Windows impact a building's curb appeal, energy efficiency, and property value. They also have many moving parts that operate every day, leading to wear and tear over time. Rather than buying the cheapest options that need to be replaced in 10 to 15 years, invest up front in high-performance windows that last twice as long. Plus, higher-quality windows will boost your building’s aesthetics and unit resale or rent value and provide many ways to improve quality of life.

Window replacement considerations

It’s time to look for replacement windows when the current set doesn’t function properly or has visible damage, such as a flaking or peeling frame or cracked or blemished glass. If the glass is foggy, that means the seal is broken and air is getting in between the panes. And if the windows look old, painting the frames won’t make a lasting difference without investing in replacements.

When a single window has issues, it’s easier to replace just the one, but only if you can find a new one to match the rest. Otherwise, you risk a patchwork look that diminishes your building’s curb appeal.

Factors that affect performance

Before shopping for new windows, consider your building’s specific conditions that will affect their performance. Find out the maximum solar heat gain coefficient — which refers to the sun’s heat transmitted through the glass — allowed in your area, and ensure the new set is under that. The lower the solar heat gain coefficient, the more efficient the window.

If your building runs air conditioning and management covers that cost, it’s in your best interest to invest in double-pane windows. Double-pane windows have insulating gas between the panes that help keep out heat and retain cool air, lowering electricity consumption. The extra insulation will also help with soundproofing street noise.

Frame material

Though aluminum windows are common in Hawaii, the material isn’t ideal for island weather. Aluminum eventually oxidizes and corrodes in Hawaii’s humid environment and ends up looking old. Vinyl windows are also popular because of their affordability, though they’re less customizable in terms of looks. Some people try painting them for a color upgrade, but the paint eventually peels off.

A composite or fiberglass frame is often a better choice because neither material will oxidize, peel, or blister. Composite refers to a combination of materials, such as wood and vinyl, creating a new material that offers the best of both worlds without the downsides. Pay more upfront for longevity and a quality finish, and the frame will still look new after 30 years.

Glass upgrades

Tints and etchings are available for aesthetic and practical purposes. Get a frosted or pebbled glass for a decorative look that will boost privacy at the same time. You can also invest in glass coatings to let light in but keep heat out, improving interior comfort and lowering AC bills.
