The frames of your replacement windows come in a variety of materials. The most common options include:

- Wood
- Vinyl
- Aluminum
- Steel
- Fiberglass
- Combinations of these materials

Many window providers specialize in just one type of frame material. For example, Deluxe Windows focuses exclusively on vinyl frames. If you’re looking for a specific frame type, it’s a good idea to ask your provider about available options before scheduling an appointment. This can save you time by ensuring the company offers what you need.

Wood frames

Wood is the most traditional material for window frames and remains a popular choice thanks to its versatility.

Hardwood is durable and can be oiled, painted, or left untreated for a natural finish.
Softwood is less durable but more affordable. It must be painted or sealed and generally requires more maintenance than hardwood.

Pros: Natural beauty, timeless style, good value
Cons: More expensive than other options, requires regular maintenance

‍

Vinyl frames

Vinyl is a low-maintenance and cost-effective alternative to wood. It’s available in various finishes and colors and offers solid insulation against both heat and sound.

Pros: Typically 25% cheaper than wood, easy to care for, wide range of color options
Cons: Quality varies by manufacturer; colors can fade over time

Aluminum frames

Aluminum window frames are durable, lightweight, and easy to maintain. Thanks to their strength, they’re often used to support large panes of glass. However, aluminum conducts heat easily and may be more susceptible to condensation issues.

Other less common frame options include fiberglass, aluminum with a wood core, or hybrid constructions combining wood and steel.

Window cladding: the low-maintenance wood solution

As mentioned earlier, wood frames need consistent upkeep to stay in good condition. Without regular staining or painting, wood may swell in humid climates, and prolonged exposure to moisture can lead to warping, rotting, or mold.

To enjoy the look of wood without the high maintenance, many homeowners choose cladded windows. Window cladding involves covering the exterior side of a wooden frame with vinyl or metal. This protective layer shields the window from the elements, while the interior side remains exposed wood—providing the warm, natural look inside your home.
