Impact resistant louver

A louver assembly comprising:

• a) a frame;
• b) a first plurality of blades secured to the frame, the first plurality of blades being spaced apart and extending parallel to each other in a first direction, the first plurality of blades having a chevron-shape;
• c) a second plurality of blades secured to the frame, the second plurality of blades being spaced apart and extending parallel to each other in a second direction orthogonal to the first direction, the second plurality of blades having an arc-shape;
• d) wherein the louver assembly meets a minimum impact resistance test threshold and a minimum moisture penetration test threshold:
• i) the minimum impact resistance test threshold being defined as a louver assembly that prevents a projectile, weighing at least 9 pounds and having a 2×4-inch cross-section, travelling at least at 34 miles per hour, from penetrating through the louver assembly;
• and
• ii) the minimum moisture penetration test threshold being defined as a louver assembly that prevents no more than 1% of a horizontally sprayed water stream, flowing at a rate of at least 3 inches per hour, from penetrating through the louver assembly.
