The best window options for new construction homes right now are fiberglass-frame windows with triple-pane glass, low-E coatings, and argon gas fill. These windows deliver the strongest energy performance, the longest lifespan, and the best long-term value for builders and homeowners in 2026. According to the U.S. Department of Energy, heat gain and heat loss through windows account for 25% to 30% of residential heating and cooling energy use. Picking the right windows during a new build is one of the most important decisions you will make. This article covers the best frame materials, glass options, window styles, top brands, and energy ratings so you can build smarter and save more from day one.
What Is the Best Window for New Construction?
The best window for new construction is a fiberglass-frame window with triple-pane, low-E coated glass and an argon or krypton gas fill. Fiberglass frames last 40 to 50 years or more, according to data from GlassAdvisor Research. They do not warp, rot, or expand and contract the way other materials do. That kind of stability matters in Central Oregon, where temperatures can swing from well below freezing in winter to hot, dry summers.
For new builds in Bend, Oregon, fiberglass is the top choice because it handles extreme temperature changes better than any other frame material. A report from Fixr.com confirms that fiberglass is 8 times stronger than vinyl and supports large-span windows with slim sightlines, which is ideal for modern home designs. Builders across Redmond, Sisters, and Sunriver are increasingly choosing fiberglass for these reasons.
That said, vinyl and aluminum-clad wood windows also have a place in new construction depending on the project budget and design goals. The key is matching the frame material to the climate, the home style, and the homeowner’s priorities.
Which Window Frame Material Lasts the Longest?
Fiberglass window frames last the longest, with a typical lifespan of 40 to 50 years or more. Composite frames come in second at 30 to 50 years. Wood frames last 30 to 40 years with regular maintenance, and vinyl frames last 20 to 40 years. Aluminum frames typically last 25 to 40 years but conduct heat poorly without a thermal break.
Data from Viviano Inc. and GlassAdvisor Research both confirm these ranges. The main reason fiberglass wins on longevity is its dimensional stability. It barely expands or contracts with temperature changes. That means seals stay tight, glass stays secure, and the frame holds its shape for decades.
Vinyl is still the most popular frame material in the U.S. because of its low price. But in cold-climate areas like Bend, vinyl’s tendency to expand and contract can lead to seal failure over time. For homeowners building a new home in Central Oregon, fiberglass or wood-clad options offer better long-term performance in this climate.
How Do Fiberglass Windows Compare to Vinyl for New Builds?
Fiberglass windows compare favorably to vinyl for new builds in almost every performance category. Fiberglass is stronger, lasts longer, insulates better, and handles extreme weather without warping. The one area where vinyl wins is upfront cost.
According to Fixr.com, vinyl windows average $350 to $800 installed per window, while fiberglass windows average $675 to $1,100 installed. But fiberglass lasts up to 50 years, while vinyl typically tops out at 20 to 40 years. Over the life of a home, fiberglass often costs less per year of service.
Builders in Bend and Redmond who are putting up custom homes tend to lean toward fiberglass because it handles the freeze-thaw cycles of the high desert without breaking down. Vinyl works fine for budget-conscious projects in more moderate climates, but it is not the best fit for the extremes that Central Oregon delivers.
Are Aluminum-Clad Wood Windows a Good Option for New Homes?
Yes, aluminum-clad wood windows are a good option for new homes, especially for homeowners who want the warm look of natural wood on the inside and tough weather protection on the outside. The aluminum cladding shields the exterior from rain, snow, and UV damage, while the interior wood frame adds beauty and natural insulation.
According to GlassAdvisor Research, wood-clad windows can last 40 years or more with minimal exterior upkeep. Brands like Marvin offer aluminum-clad wood windows that are popular with builders across Central Oregon because they pair well with the modern mountain aesthetic common in Bend, Sunriver, and Tetherow.
The tradeoff is that wood-clad windows cost more than vinyl or standard fiberglass. But for custom builds and high-end remodels, the design value and performance make them worth the investment.
What Are the Top 3 Window Brands for New Construction?
The top 3 window brands for new construction are Marvin, Milgard, and Andersen. Each brand offers a range of frame materials, glass packages, and custom configurations that suit different budgets and building styles.
Marvin is a premium brand known for its wood and fiberglass windows with custom sizing and high-end finishes. Consumer Reports consistently rates Marvin as one of the top-performing window brands in wind and rain resistance testing. Milgard is a West Coast favorite that offers vinyl, fiberglass, and wood options with strong warranties and reliable delivery. Andersen is one of the largest window manufacturers in the country and offers everything from budget-friendly vinyl to premium composite frames.
