When a homeowner decides to replace their windows with double glazed units, contracts are signed, measurements taken, and in a few weeks, your new made to measure windows arrive, ready for installation. Many people wonder about the actual fabrication process, and with that in mind, here is a brief rundown of how double glazed windows are made.
The Frames
These would be made from one of the following:
- UPVC
- Aluminium
- Solid Timber
The UPVC frames have an inner core made from galvanised steel, and the UPVC coating is think enough to provide protection. Aluminium frames should incorporate a thermal barrier, which prevents condensation building up on the frames, and the units are made to very precise dimensions. There is a reliable windows supplier in Tamworth who can quote for any project.
The Double Glazed Units
Using a 20mm space bar, the two sheets of glass are hermetically sealed, which prevents condensation, and toughened safety glass is used as standard in the double glazing industry. The sealed units offer a high level of insulation when compared to a single pane of glass, and this also improves sound insulation.
The Fixings
The sealed units are slotted into place on the frame, then neoprene gaskets are put into place, which effectively seals the glazed unit to the frame, and once this is done, the window is ready for installation.
The window frames are installed first, with the double glazed units added after the frame has been fixed in place, and a good installation team could finish a two storey house in a couple of days. Plaster is rendered on the inner reveals and a mahogany window board would be fitted to the interior, then the area can be painted or wallpapered.
