How Do I Install An Oriel Window?

Installing an oriel window takes time depending on the kind of building. For new installation, it can take 1-2 hours. For replacement, it takes 2-4 hours for one window. Follow these steps below to install an oriel window.

Step 1: Measure The Existing Windows

Before you begin, it is important to check that there are no issues such as cracks. Measure the inner widths of the window from one point to another. 

Step 2: Take Out The Existing Windows

Before doing this, look at the structure to see if you need load-bearing equipment. It is also recommended that you check the sizes of the new window before taking out the existing one. 

Step 3: Measure The Angles For The Sill

Once you have removed the existing window and the building is ready to be installed, the first thing to do is measure the angles for the sill. This window comes in two different variants: 90 degrees and variable.

Ensure you give space of 1/3-inch to the window. This measurement may vary due to the angle of your oriel, so ensure you measure all corners of the bay. 

Step 4: Cut The Sill

For a lighter and easy installation, remove one of the sashes. This is because you need to put the oriel window on its head, remove the seal, cut the angle, and join the sill back. 

Step 5: Fit The Frame Adaptors

Do this to both external sides of the window before installing them. You can use 25-millimeter screws -- one at the top and the other at the bottom -- and ensure a distance of 500 millimeters when doing this.

Check the positioning well and ensure that the adaptor meets with the outer frame. If it doesn't, then the window may not sit well. 

Take extra care when screwing to the frame because the screw must not enter the sash chamber as this can affect the window's function.

Step 6: Fix The Window

Begin the installation by putting the middle bay in position and ensuring packers are included under the outer frame. Once they are all in position, use packers to level the windows. It is recommended that you start from the highest point. 

Step 7: Link The Frame Adaptor To The Bay Pole 

When the windows are level, fix the frame adaptor to the pole and ensure it is the side opposite to what you fix to the outer frame. 

Step 8: Put Fixing Screws

Once all has been done, take away the sash and fix the final screws. Let the screw go through the sill and ensure that the pole covers the screw. 

If you removed the sashes at the beginning of the installation, you could reinstall them as the frames are now in position. Check to see that they are level and that each window fits perfectly. Also, ensure that the window is working well. 

Step 9: Final Touches

Look around the window and clean everywhere to ensure no gap and all additional furniture is fixed.
