Ordering custom windows for a build requires confirming rough opening sizes from verified field measurements, selecting the right frame material for the climate and design, specifying an appropriate glass package for the home’s energy zone, and locking in lead times early enough that windows arrive before framing sits idle. Every one of these decisions needs to be made before the order goes to the manufacturer because custom windows are made to order and almost never accepted for return or change once production begins. This guide covers every major specification decision builders and homeowners face when ordering custom windows, with a focus on what matters most for new construction in Bend, Redmond, Sisters, Sunriver, and the broader Central Oregon market.
You will learn how to evaluate window brands, what quality signals actually mean, how to read performance ratings, what to ask a window salesperson, and how to avoid the costly mistakes that slow down builds and create callbacks.
How to Tell if a Window Is Good Quality
You can tell if a window is good quality by checking for AAMA certification labels, inspecting the frame material and thickness, testing the operation of the sash, examining the corner joints, and reviewing the glass package specification. Quality windows have tight, precise corner joints with no visible gaps or misalignment. Low-quality windows often show uneven mitering, rough finish transitions, and corner joints that are glued rather than welded or mechanically fastened.
The AAMA gold label, issued by the American Architectural Manufacturers Association, is one of the most reliable third-party quality signals on a window. It certifies that the product has been independently tested for air infiltration, water resistance, structural performance, and forced-entry resistance. Builders who spec AAMA-certified windows have documented evidence that the products they installed meet a defined performance standard, which matters for warranty claims and inspection documentation.
Frame material thickness is another reliable indicator. Direct Door Hardware’s cross-section comparison of hardware brands shows that material thickness tracks directly with quality and longevity, and the same principle applies to window frames. Thin vinyl frames, extruded at minimal wall thickness, flex more and warp faster than thicker vinyl or solid wood frames. Aluminum clad wood windows with extruded cladding rather than roll-form cladding are noticeably more rigid and hold their finish longer. Run your hand along the frame. A quality window feels solid when you push lightly on the sash. A builder-grade window often feels hollow or slightly flexible under moderate pressure.
The glass unit matters as much as the frame. Quality insulated glass units are argon- or krypton-filled, use Low-E coatings on the appropriate surface for the climate zone, have warm-edge spacers rather than aluminum spacers, and carry a minimum 20-year seal warranty. Aluminum spacers conduct cold directly into the edge of the glass, creating condensation at the sight line and reducing the effective U-factor of the window assembly. Warm-edge spacers made from foam, rubber, or composite material reduce this thermal bridging and extend seal life.
What Is the Highest Quality Window Brand?
The highest quality window brands for residential new construction are Marvin, Andersen’s E-Series, and Pella’s Architect line, all of which sit at the top of the premium residential market for material quality, glass performance, and customization depth. Each brand has different strengths, and the best choice depends on the project’s design goals, climate requirements, and budget.
Marvin’s Signature Ultimate line uses aluminum-clad wood construction with extruded cladding, offers 14 interior wood species and more than 44 exterior colors, and is widely regarded by builders and installers as the benchmark for quality in the premium residential segment. Marvin’s Ultrex fiberglass line, available in its Elevate and Essential collections, uses a pultruded fiberglass that is eight times stronger than vinyl and significantly more dimensionally stable across temperature swings. This makes it a strong specification for high-elevation builds in Central Oregon where thermal movement between summer and winter is substantial.
Andersen’s E-Series uses thick extruded aluminum cladding over wood with nine interior wood species and more than 50 standard exterior colors. Andersen’s Fibrex composite, used in the 100 Series and A-Series, combines 40 percent reclaimed wood fiber with thermoplastic polymer, expanding 70 percent less than vinyl to reduce seal failures over time. Andersen posted $4.3 billion in 2024 sales, which reflects both its market scale and the confidence that builders and homeowners place in the brand over decades.
Pella’s Architect and Reserve lines offer aluminum-clad wood with argon-filled Low-E glass and average U-factors of 0.25 to 0.29 in standard configurations, which is well within the performance range needed for cold-climate builds in Central Oregon.
For builders in Bend and the surrounding area, Lifetime Building Supply’s window selection focuses on the brands and lines that perform best in Central Oregon’s climate and hold up to the design expectations of the custom and semi-custom segment.
What to Look for When Purchasing Windows
When purchasing windows, the most important factors to evaluate are frame material and construction quality, glass package performance ratings (U-factor, SHGC, and VT), air infiltration rating, warranty terms, lead time from order to delivery, and how well the window fits the architectural intent of the home.
