How to Install Trimless Windows?

It's crucial to remember that installing trimless windows is challenging and calls for knowledge and experience. It is advised to hire a professional for this task, especially if you have no prior experience installing windows.

The process itself takes just several hours and the easiest approach to guarantee a properly done installation is to hire a pro from Vinyl Light.

Here are the steps on how to install trimless windows:

  • Step 1. Measurements.

The opening where the trimless window will be installed should be measured. Double-check if the opening is square and levelled.

  • Step 2. Installation of the window.

Screw the window into the surrounding wall or framing making sure it is firmly in place.

  • Step 3. Window sealing.

Apply caulking to the area around the window where it meets the wall. The seal stops the risk of infiltration of air and water through trimless windows from the exterior.

  • Step 4. Cutting drywall return.

Cut with lines from the back side of the drywall using a special knife.

  • Step 5. Attaching the return.

Keep the return 1/4-inch from the window and flush with the wall when you attach it to the underside of the upper window return. Use two drywall screws every 12 inches to secure the piece within the trimless windows interior. The screw heads must be screwed properly but not too deep.

  • Step 6. Jamb/sill installation.

While a trimless window has no casing or window trim, a window sill provides a surface that is more practical to maintain. For this, a material that won't rot or warp works well, such as composite or PVC.

  • Step 7. Finishing and cleaning up.

Add finishing touches to match the wall around it.

  • Grills. Thin narrow prolonged grills on trimless windows create a true modern look.
