Tim:
"U"values for our windows/doors as follows:
Direct glazed (no sash) fixed windows: .24"U" value
Casement/awning windows: .30 "U" value
In-swing hinged doors: .28 "U"value
Out-swing hinged doors: .27 "U"value
Lift& slide doors: .27 "U" value
In order to achieve the above NFRC tested "U" values the glazing must be dual glazed using Cardinal 272 on the exterior
pane and Cardinal i89 glass on the room side pane with high altitude argon gas and a warm edge perimeter spacer bar.
The i89 glass is only available up to sizes of 78" x 144"or 84" x 137" so keep this in mind when designing your larger
picture windows or lift &slide doors.
If the above glass size restrictions are an issue, we can provide triple glazing which would achieve similar"U"values and
work within 96" x 137" or 84" x 144"glass sizes.The triple glazing obviously adds some weight to the operable
windows/doors and extra costs so I tend to promote the dual glazing unless the above glass sizes pose too big of a
design restriction.
Let me know if this answers your question.
On a side note, I've booked a trip to Aspen for the week of April 24-28th. I would like the opportunity to stop by your
office while I'm in town to show you more updated samples and discuss current/future work. Let me know if you'll be in
town that week and I'll call you to schedule an appointment with you and your associates.
All the best,
Eric
