How to choose window exterior moulding

  • Material

When considering the material of the window exterior moulding, it is important to remember different materials require different types of maintenance. Moulding made of wood is a popular choice because it can be customized and painted to match the exterior of the home, but it requires regular painting to prevent rot. Cellular PVC moulding is a low-maintenance option because it is resistant to moisture and insects. However, PVC moulding cannot be painted, so the color is permanent. Fiberglass and polyurethane are other low-maintenance options that are durable and do not require painting. Consider the look of the moulding and how much maintenance the material requires before making a selection.

  • Style

The style of the moulding will greatly affect the overall look of the window. Consider the architectural style of the house and the desired aesthetic look when selecting a moulding style. Traditional-style houses may use classic moulding designs, such as crown, chair rail, or baseboard. More ornate and decorative window molding exterior, such as beadboard, wainscoting, or picture frame, may be used in formal spaces or Victorian-style homes. Also, consider the width and depth of the moulding. Thicker and more detailed moulding will make a bolder statement on the window. Thinner and more subtle moulding will provide a simple and clean look.

  • Size

The size and dimensions of the moulding will have a direct impact on the window's appearance. Consider the size of the window and the surrounding wall space when selecting the moulding size. Larger and thicker moulding works well on tall and wide windows. It will make the window a focal point in the room. However, if the window is small, oversized moulding may overwhelm the space. In this case, smaller, more delicate moulding would be more appropriate. Consider the room's ceiling height and architectural style when deciding on the moulding size. Taller ceilings can accommodate larger moulding. Shorter ceilings may benefit from thinner moulding to create the illusion of height.
