In this guide, we'll explain all you require to know about how to put glass on an aluminum storefront.
Glazing - What Is It?
If you've been doing research about glass, you might have heard the term "glazing" being used. The basic definition of glazing is the process of installing the glass. In this article, we will explain the process of glazing storefront doors or, in other words how to put glass on commercial doors.Understanding Glass Stops and How They Work
Glass stops are the aluminum extrusion that is used to hold the glass within the door. Glass stop extrusion is equipped with an insert that houses a strip of rubber, referred to by the name of glazing gasket, slides across the entire long length of glass stop extrusion. Glass stop extrusions are made to fit into the door via compression, which basically locks the glass in the door. The gasket for glazing compresses the glass to create a secure seal.Glass Stop Sizes
The most popular glass stop sizes are made using 1/16" glass. However other glass stop sizes are available which allow the door to accept insulated glass such as 5/8" or 1" glass with insulation.
Storefront Door Preparation
Before any glazing can take place the front door of the store needs to be prepared properly. Here are some important points to consider prior to installation of the glass.Glass Jack (Door Leveling Adjustment Screw)
The majority of storefront doors feature an adjustment screw in the top railing of the door closest to the stile of the lock. The adjustment screw is often known as a door leveling screw, or the glass jack. Before glass is installed, it is a good practice to ensure the glass jack has been backed off, so that the glass is in a position to be able to fit inside the door without interference.
Door & Frame Must Be Plumb and Square
Before the glass is installed the storefront door as well as frame should be level and properly anchored. It is recommended to put the door inside the frame and then verify the proper operation and swing of the door, as and any sag or height adjustment prior to installing the glass. Glass can be put in when the door is inside the frame of the door. However it is recommended to remove it from its frame before laying it flat on the floor of two sawhorses to ensure the glass is placed on top of it.Installing The Glass
Step 1: Install Interior Side Glass Stops
It is possible to have the glass fitted after the door has been placed in the frame of the door. However we suggest removing doors from frames and placing it flat on two sawhorses so that it will be easier to install. First, you need installing the glass's interior side stops. There are four glass stops for side windows (two for door stiles and two for rails of the door). The glass stops in the interior must have the gasket for glazing within them for the complete distance of the glass. The glass stop inside is engaged with the door and "slips" into place in the door.
Step 2: Glass Setting Blocks Placed
Flip the door around and then place it on the horses. The door must be turned upwards so that the gasket for glazing of the glass stopper inside is clearly visible. Before any glazing is done however, the door to the storefront should be prepared properly to be ready for glass installation. To allow the glass to be set against the front door, either rubber or plastic setting blocks should be placed over the doors. The glass will then sit on the block and prevent the glass to break. If the glass is set without the block for setting and the glass breaks, it could break because it is directly in contact with aluminum metal. For a standard 3'0" x 7'-0" (36" x 84") storefront door, there are four block sets for glass. There is a setting block on each side of top of the lower rail of the door, about 2 inches away from the stile of the door. It should have a set block the opposite edge of the stile that is about 2 inches away from the top rail of the door.
Step 3: Set The Glass In Place
Make sure that the glass is set in the setting blocks on the door's bottom rail. Be sure the glass is placed on the bottom rail, with an equally space on both sides of the door's stile. After the glass has been aligned, the whole piece of glass is ready to be inserted in the door. At this point, the glass must be placed on the door with an equal space on both sides and then the glass is placed against the internal glazing gasket. In most glass installations, there should be a minimum of 3/16" of a space between the glass as well as the stile or rail.Step 4: Adjust The Glass Jack
When the glass is set placed Adjust the screw for leveling of the door (glass jack) to ensure that it barely gets to the glass. IMPORTANT: DO NOT OVERTIGHTEN AS IT CAN SHATTER THE GLASS!
Step 5: Install The Exterior Glass Stops
Next step to put in the glass stops on the outside. As with the glass stops, they will need to have a glazing gasket throughout the width of the stop. Start by inserting one of the glass stops on the outside into the door. To install the glass stop, it needs to be pushed into the door and then "snapped" into place. In order to accomplish this we suggest using the mallet of a rubber and an nylon block or wood block to accomplish this. Begin at the edge of the glass stop, and put the wood block on the stop in front of you. With the mallet, hit the wood block until it snaps the stop into its place. Slowly, work your glass stop till the complete glass stop is snapped into position. Repeat the process for the remaining three glass stops on the exterior.
