The latest patio doors innovation is slide-and-pivot doors. Developed and launched since 2007/8, slide-and-pivot doors incorporate the major benefits of bifolding doors and sliding patio doors. Comprising a number of individual glazed panels that fit snugly together when closed, there is a master door that can be opened with a standard (pivot) action, enabling the other doors to be moved, individually, along the top and bottom guides; as each door is moved to the end of the guides, it can also pivot open to increase the access width between the divided areas ( to a suggested maximum of approximately 8 metres).
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.
As with timber, the quality of pvc frames available can vary - and generally, you get what you pay for. The better ones will usually be reinforced with metal, internally, for greater strength but the cheaper options can be a nightmare to live with - sticking, twisting, splitting, discolouring, warping - often within a very short time. Most usually supplied as white, some manufacturers offer limited colour options or wood effect finishes.
Patios are designed to be a continuation of the house into the backyard area, and with this in mind, the doors often have quite a bit of glass in them to offer you a good view. While you may enjoy this view, the thing is, there are times when youd like to have some privacy separating you from others outside and vice versa. Controlling the amount of sunlight that enters the home through the patio doors is another issue of concern. Bright light shining into a room isnt always desirable, so you need a solution that solves both problems at the same time.
Metal frames, usually aluminium, provide strength in compact form. As notoriously good conductors (which is a bad attribute for insulation), frames made from aluminium are thermally-broken, which is a good attribute. It means that the metals on the inside and outside of the door frames are not joined, preventing the temperatures from being transferred between them. A bare metal frame would look completely unattractive so it is powder-coated in a choice of over 100 standard colours, including a white that resembles pvc.
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.
