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.
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.
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.
As with any kind of door for the home, your door can also be made of different materials. A door on the patio can be made of wood which is the most popular one. Wooden doors are popular because wood can easily blend in with both the interior and exterior of a house. French patio doors, for instance, has always been made of wood. Nowadays, though, you can also consider other materials such as fiberglass or even PVC doors for your homes patio. When choosing the kind of material, of course, you should consider the kind of protection that you will need. Be sure that your patio doors are protected from harsh sunlight, strong winds and rain. Also, you can consider having your patio screened so that the insides of your home can also be protected from insects and bugs.
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.
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.
