Generally, timber frames are considered more traditional and can look beautiful! Hard wood such as oak is, as the name suggests, far more hard-wearing than a soft wood such as pine. Weather, especially strong sun, can take its toll on timber frames which could need to be varnished or painted annually. Wooden frames can swell and shrink with humidity, therefore opening and closing doors can require force and gaps can allow draughts in colder temperatures.
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.
You may not have notice, but your old fashioned patio door is causing you to spend unnecessary energy. Ordinary glass is a notoriously good thermal conductor. During summer months, it can let heat from the outside to travel inside. And when it is winter, it can easily radiate coldness inside and may cause drafts. More heat or cold inside the home during summer or winter translates into more use of air-conditioning or heating systems. That means more energy use and more carbon emission and more expensive electric bills. But these doors are such an elegant household feature that many home owners before are not worried about spending more money for electricity and more energy that would cause more carbon emissions. Some have advocated the use of tinted patio glass doors. While tinted glass may be a good thermal insulator, it would deprive a home owner the most valued asset of this type of door: visual transparency. A patio door that would not allow a home owner to relax inside his home to get an uninterrupted view of his garden or yard would be just the same as a standard entry door.
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.
