A PVC-u arch unit for use over openings in external cavity walls
Can be used in both traditional and timber frame construction applications, it provides a permanent centring for brick arch construction enabling easy construction of segmental arches.
Extruded from PVC-u for greater UV stability, they've been designed to weather in accordance with the PVC-u windows. This design incorporates built-in weep vents for discharging the wind-driven rain that penetrates the external skin of a cavity wall.
