Quality Double Glazing And Triple Glazing That Performs Exceptionally

Triple glazing utilises three panes of glass within a window profile, whereas double glazing uses two. However, double glazing can also feature within door profiles. And whilst our modern double glazing options offer considerable benefits, triple glazing provides properties with an additional boost; the use of an extra pane further lowers U-values whilst enhancing levels of security and reducing the amount of external noise making its way inside.

Double & Triple Glazing Options

We supply and install double and triple glazing from industry specialists Smart Glass and Planitherm. Whichever option you choose, enviable levels of security, thermal efficiency and noise reduction are ensured. Homeowners can benefit from a home environment that feels truly comfortable, whilst installers can offer such incentives to their customers.

Specialist UV reduction options are available, which are ideal for use on conservatories. This is because they protect inhabitants from UV rays and severely reduce the discolouration of furniture caused by continual exposure to the sun. For ease of maintenance, we offer self-cleaning glass variations too.

      Full house installation with flush sash windows

      A huge thank you to Scott and Damien for doing an amazing job installing my windows. They were prompt, attention to detail and cleaned up after themselves. Nothing was too much trouble. I have no hesitation in highly recommending the team at GHW – thank you. 😃

      “We had an old set of wooden garage/workshop doors replaced with a set of aluminium framed bi-folding doors. Communication throughout was great and it was quick and easy to get a quote and then set a date for the work to be carried out. The installers were extremely friendly and professional, and we couldn’t be happier with the work they carried out.”
