Ormazd Patio Doors October 26th, 2017 - 03:55:59
In the mid-20th century sliding doors became very popular - two or three panels of glass that slide along grooves in the floor. To distinguish them from traditional French doors they were marketed with the thoroughly modern name of Patio Doors and this is often the image people have today when that term is used. Easily installed in place of a window the immediate advantages were additional natural light and access to the garden. They also became a popular option to use where a pivot door opening space was limited or where the aperture was wider than a pair of French doors. Older installations were typically single-glazed prone to warping and usually became difficult to slide open and closed. Still available today but in a developed form with double glazing and rollers for easier sliding the popularity of sliding doors during this century has declined as bifolding doors gained market share.
Patio doors comprise an outer frame plus individual door frames. These can be made from wood (soft- and/or hard-wood) metal or alloys (usually aluminium) pvc (polyvinyl chloride a thermo-plastic polymer - the u stands for unplasticised) or a composite material which may comprise any of the foregoing materials plus grp (glass reinforced polymer). There is also a style known as frameless where the vertical sides of each door have no frames.
Some manufactures offer optional extras such as tinted glass anti-sun laminated obscured glass and Argon-filled double-glazing. It is also possible to match existing period features by specifying Georgian bar or leaded-light in rectangular or diamond style. An innovative option is switchable privacy glass which enables molecules inside the double-glazing to become transparent or opaque at the press of a button; this is expensive though typically doubling the original price of good quality patio doors.
It is now easier to choose the style for your door because homeowners now have more choices. In the old days most patios can do with any kind of door. Some even think that any door is good enough just as long as it closes and opens when you please it. Of course if you want your home to be in style then you also have to make sure that the patio door style you choose should not go against your homes general theme.
