency inside the building structure by decreasing building temperatures.
- Provides this particular building owner with a secondary line of defense against leaks and air passage through the EPS and XPS surface.
- The TOPCOAT® system provided the water resistance and security the United States Air Force relies on to protect their sensitive equipment. TOPCOAT® Liquid Fabric (requires no reinforcing fabric) provides a strong, flexible seal that will not become brittle and will expand and contract with the roof. TOPCOAT® Flashing Grade, once cured by the ultraviolet rays of the sun, forms a strong, flexible waterproofing seal.
