Installing your own secondary glazing in a few simple steps (DIY)

Installing your own secondary glazing can seem like a daunting task. Fortunately, we have developed several tools to help get you started. So in this step-by-step guide, we describe, step-by-step, two different installation methods for fixing secondary glazing. Of these two methods, we recommend the installation method with glazing clips. This is because secondary glazing with glazing clips is easy to open and easy to install. If the installation with glazing clips is not possible due to the structural situation, we recommend the fixed installation with screws. In this step-by-step guide, you will find a handy video where we show you how to tackle both methods.

Step-by-step guide for installation of secondary glazing with glazing clips Firstly, it is important to check whether the structural situation allows you to go for the installation method with glazing clips. Conditions for installation with glazing clips:

• Frame thickness at least 3.5 cm
• Frame that you can screw into
• No protruding hinges or handles
• Longest side of window maximum 2 metres

If this is not possible, see the step-by-step guide for fixed installation of secondary glazing.

Step-by-step guide for fixed installation of secondary glazing with screws Is your frame not suitable for installation with glazing clips? Then fixed installation may be an option. Conditions for fixed installation with screws:

• Frame thickness at least 3 cm
• Frame suitable for drilling and screwing
• No protruding handles or hinges
• Longest side of window maximum 3 metres

If even the fixed installation method is not possible due to the structural situation, check out alternative installation options here.

First of all, measure your frame using our measuring instructions. Have you opted for the installation method with glazing clips? Then first place a standard sheet of secondary glazing with your desired dimensions in the shopping basket. If you have opted for the installation method with screws, choose a sheet of secondary glazing with pre-drilled holes in your desired dimensions. Next, add the insulation tape and the required quantity of glazing clips or screws to your shopping basket. Check below how many glazing clips or screws you need per side.
