Hailstone Test
In simulated tests, VELUX skylights withstood cricket ball-sized hailstones at speeds experienced during heavy storms.
NEAT™ Photocatalytic Coating
- Silicone Dioxide/Titanium Dioxide coating reacts with UV rays to decompose surface organic dirt, reducing cleaning frequency.
- Water disperses evenly on the smoother glass surface, sheeting off and evaporating quickly to minimize water spots.
