UAS FH Construction Update for 4/04/2014
Window Wonders (April 4)
On a cold winder morning when I was a little kid, a beautiful display of frost would cover the outside edges of our kitchen window. It would make an intricate white picture frame of the weeping willow tree in our back yard. Mom put an end to the frost on our windows when she had double pain windows installed. These windows had aluminum frames, so we still got a little frost built up on the aluminum, but nothing that someone would think was pretty enough to make a post card from.
This week the Contractor installed the windows in the UAS Freshman Residence Hall and let me tell you, these are not your mother’s windows. These windows are Low E Coated, Triple Pane, Argon Filled Gap with steel reinforced uPVC Vinyl Frames by EuroLine. There will be no frost build up on these windows.
One common way of measuring the insulating value is by an R-value. The larger the R value the better it is at keeping heat inside the building on a cold frosty morning. For example here are some R-values for some common items.
· R=1.0 - Single glass pane window
· R = 1.2 - Cotton T- Shirt
· R = 1.5 - Wool Shirt
· R = 1.7 - Thinsulate Shirt
· R = 2.8 – Single Sheet of Ply Wood
· R = 3.0 - Double Pane Glass Window
· R = 5.5 - UAS Freshman Residence Window
· R = 5.5 – Two inches of EcoBatt Glasswool Batt Insulation
· R = 20.0 – Six Inches of EcoBatt Glasswool Batt Insulation
Note: For those thermodynamic engineers, the R-values above include layering effects, air film, and good dose of rounding for simplification.
The windows used for the UAS Freshman Residence Housing project has the same insulation value as a layer of Fiber Glass Batt Insulation of the same thickness. So as next year’s UAS Freshmen enjoy the fabulous views from the large windows in the Residence Hall, their parents will be glad to know their kids will remain toasty warm behind a glass window that is Low E Coated, Triple Pane, Argon Filled Gap with steel reinforced uPVC Vinyl Frames.
