Variety of Window Materials

While Ply Gem is the #1 brand of vinyl windows and one of the largest vinyl windows manufacturers in North America, the company does offer other high-quality window materials. Some of these additional window material options include the following:

• Aluminum-clad wood — offer the aesthetics of traditional wood windows with the durability of aluminum exterior cladding; also offer increased thermal efficiency and comfort


• Aluminum — offer strength and durability against inclement weather and moisture; also feature a narrow frame design that facilitates more natural light

When choosing a window material, it’s important to consider the climate where you live — aluminum-clad wood windows are ideal for cold northern climates because they offer greater thermal efficiency, whereas aluminum windows are ideal for warm southern climates because they can withstand coastal storms and won’t rot in humidity.

In addition, you’ll want to consider the style of your home before choosing a window material, as some materials offer more versatility than others.

As far as maintenance is concerned, all Ply Gem windows, no matter the material, are designed to be low-maintenance, allowing you to spend more time enjoying your home.

Energy-Efficiency

Ply Gem is partnered with ENERGY STAR to provide consumers with energy-efficient windows. Investing in energy-efficient windows can help you conserve more energy and reduce your heating and cooling costs.

Longevity and Durability

Ply Gem’s vinyl and aluminum-clad wood windows are built to last, with an average lifespan of 20–40 years. Vinyl frames resist fading, warping, and cracking, while aluminum-clad options provide additional strength in extreme weather, especially in coastal areas. Ply Gem’s windows are also crafted to withstand environmental stressors, with features like fusion-welded frames that maintain their structural integrity and Low-E glass to further enhance durability and energy savings over time.

Customizable Window Options

Alside offers customizable, durable vinyl windows with advanced insulation options, ideal for maximizing energy savings while enhancing home aesthetics.

• No Window Installation Services


• Potential for Higher Costs on Premium Materials


• Variability in Warranty Coverage Across Product Lines

No Window Installation Services

It’s important to note that while Ply Gem offers high-quality products, it doesn’t provide installation services. To install your Ply Gem products, you’ll need to find a qualified contractor in your area that is trained to install Ply Gem products.

Potential for Higher Costs on Premium Materials

Ply Gem’s premium options, such as aluminum-clad wood, generally come at a higher price compared to standard vinyl windows. While these materials offer benefits like increased thermal efficiency and durability, the higher costs may not fit all budgets, particularly for larger-scale projects.

Variability in Warranty Coverage Across Product Lines

Ply Gem’s warranty terms can differ based on the product type and materials. For example, vinyl windows typically carry a limited lifetime warranty, while aluminum-clad wood or aluminum windows may have different coverage periods. Homeowners should carefully review the specific warranty terms for each product to ensure they understand the limitations and coverage.

If you’re looking for high-quality and energy-efficient windows for your home, Ply Gem may be a top contender for your business. Ply Gem is the #1 brand of vinyl windows in the nation and the company is well-known across North America for its excellent products. 

A variety of window styles are available to meet nearly any needs and aesthetic tastes, and all window products are backed by a warranty that will protect your investment for years to come. However, specific warranty details aren’t provided on the Ply Gem website, which may be a drawback for some customers — if you’d like to learn more about Ply Gem warranties, you’ll need to contact Ply Gem and speak with a company representative.