Frame material sets the baseline for durability and maintenance. Aluminum-clad wood delivers the best combination of warm interior aesthetics and low-maintenance exterior protection. Fiberglass is the most dimensionally stable frame material and performs best in climates with large temperature swings. Vinyl is the most affordable and lowest maintenance, but offers fewer finish options and is more vulnerable to warping in dark colors under direct sun. The U.S. Department of Energy reports that windows account for 25 to 30 percent of residential heating and cooling energy use, which means frame material choice directly affects long-term operating costs.
Glass package performance is quantified by three primary ratings. The U-factor measures how quickly heat passes through the window assembly, with lower numbers meaning better insulation. For Central Oregon’s cold winters, a U-factor of 0.30 or below is the right minimum target, with many premium builds specifying 0.25 or lower. The Solar Heat Gain Coefficient (SHGC) measures how much solar energy the window admits. In Bend’s sunny high-desert climate, a moderate SHGC of 0.25 to 0.40 on south-facing windows captures useful winter solar gain without overheating in summer. Visible Transmittance (VT) measures how much visible light passes through, with higher numbers meaning brighter rooms.
Air infiltration rating measures how much air leaks through the closed window under standard test pressure. Lower air infiltration means less drafts, less moisture intrusion, and better thermal performance in cold weather. A rating of 0.01 CFM per square foot or below is the standard for quality residential windows.
What to Ask a Window Salesperson
When talking to a window salesperson, ask these specific questions before committing to any order: What is the U-factor, SHGC, and air infiltration rating of this product for my climate zone? Is the cladding extruded or roll-form? What is the frame depth, and will it accommodate my wall construction? What is the current lead time from order confirmation to delivery? What does the glass seal warranty cover, and for how many years? Is the glass warranty transferable if the home is sold? Can the exterior color and interior species I want be combined in the same order, or are there restrictions? What happens if a unit arrives damaged?
These questions separate suppliers who know the product from those who are relying on catalog language. A knowledgeable salesperson can answer each of these without hesitation. Vague answers about U-factors, lead times, or warranty coverage are a signal to get more specific information in writing before signing anything.
Frame depth is a particularly important question that is often overlooked. Standard 2×4 wall construction typically requires a frame depth of at least 3.25 inches. Homes built with 2×6 walls or with additional exterior insulation need deeper frames to sit flush with the finished wall surface. Ordering the wrong frame depth creates installation problems that cannot be corrected without returning the window, which costs weeks on a tight build schedule.
For builders managing complex multi-window orders on new construction projects in Bend and across Central Oregon, the team at Lifetime Building Supply reviews every specification detail before the order goes to the manufacturer, which is exactly the kind of oversight that prevents expensive errors.
Is Pella or Andersen Better for New Construction?
Pella and Andersen are both excellent choices for new construction, and neither is universally better than the other. The right choice depends on the design requirements of the specific project, the budget, and which product line within each brand is being compared.
Andersen is often the better choice for builders who want a wide material range, a strong transferable warranty, and broad product availability. Andersen’s 400 Series is one of the most widely installed windows in American residential construction, which means installers are familiar with it and replacement parts are easy to source. Andersen’s E-Series is its premium aluminum-clad wood line with the deepest customization. Andersen’s transferable warranty adds resale value that buyers notice when they purchase a home.
Pella tends to win on entry-level affordability and design flexibility for architects who want precise profile options to match a specific architectural style. Pella’s Reserve line, which was formerly the Architect Series, uses aluminum-clad wood with a U-factor range of 0.25 to 0.29, making it a strong performer in cold climates. Pella also offers showroom access through Lowe’s locations, which makes it accessible for homeowners who want to see products in person before specifying them.
For custom homes in Sisters, Sunriver, and the surrounding Central Oregon mountain communities, the choice between Pella and Andersen often comes down to which product line the builder has established a supply relationship with and which supplier offers the most accurate material takeoff and pre-order review service. Both brands perform well; the supplier relationship determines how smoothly the order process runs.
Is .27 a Good U-Factor for Windows?
Yes, .27 is a good U-factor for windows and is appropriate for most new construction builds in Central Oregon’s climate zone. A U-factor of 0.27 means the window assembly allows 0.27 British Thermal Units (BTUs) to pass through each square foot per hour per degree of temperature difference. For reference, ENERGY STAR’s most stringent Northern climate zone requires a U-factor of 0.22 or below, while the Northern zone standard is 0.27 or below. A window at 0.27 meets the top tier of ENERGY STAR residential certification for the northern U.S. climate zone.
