Two companies stand out when it comes to new and replacement windows—Kolbe and Sierra Pacific manufacture the best windows in the business.

Homeowners love the variety of sizes, styles, and options both companies offer. And the windows look great, too!

So who makes the best windows, Kolbe or Sierra Pacific? This blog post gives you an overview of both manufacturers, their products, and warranty protection to determine who provides the most value.

Kolbe VS. Sierra Pacific: A Product Overview

To make an accurate comparison, let’s take a look at two high-end products from the manufacturers: Sierra Pacific H3 composite windows and Kolbe VistaLuxe windows.

• Kolbe VistaLuxe Windows

Kolbe's VistaLuxe products offer clean lines and are a good choice for contemporary or modern homes. The exterior is made of extruded aluminum providing low-maintenance durability and boasting a clean look. The WD line features aluminum exteriors and a wood interior, giving these windows a warm and organic feel.

VistaLuxe windows have a large frame-to-daylight opening ratio. This means that they offer a large viewing area while promoting enhanced energy efficiency and thermal performance to meet local climate demands.

The durable extruded aluminum exterior is available in 44 colors and finishes and can be customized to meet a homeowner's specific needs. The warm wooden interior comes in familiar and exotic wood species. VistaLuxe interior windows are available in over 20 standard pre-finishes and are customizable.

VistaLuxe windows offer two exterior style options to match your home's aesthetic. The two profiles are flush for a streamlined, clean look with accents that add depth and visual interest. VistaLuxe windows and doors can also mimic the look of steel when finished in a dark color.

• Sierra Pacific H3 Technology

The core of Sierra Pacific windows is their advanced H3 Fusion Technology which offers the perfect combination and integration of extruded aluminum, vinyl, and wood. Its patent pending design and construction give Sierra Pacific H3 windows an industry-leading seal against the elements.

H3 windows feature a wood interior for warmth and beauty. This wood interior is fused with an extra-strong .078” vinyl base frame which offers superior rigidity, protection against rot, and better protection and resistance to air or water leakage. The vinyl components remain hidden when the window is installed.

Sierra Pacific uses extruded aluminum cladding twice as thick as other windows that use rolled aluminum cladding. H3 windows offer four innovative brick molding frames that uniquely integrate the trim, offering designer styling.

All Sierra Pacific wood and clad windows are protected with exclusive CoreGuard Plus, the best wood protection in the industry.

Kolbe VS Sierra Pacific Windows: The Details

The differences between the two manufacturers are apparent in the details. Both Kolbe and Sierra Pacific make fine products. However, Sierra Pacific offers several benefits Kolbe does not. These include:

• Color Choices

  Kolbe offers homeowners 44 color options and two exterior style options. Sierra Pacific offers 70 different color options and four exterior molding styles making Sierra Pacific windows more flexible for matching your home’s exterior style and interior décor.

• Protection

  Sierra Pacific wood & wood/clad windows are all treated with CoreGuard. This proprietary, patented process protects your windows against insects and moisture. CoreGuard is a naturally organic preservative.

• Thermal Construction

  Both Kolbe and Sierra Pacific offer various glazing options; however, it is the construction of the windows where the difference lies.

• Kolbe uses stainless steel spacers between the glazing. While stainless steel is more durable than aluminum spacers, it is not the best solution to meet the needs of Alabama homeowners. Metal spacers tend to heat up on hot summer days. Over time, this can impact the thermal efficiency of the window.

• Sierra Pacific windows use high-performance glazing and offer customizable options to meet your exact environmental and weather conditions. All insulated glass windows use No-Metal TrueWarm® Edge polymer structural foam spacers. This option dramatically improves energy efficiency and reduces seal failure, often caused by more common metal spacers.

• Glass Options

  Both Kolbe and Sierra Pacific offer several different glass options for their windows to provide optimal efficiency for Alabama homeowners. Kolbe offers several Low-E coatings and glass options, including impact-resistant and tempered glass. The Sierra Pacific family of products offers more glass, glazing, inert gas, and coating options than Kolbe.

• Finish Options

  Kolbe and Sierra Pacific offer several exterior and interior finish options for their VistaLuxe and H3 Fusion Technology windows.

• Kolbe VistaLuxe window interiors come in a variety of common and exotic wood species. The exterior extruded aluminum cladding comes in 44 different finishes and colors, including textured finishes - at an additional charge.

• Sierra Pacific H3 Fusion Technology windows also offer a large selection of wood species for the interior, and the exterior cladding is twice as thick as rolled aluminum. The interior wood surfaces are treated with Sierra Pacific CoreGuard Wood Treatment, a natural material which protects against insect damage and rot. CoreGuard Wood Treatment extends the life of natural wood. Exterior finishes include powder-coated extruded aluminum cladding for durability. There is no upcharge for textured finishes.

• Warranty

  Both Kolbe and Sierra Pacific offer warranties for their products.

• Kolbe offers a limited warranty for all VistaLuxe windows they sell. Their warranty covers their products for 10 years from the date of shipment, covering aluminum parts against defects and abnormal corrosion. It also covers insulated glass exceeding 60 square feet for 10 years, hardware, and accessories. The limited warranty is not a warranty of future performance but only covers repair, replacement, or a refund. To maintain the warranty, you must perform the recommended maintenance.

• Sierra Pacific offers the longest warranty in the industry on all of its products, including their H3 Fusion Technology. Their world-class warranty covers the exterior coating, insulated glass, and wood/clad windows for 20 years. Their limited warranty also covers exterior coatings from cracking or checking for 30 years. The Sierra Pacific limited warranty also includes 10-year parts coverage and 2-year labor coverage and is fully transferrable.

Environmental Stewardship: The Sierra Pacific Difference

The company’s commitment to sustainability and sustainable manufacturing is what sets Sierra Pacific apart. Sierra Pacific uses a business model known as vertical integration. Controlling the entire process from seed to window Sierra Pacific has created a sustainable, environmentally friendly system.

The vertically integrated model starts with Sierra Pacific owning and managing the forest land to maximize yield with minimal environmental impact. With over 2 million acres of timberland in California, Oregon, and Washington, using sustained yield forest management and timber harvesting, the company efficiently grows and uses timber. Next, the wood is harvested, processed, and prepared for use in one of 14 company sawmills in California and Washington. The lumber is then shipped to Sierra Pacific millwork facilities, where it is turned into components for their windows and doors.

The components are assembled into world-class windows and doors in one of their three manufacturing facilities. The finished products are then carefully shipped to arrive on time, and in pristine condition.

All the material from the trees is used. The fiber remaining from one process becomes the raw material for another. Shavings become animal bedding, and the bark becomes landscaping material or fuel for drying kilns and electricity generation. Using the bark and fiber as fuel, Sierra Pacific's seven cogeneration facilities produce more energy than the mills use. The extra energy is sold to California utility companies to help reduce dependence on fossil fuels.

The Bottom Line...

Kolbe makes a fine product. However, Sierra Pacific windows H3 Fusion Technology offers homeowners almost twice the color options of VistaLuxe, twice the exterior molding styles, powder-coated finishes at no upcharge, the longest warranty in the industry, and more glass and glazing options than Kolbe. Add the fact that Sierra Pacific is a third-generation, family-owned company that stands behind every window and door they sell, with a strong focus on environmental stewardship and sustainable practices, and the choice is clear!

Sierra Pacific is the right choice if you are looking for the best-looking windows and doors that offer you the most value for your dollars!
