Double Glazing

Arrange A Free Quotation

Double glazing or sealed units is the glazing process in which a window is formed by two panes of glass with a space between the panes. The space between the glass is usually several millimeters thick. Air is trapped between the panes of glass and forms a layer of insulation. Before the unit is sealed, a drying agent is added to ensure that no moisture is present inside the finished glass unit. The double glazing unit must be airtight.

If condensation appears between the panes, it indicates that the sealed unit is not airtight. Sealed units cannot be repaired; if condensation appears, the unit must be replaced.

Customer Reviews

Incredibly professional. Excellent; communication, work, tidiness, price, time. I added on work whilst here and it was no problem to do for me. Can't really recommend enough. Now inspired to get more windows done with more attractive glass.

Very quick response to the initial enquiry, and all the way through. Turned up when they said and did a good job.

We had an old set of Upvc French doors with a cat flap installed in the glass. They were very draughty and it made the kitchen cold. Commglass replaced the glass, adjusted the handle and generally serviced the unit. It is now tight and draught free. They did an excellent job, prompt, tidy and great communication. Have used before and will use again.

Brilliant professional job beautifully done perfectly. What once looked horrendous and had all blown and could not see out of is now a fresh shiny velux window where i can see all my views right across to South Downs. A big thank you to Commsglass I will definitely use you again and I highly recommend. I wished i could show a picture of before and after!!! As it looks so bright in my kitchen
