Are you looking to install an awning window with fixed glass in your home? This window type is known for its ability to provide ventilation even during light rain.
In this post, we’ll walk you through the step-by-step process of assembling and installing an awning window with fixed glass. You’ll learn how to ensure a weather-tight, functional fit with helpful tips and clear instructions.
Before you start assembling your awning window with fixed glass, make sure you have the right tools and materials on hand. Having everything ready will help you complete the job smoothly and efficiently. Here's what you'll need:
Drill with 3mm drill bit: Essential for pre-drilling holes to fix the window securely in place.
Fixing nails or screws: These will be used to attach the window to the frame. Choose according to the type of window and material.
Spirit level: This tool ensures your window is aligned properly, both horizontally and vertically.
Tape measure: For accurate measurements of the window opening and the window itself.
Hammer: A basic tool for driving nails and securing components.
Packers: These are useful for leveling the window and ensuring it's positioned correctly before securing it.
Mini pinch bar: Helps adjust the window into its final position for a perfect fit.
Staple gun and staples: If you're using flashing, this tool will help attach it properly.
A friend/second pair of hands: For larger windows, it’s much easier with someone to help hold or adjust parts during installation.
Foam corner pads and caulk: Use these for weatherproofing, ensuring no air or water leaks around the edges.
Accurate measurements are crucial for a perfect fit. Here's how you can measure your window opening to ensure your awning window with fixed glass fits perfectly.
Measure the opening height, width, and depth:
Measure at three points: both sides and the center.
Use the smallest width measurement to ensure the window fits snugly.
Add extra space:
The opening should be 20mm wider and 30mm higher than the window. This extra space allows for a square and plumb installation.
Check the depth:
Ensure the product's depth matches the cladding type where it will be installed. This ensures a smooth fit and easy installation.
Now that you have your tools ready and the window opening is properly measured, follow these steps to assemble and install your awning window with fixed glass.
Remove Old Window Frames: If you’re replacing an old window, start by carefully removing the existing frame and sashes. This will give you a clean slate for the new installation.
Clean the Opening: Ensure the window opening is free from dust, debris, or any old caulk. A clean surface ensures a better seal and easier installation.
Prepare the Blindstop: Install the blindstop on the side where the window will sit. It should fit snugly against the frame. Caulk the inner edge of the blindstop to prevent air and water leakage.
No Head Expander Needed: Unlike some other window types, awning windows don’t require a head expander. This simplifies the installation process.
No Pre-drilled Mounting Holes: These windows often don’t come with pre-drilled holes. You'll need to drill your own for securing the window to the frame. This gives you more flexibility, but make sure the holes are precise.
No Sloped Sill or Drainage: Awning windows don't have a sloped sill or built-in drainage. This means you must pay special attention to sealing and caulking to prevent water from seeping inside.
Position the Window: Carefully place the awning window into the opening. Make sure the sash is facing outward, as it will open from the top.
Secure the Window: Drill pilot holes in the frame, then screw the window into place. Use a spirit level to ensure the window is perfectly aligned horizontally and vertically. For more details, you can check ways to install awning window.
Shim the Bottom Corners: To ensure the window is level, place packers under the bottom corners. This step is essential to prevent any tilting.
Adjust the Top Corners: After shimming the bottom, adjust the top corners as well. Make sure the window is both plumb and square, which is crucial for smooth operation.
Use a Mini Pinch Bar: If necessary, use the pinch bar to gently adjust the window into perfect alignment.
Reapply the Blindstop: Once the window is secured in place, reattach the interior stops. These will keep the window in position and ensure a neat finish.
Caulk Gaps: Ensure all gaps around the window frame are sealed with caulk. This is crucial for keeping your window weather-tight and preventing drafts or leaks.
Install Operating Handle: If your awning window has a crank handle, attach it now and tighten any set screws. This ensures the handle will function smoothly when you operate the window.
When assembling an awning window with fixed glass, there are a few common mistakes that can lead to problems during installation or in the window's performance. Avoiding these mistakes will ensure a smooth and efficient installation.
Incorrect Measurements: If the window opening isn’t measured correctly, you may struggle to get a good fit. Always double-check the height, width, and depth measurements. Even small discrepancies can cause issues during installation.
Poor Sealing: Failing to properly caulk or seal around the window can lead to drafts and water leaks. Make sure to seal all gaps thoroughly, especially around the edges where the frame meets the wall.
Neglecting Plumb and Square Alignment: If the window isn’t perfectly square or plumb, it may not open or close properly. Use a spirit level to check alignment and make adjustments as needed.
Awning windows offer several advantages, making them a popular choice among homeowners. Here's why:
Ventilation in All Weather: These windows can stay open during light rain, letting fresh air in while keeping water out.
Ease of Operation: Awning windows are simple to open and close, even in places that are harder to reach, like above a kitchen sink.
Unobstructed View: The large glass panel provides a clear view of the outside, enhancing the look of your home.
These benefits make awning windows a great option, especially for improving airflow and the overall aesthetic of your home.
Assembling an awning window with fixed glass may take some time, but with proper preparation and the right tools, you can achieve a professional result. This guide ensures a smooth installation, providing your home with fresh air and a beautiful, functional window that will last for years to come.
To measure the window opening, check the height, width, and depth at three points (both sides and the center). Use the smallest measurement for the width. The opening should be 20mm wider and 30mm higher than the window for a proper fit.
Yes, you can install an awning window on your own if you follow the correct steps and have the right tools. However, it's recommended to have a second pair of hands for larger windows.
You’ll need tools like a drill, spirit level, tape measure, hammer, fixing nails or screws, packers, mini pinch bar, and foam corner pads. These tools will ensure a smooth and secure installation.
Awning windows offer great ventilation, even in rainy weather, are easy to operate (especially in hard-to-reach places), and provide an unobstructed view of the outside, enhancing the aesthetic value of your home.
Avoid common mistakes like incorrect measurements, poor sealing, and neglecting plumb and square alignment. These issues can lead to water leaks, drafts, and improper window operation.