Lifetime Building Supply in Bend, Oregon carries both Marvin and Milgard windows, along with several other brands including Ply Gem, Simonton, and Prime Window Systems. Having access to multiple brands means builders can match the right product to each project without being locked into a single manufacturer.
Is Pella or Andersen Windows Better?
Pella and Andersen windows are both high-quality brands, but they serve slightly different needs. Pella is often praised for its built-in blinds, easy installation, and wide retail availability. Andersen is known for its Fibrex composite frames, broad product lines, and strong brand recognition.
According to the 2025 Remodeling Cost vs. Value Report, wood window replacement delivers a 70% return on investment at resale, and both Pella and Andersen offer strong wood and composite options. The best choice depends on the specific project, the builder’s preference, and the performance ratings needed for the climate zone.
For new construction in Bend, builders often choose Marvin or Milgard over Pella or Andersen because of local availability, dealer support, and product lines that are well-suited to the Pacific Northwest climate.
What Are the Latest Window Technologies in 2026?
The latest window technologies in 2026 include ENERGY STAR Version 7.0 certified glass packages, smart glass that adjusts transparency automatically, advanced low-E coatings, warm-edge spacer systems, and triple-pane configurations with krypton gas fills.
ENERGY STAR Version 7.0, which took effect in late 2023, brought the most stringent window performance standards ever. According to Andersen Windows, the Northern climate zone now requires a U-Factor of 0.22 or lower for windows, which is nearly impossible to achieve with standard double-pane glass. This has pushed triple-pane windows into the mainstream for cold-climate new construction.
Smart glass is also gaining traction. These windows adjust their tint based on sunlight levels, reducing glare and heat gain without blinds or shades. While still more expensive than traditional glass, smart glass is expected to become more affordable in the next few years.
For builders in Central Oregon, the practical takeaway is this: low-E coatings and argon gas fills are now considered baseline requirements, not upgrades. Triple-pane glass is quickly becoming the standard for any home in a cold climate.
What Is Low-E Glass and Why Does It Matter?
Low-E glass is glass with a thin, transparent coating that reflects heat while still letting in natural light. Low-E stands for low emissivity. This coating reduces the amount of heat that passes through the glass, keeping homes warmer in winter and cooler in summer.
According to the U.S. Department of Energy, Low-E windows cost 10% to 15% more than regular windows but deliver significant energy savings over time. In a 2025 survey by This Old House, more than half of homeowners who replaced their windows chose low-E coatings or similar energy-efficient features.
In Bend, Oregon, where winter temperatures regularly drop well below freezing, low-E glass is not optional. It is a basic building requirement for any energy-efficient new home.
Are Triple-Pane Windows Worth It for New Construction?
Yes, triple-pane windows are worth it for new construction in cold climates. Triple-pane windows deliver 20% to 30% better thermal performance than high-quality double-pane units, according to data published by SolarTech Online. They can achieve U-Factors as low as 0.15 to 0.20, which exceeds even the strictest ENERGY STAR requirements.
According to Ameritech Construction, triple-pane windows prevent 30% to 50% of the heat losses suffered by double-pane models. That difference shows up directly on heating bills, especially in areas like Bend, Sisters, and La Pine where winters are long and cold.
Triple-pane windows cost roughly 10% to 15% more than double-pane windows, according to House Digest. But for a new build, the added cost is small compared to the decades of energy savings and comfort. Builders who install triple-pane from the start avoid the hassle and expense of upgrading later.
The comparison between double-pane and triple-pane comes down to climate. In moderate climates, double-pane with low-E is often enough. In cold climates like Central Oregon, triple-pane is the smarter investment.
What Is the Difference Between Double-Pane and Triple-Pane Windows?
The difference between double-pane and triple-pane windows is the number of glass layers and insulating gas pockets. Double-pane windows have two layers of glass with one gas-filled space between them. Triple-pane windows have three layers of glass with two gas-filled spaces. That extra layer and gas pocket add significantly more insulation.
According to NewHomeSource, most new homes include double-pane windows as the standard, with triple-pane options becoming increasingly common in colder climates. The ENERGY STAR Most Efficient designation requires a U-Factor of 0.20 or lower, which almost always means triple-pane glass, according to the Building America Solution Center run by the Pacific Northwest National Laboratory.
Triple-pane windows also reduce outside noise better than double-pane. For homeowners building near busy roads or in neighborhoods with construction activity, that extra sound dampening is a noticeable benefit.
