Everything You Need To Know About Double Glazing

High quality double glazing can reduce noise levels by approximately 35 dB, and triple glazing often achieves similar results. While good quality triple glazing can offer enhanced acoustic insulation, it really depends on the products, materials used and the installation. Windows manufactured with acoustic glazing often feature thicker glass, laminated layers and a wider gap between each pane.

Condensation manifests when moisture-laden air comes in contact with a cold surface – such as a windowpane. When you boil a kettle, cook food or have a hot shower, the air becomes filled with more moisture than usual and this is why kitchen windows and bathroom mirrors are most steamy. However, the key to reducing noise as much as possible is to disrupt the sound waves and frequencies as they pass through a material. This can be done by combining different thicknesses of glass close together. Sound is an energy that moves in waves, like waves on the sea, by vibrating the molecules of the air and objects it comes in contact with. When sound waves hit glass, the glass vibrates at the sound wave frequency and transmits the vibration to the air molecules on the other side of the glass.

I know it’s tempting, you have a unique piece and you think you can make it even better by using a new combination of glazes that work perfectly in your head. Whatever level you’re at with glazing, keeping detailed notes will really help you build a relationship with your glazes. It doesn’t guarantee that you won’t have issues with them, but will be invaluable when it comes to solving them. In either case, you want to zero a set of scales to the weight of the piece/test tile before adding the glaze, then weigh and record the weight after glazing. This works for dipping, pouring, or brushing a glaze (although if brushing a full piece, you might want to just record the start and end weight separately in case the scales time out before you finish).
Purpose designed to suit glazing systems in place of double or triple glazing. Super slim 41mm deep profile and fully tested by BSRIA to EN with rain rejection levels board up window to Class A. Many of our customers have original shutters in their listed or period homes. Because we custom design each CosyGlazing installation to work with original features, our integrated sash and casement window options can usually be fitted without the need to adjust original shutters. For casement windows, CosyGlazing sits perfectly either on the window restrictors frame, for a fixed solution. Or if you want your windows to open and close as they always have, we have developed modified traditional catches and stays to allow for the CosyGlazing unit to be fitted directly to the casement.

In most cases, secondary glazing is considered a "permitted development" and doesn’t require planning permission. However, exceptions may apply, especially in conservation areas or for listed buildings. We recommend checking with your local planning authority for specific guidance.
