Historic Church Stained Glass Protection

Project Overview

This project demonstrates how Hammerglass glazing can be used to protect large leaded stained glass windows in a historic church. The existing windows measured approximately six metres in height and required an additional protective barrier that would preserve both their appearance and structural integrity.

ProtectAll supplies and fabricates Hammerglass glazing solutions for heritage buildings, religious facilities, public institutions, and other architectural projects across North America where security must be achieved without compromising design.

The Challenge

Historic churches often feature original leaded stained glass that is both architecturally significant and highly vulnerable to vandalism, accidental impact, and weather exposure. Replacing damaged stained glass is expensive, time-consuming, and may require specialized restoration.

Any protective glazing system must preserve the building’s original appearance while providing reliable long-term protection.

The Solution

Hammerglass Single panels were installed as an external protective glazing system to shield the existing stained glass without altering its visual character. The large glazing panels were joined using a tongue-and-groove system and secured with transparent Hammerglass mounting profiles, maintaining a clean and discreet appearance.

Thanks to its lightweight construction—approximately half the weight of conventional glass—Hammerglass can often be integrated into existing window structures without significant modifications, making it well suited for heritage preservation projects.

ProtectAll provides custom fabrication and supply of Hammerglass glazing systems for similar restoration, preservation, and security applications throughout North America.
