As the most recent addition to the INvent Series, Retro windows feature a narrow, beveled exterior face that replicate the look of classic steel and wood windows, while offering modern, high performance.
Helping meet Model Energy Codes, INvent Retro XLT windows with double insulating glass can achieve a U-Factor as low as 0.39 BTU/hr.sqft.ºF and a Condensation Resistance Factor (CRF) as high as CRF Frame 60/CRF Glass 70. Triple insulating glass further enhances energy savings and condensation resistance.
"High-performing, historic-looking window systems are essential to meeting today's commercial building needs. The majority of our built environment already has been constructed, is aging and is in need, or will soon be in need of renovation. In addition, many newly constructed buildings are seeking to match an existing aesthetic within their neighborhood and on their corporate, medical, governmental or educational campuses," says Wausau's vice president, Steve Fronek, P.E., LEED® Green Associate. "INvent Retro helps accomplish both design and performance criteria."
Addressing weather-ability, durability and thermal performance, the frame uses 18mm and 24mm XLT polyamide thermal barriers. These windows also are tested to meet AAMA AW-100 Architectural Performance Class ratings, including new AAMA 910-10 lifecycle testing to 4000 operating cycles and stringent requirements for air infiltration, water resistance, life cycle testing and structural integrity.
Contributing to renovation projects' green building goals, all of Wausau's windows are manufactured using a high percentage of recycled content. The aluminum frame may be specified in 2-7/8, 3-7/8 and 4-7/8 inch depths with optional equal sightlines at vents and fixed lites. Low-profile fixed framing to maximize daylight openings also is available. Snap-in grid muntins or low-profile true divided lite muntins, and a broad selection of renovation panning may be added to emphasize historic styling.
Configurations for 2250i Retro XLT include fixed, in-swing and out-swing casements, top-hinged, awning and hopper vents. Project-in French casements without a center rail may be requested for terraces, Juliet balconies, and ground floor applications. Multi-lock hardware can be ordered for improved accessibility.
Operable units present a seasonal opportunity for natural ventilation. Integral between-glass blinds minimize maintenance, while managing light and glare. Combined with the advantages of natural light, outside views and thermal performance, these qualities may aid buildings seeking certification under such programs as the U.S. Green Building Council's LEED Green Rating System™.
Wausau's INvent Series' quality-controlled, factory fabrication ensures the intended performance and accommodates dual-color finishes. With a palette exceeding 30,000 color choices, Wausau's painted finishes may be requested as liquid or powder coatings with ultra-low volatile organic compounds (VOC) and VOC-free content. Durable, VOC-free anodize finishes, such as copper color that does not patina, complement the historic aesthetic.
As part of the Advantage by Wausau® standard product offering, these high-performance windows are pre-engineered and factory-glazed. Available on an accelerated delivery schedule, these competitively priced windows are backed with an industry-leading warranty of up to 10 years.
