Window Frame Material Types

Fiberglass Window Framing

Fiberglass window frames are a good choice and at the top of the list for promoting high-energy efficiency over other materials such as metal-clad wood frames, PVC and aluminum. Not only is the material durable, long lasting, and energy efficient, it is comprised of one of the most plentiful natural resources on the planet—sand. Fiberglass is a blend of glass particles, which is comprised of sand, and held together by resin.

Fiberglass window frames look nice and require little maintenance. When considering fiberglass, look for frames that contain foam insulation within the frame cavities to ensure the best results in energy efficiency. Fiberglass wood framing carries a very high “R” value determined by the U.S. Department of Energy (DOE). This rating measures the amount of heat loss, heat gain, and the material’s ability to resist air leakage. Fiberglass frames combined with energy efficient insulated glass provide property owners with the optimum in energy savings. On the downside, fiberglass material is not as eco-friendly as wood frames when it comes to recycling.

Vinyl Window Framing

Vinyl is one of the most popular window framing options. It is available in a variety of colors giving property owners plenty of options for exterior beautification. Vinyl is also weather resistant, easily installed, and requires very little maintenance. Vinyl window frames are durable and have a long life span. When it comes to being eco-friendly, the window frames are considered a green product because the material can be recycled.


Wood Window Framing

The aesthetic of wood window frames is a popular choice especially for homeowners who like a warm and classic look to their home’s exterior. Wood is a natural resource, is recyclable and considered to be an eco-friendly material if certified. If you choose wood framing, purchase a product that has been approved for use by the U.S. Forest Stewardship Council.

While wood framing is beautiful, it is not recommended for areas that sustain extreme inclement weather such as snow, ice and rain which can lead to moisture retention and frame damage. Wood framing can be expensive and require more maintenance than vinyl or fiberglass, but it is worth the investment if you live in a climate-friendly region.

Aluminum and Composite Window Framing

While aluminum window frames are inexpensive and require minimal maintenance, the material conducts heat, making them less efficient. Composite frames are constructed using a blend of assorted materials. These include items such as metal, wood and vinyl. With composite window frames, discuss the options with the sales representative about each manufacturer and the rating of their product. The cost, energy-efficiency, and level of eco-friendliness can vary from manufacturer to manufacturer.

Benefits of Eco-friendly Window Framing Materials

  • Energy efficiency for your property when properly installed and insulated
