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.
Some manufactures offer optional extras, such as tinted glass, anti-sun, laminated, obscured glass and Argon-filled double-glazing. It is also possible to match existing period features by specifying Georgian bar or leaded-light in rectangular or diamond style. An innovative option is switchable privacy glass which enables molecules inside the double-glazing to become transparent or opaque at the press of a button; this is expensive, though, typically doubling the original price of good quality patio doors.
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.
