A typical installation of insulated glass windows with uPVC frames. Possibly the earliest use of double glazing was in Siberia, where it was observed by Henry Seebohm in 1877 as an established necessity in the Yeniseysk area where the bitterly cold winter temperatures regularly fall below -50 °C, indicating how the concept may have started: [2]
Weatherstripping can be used on windows to seal them on all sides. Metal caps on the window top [5] and on sashes [2] redirect rain to drip off instead of infiltrating. Foam or gasket weatherstripping can be applied to the sides and sashes. [6]
These problems can be solved by careful repair and the introduction of draught stripping. It is also a common problem for painters to paint the sash stuck. The sliding mechanism makes sash windows more vulnerable to these problems than traditional casement windows. Sash windows are relatively high maintenance, but offer advantages in return ...
Uranium glass used as lead-in seals in a vacuum capacitor. Glass-to-metal seals are a type of mechanical seal which joins glass and metal surfaces. They are very important elements in the construction of vacuum tubes, electric discharge tubes, incandescent light bulbs, glass-encapsulated semiconductor diodes, reed switches, glass windows in metal cases, and metal or ceramic packages of ...
A seal is a device or material that helps join systems, mechanisms or other materials together by preventing leakage (e.g. in a pumping system), containing pressure, or excluding contamination. The effectiveness of a seal is dependent on adhesion in the case of sealants and compression in the case of gaskets .
A door draught excluder is placed at the bottom of a door to cover the gap located at the threshold. [1] [2] In the Victorian era these draught excluders would be sausage-shaped and made from fabric stuffed with sawdust. [3] Tubular sand-filled fabric draught excluders are commonly referred to as "door snakes" in Australia.
The material comes in a range of colors and finishes, including a photo-effect wood finish, and is used as a substitute for painted wood, mostly for window frames and sills when installing insulated glazing in new buildings; or to replace older single-glazed windows, as it does not decompose and is weather-resistant.
