In addition to beautiful designs and privacy features, decorative door glass has the ability to withstand severe weather and help conserve energy through better insulation. Whether you are replacing old glass or adding to an existing door, ODL Doorglass will provide a long life of performance, safety and durability.

When door glass is outdated or low-quality, it can present a variety of unexpected challenges. Old, fragile glass may not be able to maintain the desired indoor temperature of a home, nor meet wind-borne requirements in High Velocity Hurricane Zones. Low-grade door glass frames are also susceptible to problems, including squeeze out, corner flare and heat warping in west-facing doors. You can address all of these concerns through incorporating well-constructed glass and frames that meet green building and missile impact requirements. Here is how to properly qualify and install replacement door glass.

First, qualify the existing door and make sure its material can support the replacement glass. For example, the insulated glass units may not be designed for use in all wooden doors or doors without steel frames. Fiberglass or thick residential steel will give you the best results. If the existing door meets these conditions, measure its thickness, as well as the width and height of the existing glass. The door should be at least 1¾” thick and fit the existing glass opening within (+/-) 0.5”. The precise dimensions may vary by manufacturer.

If you are replacing full-size door glass, remove the door from its hinges and change the glass lying down; otherwise, the door can stay upright. Make sure there are two installers on hand during the entire project. A 22”x64” insulated glass unit can weigh up to 80 pounds and you do not want to take any chances carrying it alone. The extra assistance will help you move through the project efficiently and error-free.
