We recently had new upstair windows fitted to our property. The fitters arrived at 8.30 in the morning and left, having cleared up all the mess at 5.30pm. The guys were very friendly and did an excellent job.

Double Glazing King's Lynn FAQs

Here are some of our frequently asked questions by our customers.

Everything from vertical sliding sash windows to aluminium windows, UPVC windows to casement windows, our windows can all be double glazed to ensure we can offer high quality products that are built to last for homeowners in King’s Lynn, West Norfolk.

Replacement windows and doors can come with double glazing, but it is important to consider factors such as the frame material and building regulations. This service is highly sought-after due to the numerous advantages that double glazing in windows and doors provides.

Yes, double glazing, as with secondary glazing conversely, when properly installed by our team of window fitters, can prevent outside pollutants and triggers from entering your home. In addition, the temperature control and anti-condensation measures of double glazing prevent moisture build up, providing a more comfortable living space. Having a dry home helps prevent the growth of mildew, mould, and other bacteria that can have negative effects on health.

Both styles of windows in King’s Lynn have the same purpose of reducing heat loss and noise pollution, but they vary in terms of style and installation method.

Double glazing consists of two panes of glass with a pocket of insulated air in between, and they are installed as a single unit. Secondary glazing, however, is installed by adding a second pane of glass or a plastic panel to the interior side of a single-glazed window, creating a gap filled with air between the original pane and the new one.

Double glazing is generally considered more effective than secondary glazing due to the use of insulating gases such as argon or krypton. These gases provide better protection against energy loss.

Additionally, double glazing is professionally constructed to meet industry standards, ensuring a tight seal.

However, secondary glazing does offer an advantage as it is less intrusive, making it more likely to be approved in listed buildings or other areas with similar protections. Secondary glazing is often a good option when intending to have double glazing repairs carried out.
