How to Install Double Glazing in Windows

Looking for a way to improve the energy efficiency of your home, reduce noise pollution, and enhance the overall comfort of your living space? Then it’s time to welcome double glazed windows into your home sweet home. 

Opting for professional double glazing installation is typically the best way to go to achieve optimal results, but if you’re ready to put your DIY skills to the test, then we’ll walk you through the process step-by-step.

Step 1: Gather Your Materials and Tools

Before you begin, ensure you have all the necessary materials and tools. Here’s a checklist:

• Double glazed window units
• Measuring tape
• Spirit level
• Screwdriver
• Hammer
• Chisel
• Utility knife
• Putty knife
• Silicone sealant
• Expanding foam
• Glazing beads
• Protective gloves and safety glasses

Step 2: Measure Your Windows

Keep in mind that accurate measurements are absolutely crucial for a successful installation. Follow these steps:

1. Measure the height and width of the window opening from the inside.
2. Take measurements at three points: top, middle, and bottom for the width, and left, centre, and right for the height.
3. Use the smallest measurement to ensure the double glazed units fit properly.

Step 3: Remove the Existing Window

1. Remove the Stops: Use a utility knife to cut through any paint or caulk around the stops. Gently pry them off with a putty knife or chisel.
2. Take Out the Old Glass: Wear protective gloves and safety glasses. Carefully remove the old glass panes.

Step 4: Prepare the Window Frame

1. Clean the Frame: Remove any old putty, caulk, or debris from the window frame using a putty knife.
2. Inspect for Damage: Check the frame for any signs of rot or damage. Repair or replace any damaged areas before proceeding.
3. Apply Sealant: Apply a bead of silicone sealant around the inside edge of the window frame to create a watertight seal.

Step 5: Install the Double Glazed Unit

1. Position the Unit: Carefully place the double glazed unit into the window frame. Ensure it is centred and level.
2. Secure the Unit: Use glazing beads to secure the unit in place. Start with the top bead, followed by the sides, and finish with the bottom bead. Tap them gently with a hammer to ensure a snug fit.
3. Check for Gaps: Inspect the installation for any gaps. Use expanding foam to fill any gaps between the window frame and the double glazed unit.

Step 6: Seal the Window

1. Apply Silicone Sealant: Apply a continuous bead of silicone sealant around the outside edge of the window frame. This will provide an additional layer of protection against water and air infiltration.
2. Smooth the Sealant: Use a putty knife to smooth the sealant, ensuring it adheres well to both the frame and the double glazed unit.

Step 7: Reinstall the Stops

1. Reattach the Stops: Carefully reattach the stops you removed earlier. Use a utility knife to trim any excess sealant if necessary.

Step 8: Final Checks

1. Check for Functionality: Open and close the window to ensure it operates smoothly.
2. Inspect for Air Leaks: Hold a lit candle or incense stick near the edges of the window. If the flame flickers or the smoke moves, there may be an air leak. Apply additional sealant as needed.

Step 9: Clean Up

1. Remove Debris: Clean up any debris or leftover materials from the installation process.
2. Clean the Glass: Use a glass cleaner to clean both the inside and outside of the double glazed unit.

Step 10: Enjoy Your New Windows
