A glass manufacturer whose products include coated and low-E glass used by window makers and building projects.
Guardian Glass is a glass manufacturer serving the building industry. Its website describes coated and low-E glass, along with products for commercial and residential projects. Most homeowners never buy glass directly from a maker like this. Instead, the glass is built into insulated glass units by the window manufacturer, and the name appears on the spec sheet or the spacer label.
We are an independent contractor, and our job is to explain what glass packages mean for your home. We compare clear, low-E, laminated and tinted options, talk about sun exposure room by room and help you choose a package that fits your windows. When glass has to be replaced in an existing window, we measure the unit and match the type as closely as we can.
