Here's How it Works!
In a Bi-Glass® conversion, your original window sash is removed from the frame by a trained technician. The sash is taken outside your home to a mobile workshop. Here the technician uses a patented tool to route out the old window putty and glass. This makes room for the new, insulated glass which is installed using glazing tape, caulking and exterior wood stops. The interior muntins (grillwork) always remain intact and virtually unchanged. On the exterior of the glass we apply a muntin that matches the interior grid thereby retaining the authentic look of your original single-glazed window. In addition, we replace your sash cords, or install new jambliners or hidden balances, weather-stripping, insulation, and locks to eliminate all drafts. The sashes are then reinstalled into their openings and adjusted to fit snugly.
You Can Have Your Cake and Eat it Too!
The Bi-Glass System ® gives you state-of-the-art energy efficiency, while retaining the character of your windows. With the Bi-Glass System your windows are efficient, double-glazed units comparable to commercially manufactured wood windows.
Customizing and Condition are No Problem!
Because we use existing wooden sash, odd-sized windows present no problem; we simply custom size the new glass. We offer a variety of different balance systems if for some reason you do not want to keep your original sash weights. From hidden balances cut into the sash, to vinyl compressible sash balances that reduce infiltration and allow the window to be opened easily and tilted inward for cleaning, we have a solution for you. Don't worry about the condition of your windows. If windows show an excessive amount of rot, we will repair with epoxy consolidation, replace parts of the sash or the whole sash with matching units. Bi-Glass works on virtually any style of wooden window including awnings, casements, picture windows, round-tops, extra-large units, and doors.
