Protective Glass Framework

A good solution for insulation and protection for your windows and wood framing with stained glass is to install an outside protective glass covering.

Protective glass covering can easily be attached to existing framing or new framing to eliminate: heat loss, cooling loss, water damage to paint and wood, effectively preserving your valuable stained glass windows.

It is important to allow proper ventilation both inside and outside to prevent damage to your stained glass.

New Framing System

TERHAAR stained glass studio provides and installs the finest anodized or painted thermally broken aluminum framing available.

Ventilation is important to include in your installation.

The framing can be a custom vent to fit any architectural style or a stained glass window design.

These frames house both the stained glass and insulated glass in one energy-efficient and cost-effective unit.


Installations range from high on a steeple to small windows at ground level.

TERHAAR has the experienced craftsman to install your stained glass windows properly.

Our experts are committed to helping you access the condition of your stained glass. Let us help you preserve your masterpieces for generations to come.


As we entered the church, we were in awe over the design

of the stained-glass panels surrounding the cross.
