I have bedroom with huge sliding door that is double glazed. however the bedroom is always cold. I noticed that the sliding door tracks where the door slides pumps cools air from outside making the room extremely cold, is there a way insulate these gaps?
Hello @jp171
If there is enough space between the sliding door and one of the rails, I suggest looking at installing a Moroday 6 x 7mm x 5m Black MWS8 Self-Adhesive Brush Seal. But if there is no space for it, I recommend putting two 88cm x 5.3cm x 5.3cm Assorted Colour Door Snake to stop any cold air from flowing under the door. The snakes can be removed when using the door and repositioned when its closed.
If you need further assistance, please let us know.
