Whether you want to reduce noise pollution in your home, increase comfort, or just improve the overall appearance of your space, installing double windows is the answer.
But their installation is easier said than done, as it involves many complex steps. In today’s article, we’re outlining all of them so you know what the contractor is actually working on.
Measure Your Windows
Accurate measurements are the foundations upon which the successful double glazing window installation will stand. It means you need to measure the height and width of the opening from both the inside and the outside. Also, take measurements from the top, middle, and bottom for width, and from left, center, and right for height. It will ensure no detail is missed.
It’s also important to use the smallest measurements, like inches, so every unit fits perfectly.
Remove the Old Frame
When your measurements are ready, you can start removing the older frame by carefully unscrewing it. You may even need to cut some parts of the frame to remove it fully. Once you’ve unscrewed, use a crowbar to pry the frame from the wall. You need to apply steady and consistent pressure to loosen it. If you think it’s stuck, you can use a hammer to dislodge it.
Now that the old frame is out, you can clean the window openings by scraping off any sealant or debris. This will make the surface perfectly ready for the new frame.
Prepare the New uPVC Frame
Now, it’s time to pick a frame that is almost 10mm smaller than the wall opening. This way, the new frame’s materials will contract and expand properly. Similarly, the right size will also deliver a weatherproof fit. It’s similar to a fountain installation where you also first install a right size of frame.
Now, you can use silicone caulk to fit the endcaps to the ends of the sill (so the moisture never enters the frame). Position this sill into the frame and apply a bead of silicone to seal it in place.
Install the Double Glazed Unit
You can now place the unit into the window frame. Make sure it’s centered and level. The glazing beads can also be used to fit the unit. You can start with the top bead, then move to the sides, finishing with the bottom bead.
Also, check the installation for gaps. The expanding foam can be used to fill gaps between the frame and the double-glazing unit.
Reinstall the Stops and Check for Final Functionality
You can now reattach the stop that you removed earlier. If you notice any excess sealant, use a utility knife to trim it. The final check will involve opening and closing the window to see whether it operates smoothly.
To check for air leaks, you can hold a lit candle near the edges of the windows. There may be a leak if the smoke moves. In that case, you can apply additional sealant.
Bottom Lines
Your window is now fully installed. You can clean up leftover material or debris to add the final touches. Regular cleaning of glass is also important to maintain a neat finish.