For most homes in Bend and Central Oregon, a U-factor of 0.27 to 0.30 is appropriate for double-pane windows with argon fill and Low-E coating. Builders who want to push further can specify triple-pane windows with U-factors of 0.15 to 0.22, which delivers meaningfully better insulation at higher elevations and on north-facing walls where heat loss is greatest in winter. For more context on whether triple pane is worth the added cost in Central Oregon’s climate, the comparison between double-pane and triple-pane windows covers the key performance and cost tradeoffs in detail.
What Are the Top 5 Window Companies?
The top five window companies for residential new construction in the United States, based on quality, brand recognition, and builder adoption, are Marvin, Andersen, Pella, Milgard, and Sierra Pacific. Each company serves a somewhat different segment of the market, and builders often work with more than one brand depending on the project type and price point.
Marvin is widely regarded as the premium benchmark for aluminum-clad wood and fiberglass windows, with unmatched customization and finish quality. Andersen is the largest window company by volume and offers the broadest product range from builder-grade to luxury. Pella serves a similar market to Andersen with strong design flexibility and competitive pricing at the mid and upper tiers. Milgard is a strong choice for the Western U.S. market, including Oregon, with its Tuscany vinyl line and Trinsic aluminum line, both of which are engineered for Pacific Northwest and high-desert climates. Sierra Pacific is particularly well-known in the Pacific Northwest and offers aluminum-clad wood windows competitive with Marvin and Andersen’s premium lines at a price point that resonates with builders in the region.
For Central Oregon builders, Marvin and Sierra Pacific have the strongest regional presence and are frequently specified on custom homes. Milgard’s Trinsic line is a popular specification on contemporary design projects in Bend where the narrow aluminum frame profile suits the modern aesthetic.
A detailed side-by-side look at two of the most commonly compared brands in this region is available in the Marvin vs. Milgard comparison, which covers performance, pricing, and best-use applications for Pacific Northwest and high-desert builds.
Are Jeld-Wen Windows Good Quality?
Jeld-Wen windows are good quality in the mid-range residential segment, though they are not on the same level as Marvin, Andersen E-Series, or Pella’s top lines. Jeld-Wen is a large manufacturer with a broad product line that spans from builder-grade vinyl to aluminum-clad wood windows in its Siteline EX series. The Siteline EX is their highest-quality offering, featuring aluminum-clad wood construction with a U-factor range competitive with Pella and Andersen’s mid-tier lines.
Jeld-Wen’s reputation among builders varies significantly by product line. The builder-grade vinyl lines are widely used on production housing where cost is the primary driver. The Siteline EX and W-2500 aluminum-clad wood lines receive much stronger reviews from contractors and architects who compare them to Marvin Integrity or Andersen 400 Series at a similar price point. Jeld-Wen was acquired by an investment firm in 2012 and went through a period of quality consistency issues that affected its reputation in the custom home segment. More recent product lines have improved significantly, but builders in Bend and Central Oregon who work in the premium segment tend to specify Marvin, Sierra Pacific, or Andersen over Jeld-Wen when design quality is the primary criterion.
What Is the 25 Percent Glazing Rule?
The 25 percent glazing rule is a general guideline from energy modeling and building science that recommends window area not exceed 25 percent of the home’s floor area to keep heat loss and solar gain within manageable ranges for most climates. This guideline is used in energy code compliance calculations and passive solar design. Homes with window-to-floor area ratios above 25 percent face significantly higher heating and cooling loads, which must be offset by higher-performing glass specifications or additional mechanical system capacity.
In practice, the 25 percent rule is most relevant for designers and builders who are working toward ENERGY STAR Home certification or pursuing a specific energy performance target. Many custom homes in Bend and Sunriver exceed this ratio because open, light-filled interiors are part of the design brief. When a home has a high window-to-floor ratio, the glass specification becomes even more critical. A U-factor of 0.30 that is adequate for a home at 15 percent glazing may be insufficient to meet energy targets in a home at 30 percent glazing without compensating with better insulation elsewhere in the building envelope.
Understanding how SHGC works alongside U-factor is essential when specifying windows for a high-glazing home. South-facing windows with a higher SHGC can offset winter heating loads through passive solar gain, while east, west, and north windows generally benefit from a lower SHGC to reduce unwanted heat gain in summer. The page on what SHGC is and how it affects your window choice covers this in the context of Central Oregon’s specific solar angles and seasonal patterns.
