Most popular
Vinyl
Affordable with solid energy efficiency, though it isn’t the best fit for every climate.
More durable
Fiberglass
Costs more than vinyl, and pays you back with greater durability, longevity, and energy efficiency.
Premium
Composite
A blend of wood with aluminum or vinyl, offering exceptional durability, longevity, and efficiency at a higher price.
Low-maintenance
Aluminum
Long-lasting and easy to care for, but not always the most energy-efficient choice.

Materials

Window frame material

Here’s a quick look at what to consider with each option.
The frame you choose shapes how your windows look, how well they hold up, and how much they help with your energy bills. There’s no single best material, only the one that fits your home, your climate, and your budget.

Vinyl is the go-to for value-minded homeowners who want solid efficiency without overspending. Fiberglass costs more up front but lasts longer and resists warping in extreme temperatures. Composite gives you the look of wood with far less upkeep, at a premium price. Aluminum is strong, slim, and low-maintenance, and works best where energy efficiency isn’t the top priority.
