Guardian Glass

About Us

Guardian Glass manufactures products for the commercial (Guardian SunGuard advanced architectural glass), residential (Guardian ClimaGuard), interiors (Guardian InGlass, Guardian ShowerGuard, DiamondGuard), automotive and technical glass industry segments. Its products include both float and value-added coated glass-products, such as tempered glass, low-emissivity (low-E) glass, mirrored and patterned glass, solar glass and insulating and reflective glass for a wide range of construction projects.

At DeWitt, we produce mirrors, tempered (or safety) glass and several types of coated glass products.
We also recently underwent a multi-million dollar expansion so that we could produce a line of products designed to keep the heat out in the summer and inside the house during the winter. As a result, air conditioning expenses are lowered while providing a more comfortable living environment.
