During renovation work, the choice of windows is one of the biggest concerns for homeowners. They should be sturdy and durable, but also look good. Like many others, you’ve decided to replace your old aluminum windows. Here’s an article that explains how to go about it.
What are the advantages of aluminum windows?
The reason aluminum windows are so popular right now is that this type of window offers a huge number of advantages. Most importantly, these windows and doors blend seamlessly with the architecture of modern homes. But of course, that’s not all. Aluminum windows offer excellent security and durability, especially since aluminum is a strong, rust-resistant material. As you may have already guessed, these windows are also attractive because they lend a touch of elegance to homes. Thanks to their slim frames, they blend seamlessly with the walls, creating a beautiful look. Anyone who wants an aesthetically pleasing home should opt for an aluminum facade. Another point is that aluminum windows are available on the market in many different colors and styles. They require little maintenance and guarantee excellent thermal insulation.
What are the most important steps when installing an aluminum window in an old building?
If you'd like, you can install your aluminum windows without hiring a professional. Installing an aluminum window involves several steps:
- Cleaning the Old Window Frame: To ensure the new window is installed properly, the old window frame must be in good condition and securely attached to the masonry. Therefore, first remove the old hardware, then brush and clean the area. We recommend treating the area with insecticides and fungicides;
- Preparing the Level Substrate: After cleaning the frame, you must prepare the level substrate. To do this, seal the drain holes with silicone caulk. Measure the grooves and cut the strips to size; after applying glue to the underside of the installation areas, nail the strips in place;
- Preparing the new aluminum window: Place the new window on a flat, sturdy surface with the inside facing you, and mark the mounting holes. Next, draw marks and intermediate marks next to the center. Using a suitable drill bit, drill the mounting holes, making sure that the distance between the holes is no more than 60 cm;
- Installing the aluminum window: First, attach the insulating gaskets to the bottom of the frame. Next, apply a silicone sealant to each side of the old frame. Then you can insert the new aluminum window into the frame;
- Inserting and Tightening the First Screws: Once the window is in place, you can begin tightening the first screws. Start at the top sides, without tightening too many of the other fasteners. Then, please screw on the handle;
- Creating the outer and inner seals: In this step, use a putty knife or a flathead screwdriver to apply an insulating sealant between the old and new frames on the outside. Next, apply a silicone sealant around the frame of the new aluminum window. Now you need to apply the masking tape and smooth it out before removing it again. As for creating the inner seal, simply repeat the same process;
- Installing the Trim Profiles on the Aluminum Window: To complete the installation of your aluminum window, use a hacksaw to cut the outer trim profiles to the correct dimensions so that they cover the old frame.
