Masonry Openings

Overview

Preparing your masonry for casings, sill noses, and sub sills.

Masonry openings for a window or door increase when casings and/or sill noses are present.
Masonry widths are impacted by the specific casings that are present, whereas masonry heights are impacted by both the casings and the sill noses that are present.
The masonry opening is impacted considerably when some of our larger sill noses and sub sills are present.