What Is the New Trend for Windows?
The new trends for windows in residential construction are larger glass areas with slimmer frames, dark exterior finishes particularly matte black and dark bronze, casement and awning windows in place of double-hung on modern and contemporary homes, multi-slide and stacking glass wall systems on indoor-outdoor living spaces, and triple-pane glass on high-performance and net-zero oriented builds.
Slim-frame windows, including aluminum and aluminum-clad designs with narrow sight lines, are growing in popularity on modern and contemporary homes across Bend and Sisters. Buyers in the premium market want maximized glass area and minimal frame interruption. Brands like Milgard’s Trinsic series and Marvin’s Modern line are designed specifically around this aesthetic and are increasingly specified on architecturally driven new construction.
Dark exterior finishes have shifted from niche to mainstream. Matte black and dark bronze aluminum clad windows are specified across a wide range of home styles, from modern farmhouse to contemporary mountain architecture. Ply Gem and other manufacturers note that dark exterior colors driven by social media and design publications are now shaping homeowner expectations, and builders who do not offer these options are losing projects to those who do.
Glass wall systems, including multi-slide, lift-and-slide, and folding systems, continue to grow as a specification in high-end custom homes where the boundary between interior and exterior living is a central design goal. These systems require careful structural planning and proper glazing specifications for the local climate, but deliver a visual impact that no standard window can match. Glass wall systems at Lifetime Building Supply cover this category for builders and architects in Central Oregon.
What Is the R Value of a Window?
The R-value of a window measures its resistance to heat flow, with higher R-values indicating better insulation. R-value is the inverse of U-factor: R = 1 / U-factor. A window with a U-factor of 0.30 has an R-value of approximately 3.3. A window with a U-factor of 0.20 has an R-value of 5.0. For context, a typical 2×6 insulated wall assembly has an R-value of 19 to 21. Even the best triple-pane windows reach only R-6 to R-10, which means windows are always the weakest thermal point in any wall system.
Cornell University’s housing fact sheets on moisture and condensation confirm that a single-pane window has an R-value of approximately 1, while a standard double-pane window has an R-value of approximately 2. Premium double-pane windows with argon fill, Low-E coating, and warm-edge spacers achieve R-3 to R-4. Triple-pane windows with krypton fill reach R-5 to R-8 depending on the configuration.
For builders in Central Oregon’s colder communities, particularly La Pine and the Sisters area where winter temperatures drop well below freezing for extended periods, the difference between R-3 and R-5 glass is meaningful for both comfort and heating costs. The page on what a U-factor is and why it matters covers both ratings in depth and helps builders choose the right performance target for each project’s climate zone.

Frequently Asked Questions About Ordering Custom Windows for a Build
What Is the Cheapest Time of Year to Buy Windows?
The cheapest time of year to buy windows is typically late winter, specifically January through March, when demand from contractors is lower and some manufacturers and dealers offer promotional pricing to fill order backlogs. Fall, particularly October and November, is a secondary window for lower pricing as the busy summer construction season winds down. For custom windows on new construction projects in Bend and Central Oregon, timing the order to take advantage of slower periods can sometimes produce pricing flexibility, but lead times from premium manufacturers like Marvin and Andersen are not necessarily shorter in the off-season. Ordering early enough that the windows arrive before the build needs them is always more important than chasing seasonal pricing.
Are Andersen Windows Sold at Home Depot the Same as Renewal by Andersen?
No, Andersen windows sold at Home Depot are not the same as Renewal by Andersen. Andersen Windows and Doors is the main brand, sold through dealers and building supply companies. Renewal by Andersen is the company’s dedicated replacement window division, which sells, manufactures, and installs a distinct product line using Fibrex composite frames. Home Depot carries standard Andersen product lines, including the 200 Series and 400 Series, which are different from Renewal by Andersen’s product lineup. For new construction in Bend and Central Oregon, builders typically work with Andersen’s dealer network rather than big-box retail to access the full product range and to get accurate material takeoffs and lead time management that a specialty supplier provides.
Which Is Better: Andersen 200 or 400 Series?
