Wausau Window and Wall Systems® INvent™ -HP -XLT Series windows have received Florida’s Miami-Dade Count Notice of Acceptance (NOA), meeting the most stringent hurricane codes. Along with hurricane impact-resistance, these windows provide energy performance and recycled content to meet buildings’ goals for both sustainability and protection.

INvent-HP-XLT Series fixed, awning and project-out casement window units meet the ASTM E 1996 requirements for large “D” missile impact testing for Wind Zones 1-3 and “E” missile impact testing in Wind Zones 3-4 for essential facilities, such as hospitals. These windows were tested in accordance with Dade County Building Code Compliance Office Protocol TAS 201-94, “Impact Test Procedures;” TAS 202-94, “Criteria for Testing Impact and Non-Impact Resistant Building Envelope Components Using Uniform Static Air Pressure;” and TAS 203-94, “Criteria for Testing Products Subject to Cyclic Wind Pressure Loading.”

“The new INvent-HP-XLT product line is the perfect choice for design teams considering ‘better-than-code’ performance requirements,” notes Wausau’s health care market manager, Lisa May, LEED® Green Associate. “The widespread damage caused by Hurricane Sandy has increased expectations for storm resiliency. Invent-HP-XLT windows have been impact-tested with a very broad range of available options — such as large vent sizes, laminates, hardware types and installation accessories — to provide the functionality necessary for buildings of many different types, in warm climates or cold climates.”

Addressing energy efficiency, condensation resistance and thermal performance, the frame uses 24mm XLT polyamide thermal barriers. Helping meet Model Energy Codes, INvent-HP-XLT windows can achieve a Condensation Resistance Factor (CRF) as high as 65 per the American Architectural Manufacturers Association (AAMA) 1503 standard and a U-Factor as low as 0.34 BTU/hr.sqft.ºF per the National Fenestration Ratings Council’s NFRC 100 standard.

INvent-HP-XLT windows also are tested to meet the AAMA AW-100 Architectural Performance Class ratings, including new 910-10 lifecycle testing to 4000 operating cycles, including thermal cycling, as well as stringent requirements for air infiltration, water resistance and structural integrity.

Wausau’s INvent-HP-XLT hurricane impact-resistant windows are available with 3-7/8-inch and 4-7/8-inch frame depths. The aluminum frames contain recycled content averaging 70% or greater. Wausau’s quality-controlled, factory fabrication and glazing ensure the intended performance and accommodate dual-color finishes.

As part of the Advantage by Wausau® standard product offering, INvent-HP-XLT 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.
