Have you got misted double glazing in your home or office? This happens when the seal on double glazed glass fails or breaks down. Broken seals mean that the insulation effects of the glass units are compromised so it’s important to get these replaced.

A damaged double glazed sealed unit doesn’t mean you need to replace your whole window. Replacement double glazed units are much cheaper so as long as the frame is in good condition, there is no need to go to the expense of a completely new window. You can even upgrade your glass to A-rated energy efficient to help improve insulation and lower your heating bills.

CN Glass supply and install double glazed units to strict British standard and our glazed units come with a 10 year sealed unit guarantee.
