Our Frequently Asked Questions
Here are some of our frequently asked questions by our customers.
What is double glazing?
Double glazing is a window setup that consists of two panes of glass in a single frame, with a gap filled with a highly insulating gas. This helps to reduce heat transfer and noise, providing a peaceful living environment.
Double glazing can be installed in various types of windows and doors, including French doors and specialist windows.

Why choose KLIC for your double glazing needs in King's Lynn?
Double Glazing Windows have the potential to decrease energy costs.
By replacing your single-glazed or old double-glazed units with KLIC’s double-glazing, you can save money from the very outset. In fact, it his estimated that double-glazing can reduce your heating costs by up 20%, resulting in significant annual savings.High-Quality Energy Efficient Materials
Double-glazing units can experience significant energy loss, with up to 80% occurring at the glass edge. However, our windows in King’s Lynn are equipped with a warm edge spacer that has advanced composite construction. This ensures that our double-glazed windows perform well, even during cold weather snaps in winter. The reduction of heat loss at window edges results in a temperature increase of 3-4°C for our glass, leading to a significant decrease in condensation by up to 80%. Furthermore, the implementation of high-performance gaskets in our double glazing also helps in reducing noise pollution.Robust and Resistant
Our windows include Q-Lon weather seals, which are designed to provide high-quality performance in various temperatures. The construction of these seals helps absorb noise pollution, enhancing acoustic insulation. Additionally, they are resistant to rot, mould, mildew, UV rays, and ozone. These CFC-free seals are built to last for the lifetime of a windowWhat are the distinctions between double glazed windows and secondary glazing windows?
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.
Does double glazing have the ability to reduce allergens?
Yes, double glazing, 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. Having a dry home helps prevent the growth of mildew, mould, and other bacteria that can have negative effects on health.