What Are the Window Trends for 2026?
The window trends for 2026 include black and dark-colored frames, larger glass panels for more natural light, triple-pane glass as the new standard in cold climates, slim-profile fiberglass frames, and smart glass technology.
According to Ply Gem’s 2026 trend report, dark windows in black and bronze remain the most popular color choice for new homes across the country. Matte black frames pair well with modern and contemporary home designs, which are trending strongly in custom home communities around Bend and Redmond.
Large picture windows and floor-to-ceiling glass panels are also in high demand. Homeowners want to bring the outdoors in, especially in scenic areas like Central Oregon where mountain views are a major selling point. Glass wall systems from brands like NanaWall take this trend even further by turning entire walls into operable glass panels.
Energy performance is no longer a bonus feature. It is a baseline expectation. High-performance products with low-E coatings, argon gas, and warm-edge spacers are standard in every new construction project.
What Windows Are in Style Now?
The windows in style now are large-format picture windows, slim-frame casement windows, black-frame windows, and floor-to-ceiling glass panels. Clean lines and minimal frames are the dominant look in modern home design.
According to Joyce Factory Direct’s 2026 trend report, matte black and bronze frames are leading the market, followed by earth-inspired neutrals. Interior woodgrain finishes are also trending for homeowners who want a warmer, more custom look inside the home.
In Bend, Oregon, the modern mountain home style is especially popular. This means large windows that frame mountain and forest views, with dark exterior frames that contrast against natural wood or stone siding.
How Do You Choose the Right Windows for a New Build?
You choose the right windows for a new build by evaluating five key factors: frame material, glass package, energy ratings, window style, and brand reliability. Each factor plays a role in how the windows perform, how long they last, and how they look.
Start with the frame material. In cold climates like Central Oregon, fiberglass and wood-clad frames outperform vinyl and aluminum. Next, pick the glass package. Triple-pane with low-E and argon gas is the best option for energy efficiency in Bend and surrounding areas.
Check the energy ratings. Look for a low U-Factor (0.22 or lower for the Northern climate zone under ENERGY STAR 7.0) and the right Solar Heat Gain Coefficient for your orientation and climate. A window with a higher SHGC on south-facing walls can help capture free solar heat in winter.
Choose window styles that match the home design. Casement windows offer excellent airflow and a tight seal. Double-hung windows provide a classic look. Picture windows maximize views. Awning windows work well in bathrooms and kitchens where you want ventilation even during rain.
Finally, work with a supplier who carries multiple brands and can help match the right product to your specific project. Ordering custom windows for a build takes planning, so start the selection process early.
What Is a U-Factor and Why Does It Matter When Buying Windows?
A U-Factor is a measurement of how well a window prevents heat from escaping through the glass and frame. The lower the U-Factor, the better the window insulates. It is one of the two most important energy ratings for any window, along with the Solar Heat Gain Coefficient.
Under ENERGY STAR Version 7.0, windows in the Northern climate zone must have a U-Factor of 0.22 or lower to earn certification. Oregon’s energy code requires a U-Factor of 0.30 or less for new residential construction, according to Energy Guard Windows. Meeting the stricter ENERGY STAR 7.0 standard usually requires triple-pane glass.
For builders in Bend, a low U-Factor is not just a nice-to-have. It directly affects how much the homeowner spends on heating every winter. A window with a U-Factor of 0.20 keeps significantly more heat inside than a window rated at 0.30.
What Is SHGC and How Does It Affect Your Window Choice?
SHGC stands for Solar Heat Gain Coefficient. It measures how much solar radiation passes through a window as heat. A lower SHGC means less heat enters the home from sunlight, while a higher SHGC lets in more solar warmth.
In cold climates, a higher SHGC on south-facing windows can be an advantage because it allows free solar heat to warm the home in winter. In hot climates, a low SHGC is critical for keeping cooling costs down. According to ENERGY STAR, the South-Central and Southern climate zones require an SHGC of 0.23 or lower.
For new construction in Central Oregon, builders should work with their window supplier to select the right SHGC for each wall orientation. South-facing windows benefit from a higher SHGC, while west-facing windows should have a lower SHGC to block afternoon heat in summer.
How Much Energy Do You Lose Through Old Windows?
You lose 25% to 30% of your home’s heating and cooling energy through old windows, according to the U.S. Department of Energy. In winter, that number can climb to 35% to 45% of total heat loss depending on the age and condition of the windows.
