How much should new windows really cost you?
Frame material, glass package and install type decide the price. Our editors on what's worth paying for.
The efficiency case
In extreme climates, triple-pane or premium low-E/gas-fill glass pays back in comfort and bills — and ENERGY STAR units may qualify for rebates. Spend on the glass package before the frame upgrade.
The install case
A perfect window installed badly leaks and fails. Full-frame replacement with proper flashing beats a cheap pocket insert in a rotted opening — match the install method to your home's condition, not just the price.
The value case
Double-pane, low-E vinyl is the workhorse spec for a reason: it handles the vast majority of drafts and heat loss without the price jump of premium materials. When you're replacing every window at once and watching the total, it's the default that leaves the least on the table.
Vinyl frames are the sensible default unless your situation says otherwise; the glass package is where climate-specific spending pays off. Install quality is the one place a discount always costs more later.
