Our Wood Windows & Doors by FABBIO DESIGN Have Now the NFRC Certification
CoorItalia is proud to announce that our Wood Windows and Doors have obtained the NFRC Certification and our main manufacturer, Fabbio Design, is now part of the NFRC database of Certified Product Directory.
The NFRC Certification: What does it mean for our products?
The NFRC (National Fenestration Rating Council) is a non-profit organization that administers the only uniform, independent rating and labeling system for the energy performance of windows, doors, skylights, and attachment products. NFRC Certification is a standard against which fenestration products can be compared in terms of energy efficiency. Nowadays this is only the only organization able to test windows and doors and verifies what their performance is when it comes to energy conservation. One of the main things they look at is how much heat is transferred through the frame and the glass (known in the trade as U-value). The lower the U-value the more energy efficient the window and door is.
The NFRC Certification: What does it mean for our customers?
There are many factors that affect the Uvalue of a unit, but it basically comes down to two main factors – the frame and the glass. There are an infinite amount of glazing choices for a home owner, from the simple single pane untreated glass with very high U-value to triple pane IG units (Insulated Glass) with heat mirrors, krypton filled and “low-e” treated surfaces which have very low u-values. Then there is everything in-between.
Your best choice between cost and performance is usually a dual pane “low-e” unit that is air filled. You can, for a small price surcharge, add Argon or Krypton to the glass for better performance. Another aspect to consider (and that the NFRC tests) is Solar Heat Gain Coefficient (SHGC). This measures how much of the sun’s rays are converted to heat inside of the room. In this case there is no “good” or “bad” value as in winter you want to heat the house but might not want to do so in the summer. Many “Passive Houses” use SHGC to great advantage to reduce their energy footprint.
