How to fix the problem
Daft coming in at lock side: To sort this out just open the door and turn the round cams with an Hex key. Turn it one way to loosen door against seals and turn it the other way to tighten door against seals. In some case if there is no round cams on the door lock. Than look at the door keeps on the frame. You will find the adjustments there.
Draft coming in at the hinge side: Most pvc door hinges have an adjustment on the top of the hinge. Note there may be a plastic cap covering it. If so take of the cap and just like the cams on the door lock, you will need a hex key to turn them. Once you have located them just turn them one way to tighten against seals and the other way to loosen against the seals. TIP: if you lift the door about one or two millimeters with a crow bar. This will take the weight of the hinge and allow you to turn the hex nut in the hinge more easily.
Draft coming in at top of door: If this is the case, it could mean your door is after sagging a small bit. If this is the case you can lift the door back up by adjusting the hinges. On the bottom of the hinge you will find a hex nut. Turn this and your door will move upwards. Adjust all three hinges the same so that the weight of the door is spread across the three hinges. TIP: if you lift the door about one or two millimeters with a crow bar. This will take the weight of the hinge and allow you to turn the hex nut in the hinge more easily. Note: if your door is after sagging to much, you may not be able to adjust it enough with the hinges, and door may need to be Toe & healed. If this is the case you might need to call in someone who knows what they are doing as it involves taken out the glass or panel.
