Details

The Catnic Arch Centre is a robust PVC-u arch form designed specifically for use over openings in external cavity walls, whether traditional masonry or timber frame. Its purpose is to provide a reliable and permanent centre for constructing segmental brick arches, ensuring accuracy and structural integrity on site. Please note the product is sold individually, so confirm the correct size before ordering.

Application

This arch centre is widely used by builders and contractors to simplify the formation of brick arches above doorways, windows, and other openings. It is suitable for cavity wall construction where a neat, long-lasting arch finish is required. The integral weep vent is a practical feature that helps discharge any moisture that penetrates the outer skin, protecting the cavity and inner wall from damp issues.
