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.
Originally, patio doors were all of the French Door variety; that is, a pair of doors that are hinged at the sides and open from the middle, each door pivoting in- or out-wards. French doors are still popular, especially with builders of new homes, as they are comparatively cheap and easy to accommodate in place of windows and offer an alternative evacuation route for families, especially for elderly or disabled people, to meet improved fire safety requirements.
There are a wide range of designs, styles and options of patio doors to select from for your home. It is important to keep in mind the amount of space you are working with when choosing the right patio doors for your home. If you have a small space, you may want to go for sliding doors for your doors. On the other hand, a large patio would be best served by a pair of expansive French-style doors. The doors you select should also be weather tight against the elements such as wind, rain and snow.
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.
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.
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.
