Impact Tested for Whatever Storms Throw at You

Marvin StormPlus Casement tested for 2x4 impact

Marvin Windows and Doors' StormPlus® products are designed, tested and certified for energy efficiency, driving rain, impact resistance and cyclic pressure.

  1. Test Preparation and Impact Simulation: The product is installed in a test wall and an 8' 2 x 4 is launched from an air cannon at speeds of 50' per second, depending on the code. Some codes require the product to withstand impacts to the windows center and corner.
  2. Examination: After impact, the glass is checked for holes and rips that exceed certification criteria. The glass will shatter, but its laminated layers must preserve the product's structural integrity.
  3. Pressure Cycling: The StormPlus window or door undergoes pressure cycling tests. A cycling test simulates the intense pushing and pulling forces of hurricane winds.

Reinforced Sash, Frame, and Locking Points

During a hurricane, a home's seal - its structural envelope - can be breached through a broken window or door, allowing water and wind to enter, causing an increase in pressure that can lift the roof and push the walls outward. StormPlus® offers increased protection from these potentially damaging pusshing and pulling pressures with features that include multi-layer laminated glass (protection against flying debris), reinforced sash, frame and locking points, and unobtrusive hardware reinforcements.

StormPlus Product Certification for the Toughest Codes

Marvin impact zone products are certified by the Window and Door Manufacturers Association (WDMA), Texas Department of Insurance (TDI), and the Miami-Dade Building Code Compliance Office, Product Control Division. StormPlus® product samples are independently tested to ASTM standards and TAS (201, 202, 203) protocols, and listed on the Florida and Dade County product approval websites as well as the TDI website.
