Wausau's new 4250i and 4250i-XLT INvent Series features offset glass planes to replicate double-hung sash, while providing the ease of operation, durability and low air infiltration of projected windows.
Contributing to renovation projects' green building goals, all of Wausau's windows are manufactured using a high percentage of recycled content. As part of the Advantage by Wausau® standard product offering, these high-performance windows are pre-engineered and factory-glazed. Addressing weather-ability, durability and thermal performance, the 4.5-inch frame uses a polyamide thermal barrier. Low U-Factors allow broad expanses of vision glass to meet Model Energy Codes.
INvent Series' durable products are tested to meet AAMA AW-100 Architectural Performance Class ratings, including new AAMA 910-10 lifecycle testing to 4000 operating cycles. Unlike double-hung windows, there are no counter-balancing mechanisms to maintain or replace. Available on an accelerated delivery schedule, these competitively-priced windows are backed with an industry-leading warranty of up to 10 years.
For enhanced energy savings and condensation resistance, triple glazing and extra-wide thermal barriers may be specified. Hurricane impact and blast-hazard-mitigating designs also may be specified. Wausau's INvent Series' quality-controlled, factory fabrication ensures the intended performance and accommodates dual-color finishes.
