Misted Double Glazed Units
Double glazed units that are misted up happen when the glass inside begins to fog. This is usually due to the seals around the window unit perishing and allowing moisture to get in.

Another reason for a failed seal is inadequate installation. This can lead to problems like a lack of drainage gaps in the frame or insufficient spacing blocks for window units. This can also be caused when harsh cleaning chemicals are used or curtains are not properly fitted.
