Gaetane Patio Doors October 26th, 2017 - 04:01:54
Because slide-and-pivot doors have no hinges there is no requirement for a sturdy side frame; its only purpose is to cover the gasket that seals the double glazed unit. This means that the views afforded through the expanse of patio doors have minimal interruptions. At the time of writing there are two versions of frame-less glass doors available in the UK both using the slide-and-pivot technique: one manufacturer supplies their frameless glass doors with kite-marked double glazed units which have a visible seal the other uses an almost transparent method of sealing their double glazing. Contemporary by design the absence of visible characteristics makes frameless glass doors a viable option for period properties.
Traditional patio doors are made of wooden frames. Wood is certainly an elegant frame for a door. The main drawback those with wooden frames is cost. Arguably these doors are a lot cheaper than wooden ones. In terms of durability aluminum beats wood. With a high tensile strength aluminum is made to last a lifetime. It does not easily get scratched by cats or dogs like wood does; aluminum is virtually scratch-free if taken cared of properly. Longevity of aluminum cannot be questioned too. Compared to wood aluminum does not suffer from rot. Nor would it easily corrode. Pound for pound aluminum doors to your patio outmatch wooden ones where toughness is concerned.
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.
An alternative solution is to order patio doors with integral horizontal blinds factory sealed inside the double-glazing cavity. Proven to be reliable the blinds can be operated via a magnet system (there is an alternative electronic option) that enables the slats to be easily angled to control the amount of light filtering through and can also raise and lower the blinds for maximum light or shade. A major advantage of opting for internally sealed blinds rather than separate blinds is that they are totally maintenance-free - no arduous dusting or cleaning - and because the blinds are encapsulated inside the glazed panels they are exceptionally difficult to break.
