Residential Window Installation

Windows of Richmond, a division of BNW Builders, is proud to bring our innovative heat mirror window technology to Richmond area homeowners looking for window installation. We’ve developed our proprietary window through decades of window expertise and good working relationships. Bruce Wiegan, owner of Windows of Richmond, has worked with Chuck Wetmore and Kensington Windows for over two decades. We stayed connected with Chuck through our relationship with Kensington Windows, which he and his ownership group purchased in 2013. After many years of working together, we approached Chuck and Kensington Windows to develop a window especially for Windows of Richmond. In 2017, The Wiegan Heat Mirror Window™ was born.

The Wiegan Heat Mirror Replacement Window Installation

Heat mirror technology is the window of the future. Since the invention of double and triple pane windows in the 1800s, window manufacturers have largely given up on developing new window innovations. While the triple pane window provides adequate insulation for most homes, it’s not a perfect solution. They’re also not very energy efficient. At the same time as we’re looking to make choices that keep our homes both comfortable and eco-friendly, current home designs are incorporating more windows, which can make it hard to control your indoor temperature. It was time for something new. With the support of the US Department of Energy, the Massachusetts Institute of Technology developed a lighter glass system that reduced energy consumption and decreased carbon emissions. Their discovery – heat mirror technology – has since become the standard for high-performance glass systems worldwide.

The New Standard For Performance Window Glass

Windows of Richmond is here to make your home more energy efficient. We’re confident that The Wiegan Heat Mirror Window™ is the most energy efficient replacement window available anywhere. These windows feature thick, insulated glass that’s been specially designed to keep your home as comfortable as possible. In many cases, these windows insulate as well as a standard wall! This additional insulation allows The Wiegan Heat Mirror Window™ to eliminate outside noise by up to five decibels, block over 99.5% of harmful UV rays, increase your home’s energy efficiency, and much more.

Customizable Windows 

Best of all, The Wiegan Heat Mirror Window™ is completely customizable. Our windows can be manufactured to fit nearly any shape or size, and with our array of design options, you’re sure to find the right choice for your home’s unique style. The proprietary paint formulation we use is available in nearly every color, can be used on both the interior and exterior frames, and comes with a twenty-year warranty on the finish. Seal failure can be a problem on many replacement windows, but not The Wiegan Heat Mirror Window™. Our dual seal glazing system offers industry-leading gas retention and moisture barriers, and will withstand temperature cycles for over 30 years. We also use fusion linked welds to bond the window’s joints together permanently, which can’t be done with wood, composite, aluminum, or fiberglass.

So, how does heat mirror technology work?

To begin, we suspend a lightweight polyethylene terephthalate (PET) film inside the airspace of dual-pane insulating class to create multiple super-insulating cavities. This provides center glass insulation performance to R-5.6, offers superior winter heating and summer cooling due to the multicavity design, and reduces condensation buildup on glass during winter. Believe it or not, it does all of this while weighing about 1/3 less than triple-pane glass.


The Wiegan Heat Mirror Windows™ delivers unbeatable performance because of the cutting edge products we use to build it. We use EcoClean foam, a USDA certified BioPreferred® product that provides energy efficient thermal performance, throughout the frames and sashes. When combined with the heat mirror glass, this foam provides unmatched comfort. We also use Sunshield PVC on the frames and sashes, which has been enhanced with titanium dioxide to block ultraviolet light.

The Wiegan Heat Mirror Window™ Design

Every step of our design process was specially developed to create the ideal product for your new window installation. You’ll notice the difference immediately. The Wiegan Heat Mirror Window™ provides superior appearance, security, and performance that increases not only comfort but curb appeal as well. Heat Mirror Technology was used to replace all 6,514 windows in the Empire State Building! 

Specially manufactured using a state-of-the-art glazing system that secures a unique kind of film between sheets of glass, Heat Mirror offers unprecedented thermal insulation and comfort in a window, while helping to protect you, your loved ones, and your cherished belongings from harmful UV rays.

Recognized by Popular Science magazine as one of the "Top 100 inventions of the Millenium," Heat Mirror insulating glass has been used around the world in state-of-the-art buildings-from single-family to high-profile projects like the Empire State Building. 

The Right Choice for Bay and Bow Windows

Bay and bow windows make a lovely addition to any home, but they’re often prone to becoming very hot or very cold. If your bay and bow windows aren’t constructed properly, they’ll struggle to control the temperature in your home. The Wiegan Heat Mirror Window™ can help. In addition to superior thermal performance and airtight seals, our bay and bow design features a unique overlap mullion design that improves water drainage, unlike traditional flat surfaces that collect moisture. We include a PVC panning system that prevents water from getting into your home.


Our bow windows are available in 3-, 4-, and 5-lite layouts, and our bay windows are available with casements or double-hung windows. In both cases, we include an internal turnbuckle chain hanging system for premium structural integrity. All windows are mounted to structural wood support for interior strength, and all exposed interior wood is protected by a rigid vinyl capping system.

If your bay or bow window has a window seat, we’ve got that covered too! Our turnbuckle chain hanging system is engineered to carry up to 800 pounds per support. To prevent the temperature control issues that bay and bow windows are prone to, our window installation seats are insulated. We go far beyond the industry standard ¾” plywood seat board in our offerings, which include:

·        Standard R9 insulated seat: This window unit adds 1” of high density foam along with a 1 ¼” hardwood veneer top cap for added insulation and comfort.

·        Deluxe R21 insulated seat: For the ultimate in comfort, this adds two more inches of high density foam. The total seat depth is 5”.


The Wiegan Heat Mirror Window™ is also available for garden windows! Our garden windows are available in premium grade, cabinetmaker quality oak and birch veneer for an elegant look that you’ll love showing off.

As you can see, The Wiegan Heat Mirror Window™ is as strong as it gets!
