Details

The Catnic Arch Centre is a specialist PVC-u arch unit designed for use over openings in external cavity walls, suitable for both traditional masonry and timber frame construction. It provides reliable, permanent centring to support the formation of segmental brick arches, making it an essential component for builders and contractors working on structural openings. Please note, each unit is supplied individually and includes integral weep vents to manage moisture effectively.

Application

This arch centre is typically used to facilitate the construction of segmental arches above doorways, windows, and other openings in external cavity walls. Its robust design ensures consistent arch shape and support during brick laying, helping maintain structural integrity. The integral weep vents allow rainwater that penetrates the outer leaf to drain away, reducing damp issues and prolonging the life of the wall. Suitable for use with Catnic lintels, it’s a trusted choice for site managers and tradespeople aiming for precision and durability on serious projects.
