Features & Benefits

Before and after window replacement


Unbeatable resiliance to UV rays and extreme conditions.

From the Empire State Building in New York City to the Princess Elisabeth Antarctica Research Station, heat mirror windows were used to provide energy efficiency, cost savings, and protection from extreme weather conditions.

How Heat Mirror® technology works.

Experience the cutting-edge Heat Mirror technology, which employs multiple layers of thin, transparent films suspended within the airspace of an insulating glass unit. Coated with microscopic layers of metals or metal oxides, these films selectively reflect or transmit different wavelengths of light and heat.

During summer, Heat Mirror technology reflects a significant portion of the sun’s infrared radiation, keeping the interior cooler. In winter, it reflects interior heat back into the home, reducing heat loss and maintaining warmth. This dual-functionality ensures a consistent indoor temperature year-round, reducing the need for heating and cooling and improving energy efficiency. Additionally, Heat Mirror technology blocks harmful UV radiation, safeguarding furniture, flooring, and other surfaces from fading and damage. Enhancing comfort, energy efficiency, and UV protection, Heat Mirror technology is a game-changer for residential windows.

Frontline STS Interlock: Our unique Frontline STS Interlock ensures the durability of your window by securely connecting the bottom sash to the frame, keeping wind, moisture, and intruders outside.

Fortress MR Interlock: Prevent air movement and intruders from penetrating your window with our Fortress MR Interlock, which joins the moving sashes with deep interconnecting pockets that block wind and access to the locking mechanism.

100 percent satisfied with all the work done to my house. I had siding, windows , doors and gutters. The job was done quickly and on time at a reasonable cost.

I have to say my experience with BNW Builders and Bruce was exceptional. I had interviewed two other companies for replacement windows for my entire house. BNW had a better product and were the most professional and responsive. It was a clear choice to go with BNW. Now after all my 18 windows are in....we love them! What a difference in cooling and heating. I did not realize how drafty my house was until all the new windows were in. Another unexpected benefit was that it was so much quieter. I could barely hear anything from the outside.

WOW what a terrific pleasure to work with a company who was friendly, knowledgeable, punctual and professional in every way with a product that far surpassed anything that I thought it should be. From the first phone call, speaking with Bruce to working with the salesman, and Jerry the installer, it was a dream. Everything about the job was A+ and I can't recommend them highly enough. WELL DONE - I can't wait to be able to finish the rest of my house. Not only were my husband and I impressed but my neighbors and friends as well.

New exterior door installed. The workmanship was excellent and the quality of the door is also. They even came back to fix something they weren’t happy with. I wouldn’t have noticed what was wrong. Our experience is that they are great employees and an honest company.

The temperature is much ore consistent throughout the house and it is much quieter as well. Our electric bill seems to be quite a bit lower than in previous summers.

Recently I reviewed the past year of our power bill statements compared to the previous year. We averaged a 27% savings over the previous year! We had noticed that our home was warmer in the winter and cooler in the summer. Can't say enough about how happy we are with those results!

Level of initial detail from BNW Builders to define and understand the Sliding Glass Door options plus the installation process was excellent. Communication with the main office and project coordinator was also very good from Contract signing through installation. Field installation personnel were superb, being on-time, courteous, respectful to being inside of one's home, laying tarp/cloths down both inside and out, and very helpful to respond to a host of questions about the installation and product before they left. Project well done! Very trustworthy organization.

Fabulous experience! I'd give them 6 stars if I could. I had 41 windows replaced using the Infinity fiberglass windows. The installation crew was amazing. They repsected my home as if it were theirs...41 windows and not a single mistake. Great company!

They did a perfect professional job installing our windows, and the windows are excellent. We have recommended them to our neighbors here in Crossridge and they have also purchased windows from them. This is an exceptional company.

When our neighbor recently replaced his windows and put up new siding, we were so impressed with the job and the crew working there, that we immediately called BNW to do our home. Bruce was very responsive and we were able to get a quote and schedule the work within a couple days. The installation went smoothly and we are thoroughly pleased with the results. The house looks like new and is a lot quieter too with the new windows. BNW is at the top of our call list for future home improvements. Thanks Bruce!

The service was excellent! This time we had windows replaced and could not be happier. The guys installing the windows were professional and friendly. The job was completed on schedule and when they left there was not one piece of trash left behind. From start to finish I was given the impression this is a company that truly does care about the service they provide, and their clients.
