Preparing your windows for secondary glazing

Secondary glazing can help you boost the heat retention, security and sound reduction of your primary windows. With secondary glazing, a secondary window is added to your existing window on the inside. The additional window is a separate unit within its own frame. Secondary glazed units can be adapted to suit any style of primary window from horizontal, vertical or even York sliders, norman and gothic arches and even curved in plan to give just a few examples. Secondary glazing is most commonly utilised by homeowners who are searching for a solution to provide thermal and acoustic benefits to original windows without detracting from their period features.

Prepare for the winter

Preparing your windows for secondary glazing

The early Autumn is a popular time to install secondary glazing, with many people having installations in September/October just before temperatures drop substantially. However, with lead times increasing towards September it is beneficial to place your order soon to ensure you’re ready for when the colder weather bites. 

There are many steps you can take to prepare your existing windows for secondary glazing. Before installation takes place, primary windows must be checked for issues such as rot. They will need to be in good condition and if any painting is required it is advisable to carry this out prior to the secondary glazing installation. It is very important to have work done on your primary windows if they require it before the secondary windows are added to ensure that the secondary glazing is able to achieve the thermal and acoustic benefits for which it has been designed.
