Quality Double Glazing And Triple Glazing That Performs Exceptionally

Triple glazing uses three panes of glass within a window profile, whereas double glazing uses two. This additional layer of glass improves heat retention and soundproofing, helping reduce both heat loss and sound transmission from busy roads or external noise. While modern double glazing offers significant improvements in reducing cold air intrusion and heat retention, the extra pane in triple glazing provides an even lower U-value, meeting and often exceeding UK building regulations.

Double & Triple Glazing Options

We supply and install double and triple glazing from industry specialists Smart Glass and Planitherm. Each type of glazing provides added levels of security, energy efficiency, and soundproofing. Our double glazing reduces heat loss and cold air infiltration, while triple glazing offers an extra layer of glass for further insulation. Both options contribute to a comfortable living space with less heat escaping through windows.

These glazing options come in various styles, including upvc and aluminium frames, with a wide range of colours and spacer bar options to complement any home style. We also offer UV protection coatings, ideal for areas such as conservatories, as well as self-cleaning glass options for ease of maintenance.
