Double Glazed Units

Norwich Glass Company are the local, approachable and reputable company supplying and installing domestic and commercial double glazed units throughout Norfolk and Norwich.

Double Glazed Windows Installation

Also known as Insulated Glass Units (IGU), double glazed windows are generally installed to reduce the thermal conductivity between the inside and outside of a building. This in turn will reduce the amount of energy required to heat a building. Float, toughened, wired and laminated glass can all be incorporated into double glazed units.

As well as double glazed windows, many other types of glass have been developed to reduce heat absorption, self clean, or reflect heat back into a building, or away from it. Thermal conductivity can also be reduced by creating a wider gap between the two panes of glass, then filling this gap with Argon, Kryton, or Xenon, although the last option is rarely used. A range of thermally rated spacer bars are also now available.

Further reductions are possible with triple glazed units, but there are weight considerations, and these units can be heavy.

We supply and install double glazed units, as well as offering repairs to any unit with internal condensation issues.

Frequently Asked Questions

  • What are double glazed units?

    Double glazed units often consist of two or three panes of glass that are fitted separately into a window or door frame, the space in between them is then filled with gas or air to reduce thermal conductivity.

  • How long do double glazed units last?

    The lifespan of double-glazed units depends on the material of the unit and the installation method. All of our units are sealed with an epoxy resin, providing them with a 10-year guarantee.

  • How do I know if I need to repair or replace my double-glazed windows?

    There are clears signs that will help you to identify if there is an issue with your double-glazed windows or if it’s time for them to be replaced. These include internal condensation between the glass panes, and a draft or water working its way into the room via the windows. A member of our team will be able to advise on whether this requires a simple repair or a full replacement.

  • What is the benefit of double-glazed windows?

    If you have single pane windows and are deliberating on whether to upgrade to double glazed windows, the main benefit for this includes increased energy efficiencies.
