Gaetane Patio Doors October 26th, 2017 - 04:09:17
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.
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.
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.
Remove the two screws holding the bottom section of the frame. There is one screw either side of the bottom section. Once these have been removed the bottom section can be prized away from the rest of the frame. Be careful not to lever against the glass or you could shatter it. When the bottom section is clear from the rest of the frame you will be able to remove the wheels. Some wheels have a screw holding them in and some are pressed into a holding bracket. If the retaining screws have rusted you can carefully drill them out taking care not to make the hole in the bottom section any bigger. Contact your local Hardware Store Glazing Shop or search on Google for replacement wheels.
