Can anyone help, I have had two pairs of patio doors fitted to my property, one set is 2350mm high x 2400 wide and a further set 2350 high x 1500 wide. I have reported to the suppliers that the doors are not meeting in the middle as they are bellying out. After several visit fitting heavier brushes between the closing edge, I am of the impression they are still letting in draughts.
yesterday I carried out a smoke test by lighting a smoke stick and placing in front of the area the problem is utmost, the reaction of the smoke confused me, you would have expected the smoke to rise but it done the opposite and went down toward the bottom of the door.
Can anyone tell me why this would be?
