Refreshing the facade of Houghton Academy
Houghton Academy replaced 125 aging, inconsistent windows (shown on 1st floor) with a unified look, customized to match the school's historic aesthetic using dual color finishes and high performance windows featuring Technoform's polyamide thermal barrier for energy efficiency, structural performance and long-term durability (shown on 2nd and 3rd floor).
Wausau provided T.G.R. Enterprises with its 310i Series single-hung and 4250i-XLT INvent™ Series project-out windows. Both are manufactured using Technoform’s polyamide thermal barriers, known generically as “thermal strip.” Wausau’s custom-contoured panning profile helped replicate the look of the windows’ original profile. The majority of windows also feature glazed-in grid muntins with beveled profiles to accentuate the classic appearance. Linetec painted the panning, muntins and windows’
exteriors in a Sandstone colored 70% Polyvinylidene Fluoride (PVDF) two coat, in-house blend.
“Seventy percent PVDF coatings offer the ultimate protection in building performance. These are some of the most durable coatings available,” says Linetec’s senior marketing specialist, Tammy Schroeder, LEED® Green Associate. “Their long lifecycle reduces the need for maintenance and replacement and minimizes the associated time, cost and materials.”
Houghton Academy’s windows’ Sandstone paint color matches the stonework surrounding them. Hentz explains, “I selected a color that matched the limestone. On the interior, we maintained the original wood frame, trim and sills. The woodwork is finished in this brownish olive color that is very specific to our schools. It’s practically impossible to match, so we went with a Dark Bronze on the windows’ interior finish that looks nice.”
The Dark Bronze not only is a different color, but also an entirely different finish process. Because it is an integral part of the substrate, anodize highlights aluminum’s natural beauty and metallic appearance. The anodic coating results in a hard, durable substance providing excellent wear and abrasion resistance with minimal maintenance.
Because interior and exterior components can be finished before assembly of the thermal strip system dual-color designs, or even dual finishes, can be achieved easily and efficiently. With other thermal improvement systems, dual-color, or “two-tone,” finishing involves painting one side of the material one color; then masking it off and painting the other side a different color.
Because two different finishing types were used on Houghton Academy windows – paint and anodize, any other thermal barrier method would not have been an option for this project. For two-color frame finishing using paint at the interior and exterior, Linetec estimates that Technoform’s thermal strip system painted assemblies are 400% less expensive than other thermal barrier methods that require time-consuming masking. “When the building design calls for different interior and exterior finishes, thermal strip becomes the most economical option,” says Schroeder. “When a two-tone anodize is specified – or a paint and anodize interior/exterior, like this project – it is practically impossible to accomplish with anything other than thermal strip.”
