Upgrading a Window with Interior Trim

“Upgrading an interior feature window with millwork products creates a major focal aspect for a room,” says Tina Mealer, product manager at Fypon, a manufacturer of synthetic millwork products. “Using a combination of economical mouldings, pilasters and trim to highlight an interior window is a fast project with lots of payback.”

As part of a remodeling project in Ohio, contractor Steve Roth used a combination of a Fypon window head mantel, fluted pilasters and PVC board to enhance a picture window in a den. The 10-foot wide floor-to-ceiling window covers most of the wall area in the room. Rather than simply trim out the window with casing, which he believed would not do justice to the size of the feature window, Roth selected classical architectural features to accent the window.

“The use of molded millwork pieces really saved a great deal of installation time,” says Roth. “The highly-detailed trim only needed to be cut to length and field installed. These synthetic products added fast value to the project and I was able to do the entire surround in less than two hours.”

To achieve the impressive interior surround, Roth started by measuring the full width and length around the Simonton vinyl window, then order appropriate synthetic materials.

Starting at the top of the window unit, Roth added a 10-inch high window head mantel with bottom trim. He cut the moulding returns off both ends of the mantel and fit within the wall recessed area. For this project, the mantel flushes out with the wall surface. He secured the urethane window mantel with premium adhesive and fasteners.

Roth then moved to the bottom of the window unit, measuring and installing a PVC sill on the bottom ledge of the window to serve as a base. As an option, he could also have created a sill panel out of a piece of ¾-inch PVC board for the base. Selection of a moisture-resistant, low-maintenance product is key. Again, the sill unit was installed and secured with adhesive and fasteners.

The next step was to measure out the fluted pilasters, so they fit snugly starting at the top of where the bottom trim of the window mantel starts and end at the sill. Roth cut from the base of the pilaster to fit to size. He then installed the fluted pilasters so they flank the windows and fill in spacing between the units, securing in place with adhesive and fasteners.

Roth then, slide the base cap in place over the bottom of the pilasters and secure in place. He finished the job by measuring out pieces of flat trim moulding or PVC board to fill in the areas below the windows and above the sill. Finally, he used spackling to fill all fastened heads and latex caulk to cover the seams between the wall and trim and painted the interior trim pieces with latex semi-gloss paint.

“Every person that enters this room offers a fast comment on how striking the window surround is,” says Roth.
