A visible "kitemark" on the glass is the consumers assurance that the double-glazed unit has been manufactured to British standards. The BSI has numerous standards, including: U-value verification, Window Energy Rating and Window Installation. The lower the U-value, the better the thermal performance and most local authorities will require this to be 1.8 or better to meet building regulations.
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.
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.
While sliding, folding or standard push-pull doors are part of style, they are given much important because they also have a lot to do with space. Sliding and folding patio doors are more preferred since they can give you more house space. Not only that, but a patio door that folds can also lead to a wide open patio that can make the sun shine in your home. Deciding on the type of opening for your door is based on your general preference; be informed though that there are many options to choose from.
