Sight lines is the term used to describe the interruptions in the view through the doors; in other words, the width of the vertical opaque areas between the glass when the doors are closed. On hinged doors, such as French doors and bi folding doors, timber and pvc frames generally have broad sight lines because, unlike aluminium, narrower frames would not be strong enough to be fit for purpose. As a guide to the width of two frames together, cheaper pvc door frames can exceed 200mm, aluminium frames are typically between 135mm and 160mm and frameless patio doors sight lines are under 40mm. Depending on the width of each door and number of doors to be installed, the difference in glass to frame ratio could be significant.
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.
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.
Going with a wooden door style means that youll probably pay a bit more, and youll need to keep up with their maintenance if you wish to keep them from getting that weathered look. However, wood is a luxurious material that provides your home with a natural ambience and charm. Patio doors can be found in hardwood types such as oak, cherry and mahogany, which are strong and blend well with many interiors and exterior areas.
An alternative solution is to order patio doors with integral horizontal blinds, factory sealed inside the double-glazing cavity. Proven to be reliable, the blinds can be operated via a magnet system (there is an alternative electronic option) that enables the slats to be easily angled to control the amount of light filtering through and can also raise and lower the blinds for maximum light or shade. A major advantage of opting for internally sealed blinds rather than separate blinds is that they are totally maintenance-free - no arduous dusting or cleaning - and because the blinds are encapsulated inside the glazed panels, they are exceptionally difficult to break.
A good place to start would be a home design store that offers patio doors with built in blinds. You will need to know the measurements of your door area in order to get an idea of the sizing needed. The more popular door units will be energy efficient to keep your home insulated from both hot and cold weather temperatures. The actual blinds themselves are usually white in color and have features like tilt and raise operation and maintenance free styling. These doors are also built to be strong and weather resistant, so they should last for years without any problems.
