7 Frequently Asked Questions about Industrial, Commercial, Church and School, Factory and Security Windows

Question 7 - How are commercial glass block windows installed? How can you help us with this project? - We provide design, fabrication and installation services on a regional basis. Nationally we design and prefabricated stackable window sections and work with building owners and contractors on how to successfully install. Here are 3 basic steps in this process:

Step 1 - Measure the openings and call us to determine the size of the prefabricated window panels.

Step 2 - Install structural aluminum channels (for larger openings) at the top (head) and jambs (sides).
