Putney, VT – Southwest
Longtime suspended coated film (“Heat Mirror”) fan and nationally recognized window expert, Sam Wharton, recently replaced windows in his Vermont home with new Alpen 525-S Series casement and awning windows.
Wharton cleverly used two different sizes of simulated divided light grids to create a custom pattern that captured the essence of the home’s original double hung windows.
In a letter to Alpen HPP, Wharton praises the air-sealing and R-value improvements gained through his use of efficient Alpen high performance fiberglass windows, noting energy improvements were significant enough to net a large cash award from his energy utility provider.
Reprinted with permission, here is his testimonial:
I am writing to thank Alpen for the amazing contribution our new HEAT MIRROR glazed fiberglass windows have made to the appearance of and, more importantly, to the performance of our home. The fenestration was a key component to the deep energy retrofit of our broad-faced cape in Putney, Vermont.
We knew that the window’s R-5 thermal performance would contribute mightily to the year round success of the building envelope, but, until our post construction Blower Door test, we had not thought all that much about the impact of the compression seal that characterizes the latched casements and awnings. We blew the doors off of the Blower Door test! The house passed with flying colors.
With an estimated Air Sealing Reduction of 58.6%, and with estimated Annual energy savings of $1,430.00, the project qualified for and we received a cash incentive from Efficiency Vermont in the amount of $2,000.00.
The strategically glazed Alpen windows were a key component of this most successful energy Energy up-grade.
Thanks, so much.