The Andersen 400 Series is better than the 200 Series for most new construction applications. The 400 Series uses wood interiors with vinyl-clad exteriors and offers significantly more style, size, and configuration options than the 200 Series, which is a more limited builder-grade line. The 400 Series carries stronger energy performance ratings, more finish choices, and a broader warranty. For custom homes in Bend, Redmond, and Sisters where the window package is a selling point and a reflection of the home’s quality level, the 400 Series is the minimum appropriate specification from the Andersen product family. The E-Series, with its aluminum cladding and nine interior wood species, is the premium tier above the 400 Series for projects where appearance and customization are the highest priorities.
Can You Negotiate Window Prices on a New Build?
Yes, you can negotiate window prices on a new build, particularly when ordering a complete window package for an entire home rather than individual units. Builders and contractors ordering multiple windows at once have meaningful leverage because the order volume justifies pricing discussions that a single-window buyer does not have. Getting competing bids from multiple suppliers is the single most effective negotiation tool. Real-world experience from new construction projects documented on homebuilding forums shows that brands including Marvin, Andersen, and Jeld-Wen have reduced quotes by 15 to 25 percent when buyers communicated that they had competing bids in hand. Specialty dealers like Lifetime Building Supply, who provide accurate material takeoffs and deep product knowledge, often provide competitive pricing on complete packages as part of building a supplier relationship.
Is JELD-WEN a Chinese Company?
No, JELD-WEN is not a Chinese company. JELD-WEN is an American window and door manufacturer founded in 1960 in Klamath Falls, Oregon. It is headquartered in Charlotte, North Carolina, and operates manufacturing facilities across the United States, Canada, and internationally. JELD-WEN was taken private by Onex Corporation, a Canadian private equity firm, in 2011, and went public again in 2017. Despite its international manufacturing footprint, JELD-WEN is an American-founded and American-headquartered company with significant domestic production. The company has faced quality consistency concerns over certain product lines in certain periods, but it is not a Chinese company.
Is JELD-WEN Shutting Down?
As of the time this article was written, JELD-WEN has not announced a full company shutdown, though the company has gone through significant restructuring. JELD-WEN announced in 2024 that it was exploring a potential sale of its North American operations and closing or consolidating some facilities as part of a broader cost-reduction plan. This has created uncertainty about certain product lines and lead times from some of their manufacturing plants. Builders and homeowners in Bend and Central Oregon who are considering JELD-WEN products should confirm current product availability and lead times directly with their supplier before specifying JELD-WEN windows on a new build. For the most reliable supply and warranty support on custom home projects, working with established brands through a dedicated specialty supplier is the safest approach.
What Should Builders in Bend Know Before Ordering Custom Windows?
Builders in Bend and across Central Oregon should confirm four things before placing any custom window order: verified rough opening measurements taken from the actual framed structure rather than architectural drawings, a glass package specification that matches Central Oregon’s climate zone (U-factor 0.30 or below, Low-E, argon fill as minimum), lead time from the manufacturer that fits within the construction schedule with at least two weeks of buffer, and warranty documentation confirming glass seal coverage for a minimum of 20 years. Custom windows are made to order and cannot be returned once production begins, so getting the spec right before the order is placed protects both the builder’s schedule and the client’s investment. The team at Lifetime Building Supply reviews every specification detail and performs accurate material takeoffs before any order is submitted, which is the kind of pre-order diligence that prevents the most common and costly ordering mistakes.
Final Thoughts
Ordering custom windows for a build is a multi-layered decision that touches frame material, glass performance, measurement accuracy, lead time management, brand selection, and warranty coverage. Getting any one of these wrong creates delays, callbacks, or long-term performance problems that cost more to fix than they would have cost to get right the first time. The most important step is always verifying field measurements before the order goes in, because no amount of product quality recovers a window ordered to the wrong size.
For new construction projects in Central Oregon’s climate, prioritize a U-factor of 0.30 or below, Low-E glass with argon fill, AAMA certification, and a glass warranty of at least 20 years. Choose frame material that fits the design intent: aluminum-clad wood for premium aesthetic quality, fiberglass for maximum dimensional stability, and vinyl where budget is the primary driver. Order early, confirm lead times in writing, and work with a supplier who reviews specifications before submitting them to the manufacturer.
The team at Lifetime Building Supply serves builders and homeowners across Bend, Redmond, Sisters, Sunriver, and La Pine with accurate material takeoffs, expert product guidance, and white-glove delivery that keeps projects on schedule. From initial specification through final delivery, Lifetime Building Supply is built to support every stage of the window ordering process on new construction projects across Central Oregon.
