About this detail

An ETFE two-layer cushion is secured at the perimeter by an aluminum extrusion cap with a clear anodized finish, fastened with a stainless steel cap screw and washer. Continuous grey silicone gasket seals are placed above and below the ETFE layers, and an EPDM gasket isolator is positioned beneath the extrusion. The aluminum base extrusion is bolted to a four-inch steel upstand with stainless steel bolts, nuts, and washers, using four fasteners at each upstand. The painted steel upstand bears directly onto a painted pipe arch.