ENERGY STAR data shows that replacing single-pane windows with certified models saves homeowners an average of $101 to $583 per year depending on location and fuel type. Even replacing older double-pane windows with new double-pane low-E models can save around $134 per year on average.
In a new construction home, you have the advantage of starting fresh. Installing high-performance windows from the beginning means you never deal with the energy loss that comes from old windows. The savings start on day one and continue for the life of the home.
Do New Windows Increase Home Value?
Yes, new windows increase home value. According to the 2025 Remodeling Cost vs. Value Report by Zonda and JLC, vinyl window replacement recoups 67% to 72% of its cost at resale. Other industry estimates put the range at 65% to 80% depending on the material and local market.
The same report found that 8 of the top 10 highest-ROI home improvement projects were exterior replacements, confirming that curb appeal investments consistently outperform interior remodels. Homes with updated, energy-efficient windows also sell approximately 8% faster than comparable homes with dated windows, according to data from MrRemodel.
For new construction in Bend, starting with premium windows means the home enters the market with a strong energy profile and modern curb appeal. Buyers in Central Oregon care about energy efficiency because heating costs during long winters add up fast.
What Type of Window Lasts the Longest?
The type of window that lasts the longest is fiberglass. Fiberglass window frames can last 50 years or more with minimal maintenance, according to multiple industry sources including This Old House and GlassAdvisor Research. Composite frames are the second longest-lasting at 30 to 50 years, followed by wood at 30 to 40 years with proper upkeep.
Fiberglass earns its reputation because it does not rot, warp, crack, or corrode. It expands and contracts at nearly the same rate as glass, which keeps seals tight and prevents air leaks over time. That dimensional stability is especially important in places like Bend, where daily temperature swings between hot afternoons and cold nights are common.
Vinyl windows, while affordable, have a shorter lifespan of 20 to 40 years. In extreme climates, vinyl can become brittle from UV exposure and lose its shape from repeated thermal cycling.
What Should Builders Know About Window Lead Times Today?
Builders should know that window lead times in 2026 vary widely depending on the brand, the frame material, and whether the order is standard or custom. Standard vinyl windows may ship in 2 to 4 weeks. Custom fiberglass or wood-clad windows from premium brands like Marvin can take 8 to 16 weeks or longer.
Planning ahead is critical. For new construction in Bend, Oregon, missing a window delivery date can stall an entire project. Knowing the current window lead times and ordering early in the design phase keeps the build on schedule.
Working with a local supplier who has strong relationships with manufacturers helps. Lifetime Building Supply provides accurate material take-offs, fast quotes, and dedicated account management so builders across Bend, Redmond, Sisters, and Sunriver can plan with confidence.

What Are Casement Windows and When Should You Use Them?
Casement windows are hinged on one side and swing outward like a door when you turn a crank handle. They provide excellent ventilation and create a tighter seal than sliding or double-hung windows because the sash presses directly against the frame when closed.
Casement windows are ideal for kitchens, bathrooms, and bedrooms where maximum airflow is important. They also work well in hard-to-reach spots like above counters or sinks because the crank handle is easy to operate. For new construction homes in Bend, casement windows perform especially well because their compression seal blocks cold air drafts during winter.
How Do You Choose Between Single-Hung and Double-Hung Windows?
You choose between single-hung and double-hung windows based on ventilation needs, cleaning ease, and budget. Single-hung windows have one fixed sash and one operable sash that slides up. Double-hung windows have two operable sashes that both slide up and down.
Double-hung windows are easier to clean because both sashes tilt inward. They also allow better airflow since you can open both the top and bottom. Single-hung windows are more affordable and have fewer moving parts, which means less chance of mechanical failure over time.
For new construction in Central Oregon, double-hung windows are the more popular choice for bedrooms and living areas. Casement and awning windows are often preferred for kitchens and bathrooms.
How Does Window Placement Affect Natural Light in Your Home?
Window placement affects natural light in your home by controlling how much sunlight enters each room and at what time of day. South-facing windows receive the most consistent sunlight throughout the day. East-facing windows get morning light. West-facing windows get strong afternoon sun. North-facing windows get soft, indirect light all day.
For new construction, working with an architect or builder to plan window placement early in the design process makes a huge difference in how the home feels. In Bend, where sunny days are plentiful and mountain views are a draw, strategic window placement can reduce the need for artificial lighting and lower energy bills.
According to the U.S. Department of Energy, 76% of sunlight hitting standard double-pane windows converts to heat inside the home. Choosing the right glass package and SHGC for each window orientation helps balance natural light with heat control.
