Why Energy Armor, you ask?
• Energy Armor Windows & Doors has one of the best weather-sealing systems in
the fiberglass door industry
• Tests prove fiberglass doors exceed industry standards for insulation and air tightness
• U-Value of 0.15 (the lower the U-Value the better the insulation)
• Matching composite wood grained frames are available
• 100% CFC-free – core avoids harm to the ozone
• Climate-engineered threshold (sill) of composite construction and a fin door bottom sweep
• Seals out the weather and practically eliminates air and water infiltration altogether
At Energy Armor we want the consumer to be educated on what standard features windows are rated on. We believe in being completely up front with our customers in order to facilitate a life-long business relationship. Some competitors will provide you part of the story with numbers that are not backed up with any actual documentation other than a verbal statement by one of their representatives. For example, Company Z says that have an R-Value of 7.26. This sounds pretty good, but where does this number come from? Is it reported in writing on their literature? Website? Their manufacturer’s literature or website? If any company is not willing to put something in writing, BEWARE of their claims! In order to figure R-value, one must have the documented U-value rated by the Department of Energy. This number is then divided by 1(1/.26) and that is the actual R-value. In the above example for Company Z, their U-value as dictated by the Department of Energy is actually 0.26. This would result in an R-value of 3.58, not 7.26! This is something to be aware of and ask questions when any figures are presented. The following descriptions are provided to help you with some of the terminology:
Designates a window’s resistance to heat loss. The lower the U Factor, the better and more efficient the window is in reducing heating and cooling costs.
Measures a window’s resistance to heat loss or how well a material resists heat transfer. The higher the R-Value, the better the insulating performance.
Solar Heat Gain Coefficient measures how well as window blocks heat from the sun. The lower the number, the better the product is at blocking unwanted heat gain.
Visible Light Transmission measures how much light comes through a window. The higher the VLT, the more visible light that comes through.
Measures the amount of Ultra Violet light that is transmitted through a window that can cause fading of interior furnishings. The lower the number, the better the window is at reducing fading potential.
Here at Energy Armor, we hope to provide you with enough information to make an educated decision on your home improvement project. We offer both Argon insulating gas as well as Krypton insulating gas for your personal cost/value comparison.
The NFRC tracks the energy efficiency of consumer products and reports the efficiency rating for the entire structure of each unit. Now, our engineers have also tested the most energy efficient point of our window, which is the Center Of Glass (often referred to as COG), this is tested to have an astounding U-value of 0.11! We include this COG number as well due to the fact that window companies use this number as a marketing tool and to increase clarity of understanding, on the differences.
In addition to the energy efficiency testing, which is certainly important, another critical consideration is the fact that our window Air-infiltration Rate is the lowest in the industry at a 0.04 CFM (cubic feet per minute).
This is important because, we built this window to withstand our mid-west weather conditions and here in Nebraska, we are the 3rd windiest state in the nation, so we are happy to offer the best possible air infiltration rate in the industry!
