The benefits of Traditional Dome Skylights

Superior Water Management

Unlike most commercial skylights that allow condensation to collect within an interior gutter, the VELUX Dynamic Dome utilizes a fail-safe proprietary wicking system that evacuates condensation to the exterior of the skylight. We’ve also incorporated a one-piece inner frame, creating superior durability (eliminating the need for corner welds that can leak) and 50-year silicone.

Secure Thermal Seal

The VELUX Dynamic Dome incorporates an encapsulating design that provides an impenetrable water barrier with a 100 percent thermally broken skylight frame, thereby isolating interior surfaces from exterior temperatures. This 'warm design' virtually eliminates condensation while also providing a secure weather seal to the curb to impede air, water, and bug infiltration..
