RE: Can brake metal flashing be used with Tubelite Storefronts and Curtain walls?
To all concerned,
Brake metal flashing can be used on the exterior side of Tubelite storefront or curtain wall to prevent water from draining directly onto brick or masonry. Brake metal flashing should not continue under the storefront or curtain wall such that it bridges a thermal break or interferes with the perimeter seal. Be careful to avoid running brake metal flashing all the way under a window frame or it will cause condensation problems. It is also more prone to leaks at the seams and splices.
Tubelite’s storefront and curtain wall systems are tested without flashing. For our storefronts, we recommend using our extruded and thermally broken sub-sill. This allows the system to drain water effectively, while maintaining high thermal performance. Our curtain wall products drain at each horizontal and have no need for sill flashing underneath the frame.
