I forwarded the email about Hurd's Insol8 to my Marvin rep and got this
response, for what it is worth. Obviously he has a point of view....
"I have to do some research on the energy data, but right away I
noticed this entry in the Hurd Warranty:
II. Two (2) Year Limited
Warranty: Glass Stress Cracks.
All glass units shall be free from stress cracks for a period of two
(2) years from the date of first purchase from Hurd. Glass to be supplied at no
charge. A stress crack is a crack in the glass that occurs only on the inside
lite of the window that is usually caused by a rapid change in
temperature.
Our Warranty is now 20 years on the glass, without exclusions, and pro
rating. (Hurds general glass warranty is pro-rated.)
Thanks and I'll let you know what I find out about energy claims and
comparisons.
