Opening Rooflight
Have you considered ventilation?
The EOS97 is available as an electrically opening rooflight in sizes up to 4000mm in a single pane.

Aesthetics play a significant role in architectural design, and at EOS, we prioritize the seamless integration of form and function. That’s why we’ve meticulously engineered our opening system to maintain a uniform appearance, visually identical to our fixed rooflights even when closed. Unlike other systems that require a visible sub-frame for motor placement, we’ve innovatively incorporated it within our insulated upstand. This means that internally, there’s no discernible difference in depth or appearance
Allowing you to enjoy the uniform look of both fixed and opening rooflights side by side without compromising on aesthetics. With our solution, you can elevate the visual appeal of your space while enjoying the convenience and versatility of an opening rooflight system.
