R-value is the resistance a material has to heat flow. The higher the R-value, the greater the resistance.

U-value is the amount of heat transferred through a material. The lower the U-value, the slower the rate of heat flow and the better the insulating quality.

The Benefits of Our Glass Offerings:

    •  Improved Comfort
    •  Less Condensation
    •  Increased Light and View
    •  Reduced Fading
Condensation, or "sweating," is a natural occurrence on all windows and is caused by excess humidity, or invisible water vapor, present in the air. When this water vapor comes in contact with a surface which is at a cooler temperature, the vapor turns to visible droplets of moisture.

Each window has many features built in to keep the temperature of the glass as warm as possible and thus reduce condensation. Our insulating glass units provide superior energy efficiency to reduce the potential for condensation. However, there is no such thing as a condensation-free window in high humidity conditions. Controlling the amount of moisture in your home is the most effective action you can take to avoid condensation.

Low E (Emissivity) Glass provides year round comfort and energy savings. Low-E is glass with a transparent metallic oxide coating applied onto or into a glass surface. The coating allows short-wave energy to pass through, but reflects long-wave infrared energy which improves the U-Value.

Low-E high-performance glass is the best way to protect your home from outside temperatures. Low-E glass prevents the warm air from escaping your glass in the winter and the cool from air escaping your glass in the summer. It will also protect your furniture and the interior of your house from sun damage.

Argon Gas is an odorless, colorless, tasteless, non-toxic gas which is six times more dense than air. It is used to replace air between the glass panes to reduce temperature transfer.

We Build. We Install. We Guarantee. We Service.
Foam filling is mostly a sales gimmick designed to make you believe it will give you the warmest window possible, and you know it works. Most people believe it, but in reality the $10.00-$30.00 you pay for it that you may know or not know about can't be recovered in actual energy savings in a hundred years. It's all hype. The hollows in a properly built window do the same thing.

Vinyl window frames offer many advantages because they require little maintenance and mold easily into almost any shape. The thermal performance of vinyl windows depends on the type and quality of the window. At least one manufacturer produces frames filled with foam insulation. Computer calculations from the laboratory test suggest that the R-value difference between foam-filled and hollow vinyl windows adds little to the overall window energy performance...

In fact, research shows that manufacturers and sales reps who claim foam-filled frames offer higher energy efficiency do so to help add structural strength to their window. With Best, you're guaranteed to get the most energy efficient window with (21) Multi-chamber design that provides superior energy performance, strong stable frames, and delivers excellent noise reduction.
