Storefront Glazing System

A very common system for glazing building lobbies, retail storefronts and interior glass walls, its metal (aluminum) cross section (head, sill and mullions) is 1-3/4" x 4" for 1/4" glass and most often is anodized dark bronze. The other 'standard' colors are: clear aluminum finish and white which are available at no additional charge.

Costs in this bulletin are presented in a "Rule of Thumb" context. Various factors will affect actual project cost. Among these are: project difficulty, size, market forces at the time of bid.

Using the table above, one can easily calculate the approximate cost of filling an opening with a glass store front and door. Say you wanted to remove a 12' x 12' roll up door and fill the opening - Multiply the area of the opening (144 SF) x $25.00/SF for the 1/4" glass and framing ($3,600.00) and add one door, 3' x 7' ($1,200.00) = $4,800.00

On occasion, doors and glass will have to be a color other than 'standard'. Add $5.00 per square foot (of storefront area) for custom paint . In the example given above, a custom color would add $720.00 to the job.

1/2" Butt Glazed Wall System

A "butt glazed system" ("butt", in this case, referring to the vertical edges of the glass) relies on the thickness (1/2") and tempering of the glass to support itself without a metal frame. It makes a very elegant glass wall found in higher-end tenant improvements.
