Window casing on the interior of the house adds a decorative touch. I'll show you how I added it to my she shed.
– AZEK Trim White PVC Traditional Trim – Scrap 3/4″ plywood – Ryobi Brad Nailer – Level – Safety Gear: Quality Mask – Shims – Caulk: paintable – Wood glue – Miter saw – Spray foam insulation
The first thing you want to do is use spray foam insulation. Once it dries, cut away any excess pieces that might get in the way of the casing.
Now you need to add a window jamb around the whole interior of the window. Measure the depth, height, and width of the area you need to add the jamb to.
Make sure it is level, then adjust it if needed. Use wood glue and a nail gun to attach the jamb. Next measure a piece for the head jamb, and the side jambs.
You can use primed wood to save a step. Cut the bottom casing piece slightly wider than it would be with the side casings on. Make sure it is level and even with or above the bottom jamb.
Attach the trim using a brad nailer. Make sure the center of the trim piece matches the center of the window.
We made the top casing angled. We repeated the angle for both sides, and for all of the window headers. Attach with the brad nailer.
Patch any holes with paintable caulk. Once dry, tape around the window casing. Then prime the unfinished areas.
I went with a unique look and used dark gray for the casing, with the jamb pieces of the window painted pink to match my couch.
I'm so happy with how the window casing turned out! The 2 tone really gives a unique look.
