At glass repair company where I work in Philadelphia, Pennsylvania, at least once a week we receive a call A company or an owner with a double- Who asks us if we can replace it with a single glass panel.
Why, in the world, ask yourself, would anyone want to replace a double panel window by a single pane? There are two reasons for this. One is the time factor. Double – glazed windows (also called thermal or insulated windows) must be custom – designed and generally take between five and ten working days to manufacture, while the installation of a single shutter in the opening Is something that can be done that very same day. The other reason is the cost. As one might imagine, a double glazed window is more expensive. After all, a single glass panel is just that. Conversely, a thermal window, in addition to having obviously two panes, also has a bit of integrated technology. And technology is not cheap. Replacing a large double glazed window can be a significant expense.
Regarding the actual work, converting a double panel commercial window into a single pane is relatively simple. For modern glazings (known as "flush-glaze"), manufacturers sell a simple converter system that falls into the existing frame and reconfigured it to a single glazing width. The conversion of a residential window, however, is a different story. Residential frames and frames are designed to contain a double-pane window (known as a "unit") of very specific thickness, and due to the exclusive nature of residential windows and Doubt a general lack of demand, there is no system converter for this task. But that does not mean that it can not be done. Well, on that.
On a fairly regular basis, I meet an owner of a house or, more generally, an apartment dweller who for some reason, absolutely insists on the fact that, 39; they must have their double glazed window repaired that same day. It is for these customers that I have developed the following method for performing such repair, the result of which is semi-permanent (it can be easily reversed) and has a watertight seal .
After removing and disassembling the chassis, then de-icing the old thermal unit, a single piece of glass plate with a thickness of 3/16 or 1/4 inch (as opposed to the two 5/32 inch glass that is usually found in residential spa windows) is cut to a size that fits snugly into the chassis and is laid flat in a continuous silicone cord inside the side Outside the frame. Neoprene adjustment blocks of 1/16 inch thickness are then wedged along the edge of the glass, two per side. These act as a very effective shock absorber between the glass and the chassis and prevent the shutter from moving in any direction.
Then, a second bead of silicone is placed around the edge of the inside of the glass. Finally, a number of small sized wood blocks (typically two or three for each side) are wedged between the inner side of the chassis and the glass, forcing the panel to hang against the outside side of the chassis. The window is then reinstalled. After the silicone healing in 72 hours, the customer takes out the blocks of wood and it is done.
I have done this type of window repair for almost 15 years and I have never had a reminder or complaint. However, there are two reservations that must be explained to the client before agreeing to do the work. The first is obvious: they lose the thermal properties of having a double glazed window. The second is that, while the window will look like outside, there will be an interval of 1/2 to 3/4 inches inside the chassis. After all, if you put a 1/4 glass into an opening that measures 7/8 of an inch, you still have a difference of 5/8 inches. In the state, the interior of the chassis is the same color as the outside, so that the visual difference is negligible.
And there you have it.
