Lamp in a room with windows in it


Did you know that glazing your windows makes your home more energy efficient? Window glaze helps to keep the warmth in during winter and the heat out during summer, as well as protecting your home from excess condensation.

If you want to learn how to glaze your windows the easy way at home, check out our step-by-step guide.

Safety tip: Always wear the appropriate safety equipment (safety glasses, ear muffs, gloves and mask, for example) and always follow the instructions for the product or equipment.


1Clean the area

Start by using a microfiber cloth and glass cleaning spray to remove any dust and debris from your windows. Give the edges a good wipe down, too. This will ensure that the glaze has a clean, smooth surface to stick onto. Wait a few minutes for your windows to fully dry before moving on to the next step.

2Use doubled-sided tape

Using double-sided tape, carefully line all four edges of your window frame and repeat for each window that you are glazing. Cut the tape to size using scissors.

3Measure your window

Using a measuring tape, measure out the length and width of the window frame. This figure will tell us the exact size we'll need to cut the adhesive film to. Record and repeat this step for each window that you're going to glaze.

4Cut to size

Unroll your adhesive film onto a clean, flat surface. Using a ruler and pen, mark out the length and width you measured earlier. With a pair of scissors, cut down the length-side first, followed by the width until you have your desired adhesive film size. Repeat this step for the number of windows you are glazing until you have enough pieces to cover each window.

5Remove the paper

Before sticking the film onto the window, you’ll need to remove the backing paper on the double-sided tape to reveal the sticky side.

6Stick the film

This is the trickiest part of the whole process! Take your adhesive film and start at the top two corners of your window. Carefully stick each corner of the adhesive film onto the top two corners of the double-sided tape. Then, stick the bottom two corners down. Carefully run your hand down the edges of each side, smoothing out the film where needed. The straighter you get the adhesive, the neater your finish will be.

Don’t worry if there are tiny air bubbles or wrinkles; we’ll fix this in the next step.

7Dry the area

To remove the wrinkles from the film, we’re going to use a heat gun or a hair dryer.

Switch on your heat gun (or hair dryer) and hold it approximately 30cm away from the window, working to smooth the wrinkles out of the adhesive film. Remember not to get too close to the film with your heat gun, as this can damage the finish. Repeat this step until all windows are complete.

Head to your local store to find everything you need for D.I.Y. window glazing.

Health & Safety

Please make sure you use all equipment appropriately and safely when following the advice in these D.I.Y. videos. You need to be familiar with how to use equipment safely and follow the instructions that came with the equipment. If you are unsure, you may feel it is safest to consult an expert, such as the manufacturer or an expert Bunnings Team Member.

Grave health hazards are linked to asbestos, which may be in homes built up to 1990. Health hazards may result from exposure to lead-based paints in older materials and copper chromium arsenic (CCA) treated timber. For information on the dangers of asbestos, lead-based paint and CCA treated timber and tips for dealing with these materials contact your local council's Environmental Health Officer. You can also use a simple test kit from Bunnings to indicate the presence of lead-based paint.
