Arguably, French doors could be considered as retractable as each door can be pulled back. The advantage of retractable doors is that maximum access is possible between the two sides of the aperture whereas sliding panel doors generally overlap unless built to retract into a recess.
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.
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.
The patio wheel adjusting screws are located at either end of the bottom section of the door. Some patio doors have a blanking plug covering the adjustment hole, remove the plug and use a torch to shine into the bottom section of the door to determine where the screw is located and what type of screw it is. There maybe two screws that are visible, one is an adjustment screw and the other is a fixing screw that holds the patio frame together. Use a long screwdriver to turn the adjusting screw in a clockwise direction to raise the patio. Adjust both wheels the same and check if the patio is level by almost closing the door and noting the gap between the door and the frame. Adjust the wheels until the gap is even all the way down. You may need to move the door locking keeper on the frame after adjusting the wheels. If this didnt solve the problem you may need to replace the patio wheels.
Remember, when it comes to hardwood patio doors, you dont have to settle for the same old look everyone else has. In fact, its a good idea to do some online research and look at some photos of wooden doors, which can be a big help when youre trying to decide what you like best. To keep maintenance to a minimum, you can have the wood treated with a weatherproofing formula that protects the wood finish. This allows you to enjoy your patio and those stylish doors for many years to come.
