Replacing roughly 60 windows in an Arizona residence is a serious undertaking, especially when one opening spans more than 20 feet and turns at a 135-degree angle. The windows had to work in the Arizona climate, accommodate the unusual geometry and handle the scale of the openings — without compromising the architecture. Find out exactly why architect Steve Baczek chose OKNOPLAST MIRU Evo Steel for the job.

Climate varies widely across the US, and windows have to handle very different conditions from one region to another.

That small NFRC label can tell you a lot about how a window will perform in a real home. U-Factor shows how well it resists heat transfer, SHGC indicates how much solar heat comes through, and Air Leakage measures how much air can pass around the window.

A window can have an impressive U-Factor and still be the wrong choice for a Passive House project.

ENERGY STAR window ratings make it easier to compare residential windows using standardized NFRC performance data.

At first glance, tilt-and-turn windows, double-hung windows, casement windows, and sliding windows all do the same job-they let in natural light, fresh air, and views.

Triple-pane windows do more than lower energy bills-they help create a quieter, more comfortable home by reducing outdoor noise.

A new front door typically costs $500 to $2,500 or more installed, depending on material, with steel the least expensive option and wood the most expensive.
