draught around warped composite door

TheCyclingProgrammer

You should try increasing the compression, move the top and bottom keeps towards the outside a notch and the central latch keep inwards a bit to compensate. You want the hooks to engage without fouling and from the outside there should be gaps between the door and gasket.

If you can do this then you should have no drafts. I have no idea if it will pull the door back into shape. Maybe, over time.

I'll look to see if the bottom & top latches move,
at the moment all the latches work ok,


as the door bows out of the frame at the top & bottom, I will have to move top & bottom latches the opposite way into the frame

Why do you say it is not under warranty? Manufacturers give product warranties, for example Duraflex, DoorStop and so on. Only on Friday was I dealing with the latter on a dodgy door installed five years ago, and there is still another five years guarantee to run on that one.

In mitigation to all folks the manufacturers do not broadcast their warranties - it is all hidden from the consumer for deliberate commercial reasons. But do look carefully into this.

That's right - towards the outside of the house.

You could also remove the centre screws holding the reciever side of the frame and put a packer between frame and plaster around the middle to force frame in line with door
