What is
a CeeFlow?

What is a CeeFlow? That’s a great question! Most people would say that it’s just a rooftop skylight. But when it comes to skylights that allow natural light to flood your home or office, a CeeFlow can be different things to different people.

For Architects, it is an aesthetic dream that does not pose the typical challenges associated with other skylight systems.

For Builders, a CeeFlow vis peace of mind knowing that the hole they punched into a perfectly good roof will not cause the headaches of leak chases and repairs that other skylights require.

For Consumers (Home and Office Owners), a CeeFlow is a worry-free solution that allows them to enjoy all of the benefits of harvesting natural light to use inside without worrying about the typical hassles and maintenance required with other skylight systems.

For Pete Cummings, Owner and Creator of the CeeFlow ventilated skylight system, it is where his passion for the outdoors and energy conversation meets his passion, experience, and talent for producing beautiful woodworking projects.

Regardless who you are or what you like most about the CeeFlow, one thing that everyone agrees on is the superior craftsmanship and all around performance compared to any of the typical skylight systems that are out there.

The Top 3 FAQ’s We Receive

"What are those wing-looking things on the sides?"
Functionally, they promote drainage away from the CeeFlow, significantly reducing if not eliminating potential leaks that are experienced with most other skylight systems. Aesthetically, they provide a unique visual that looks elegant while being robust in your roof!
"Why are there two sets of windows in it?
It creates a significant space barrier between the inside climate and the climate outside. This is especially important and cost-efficient when outside weather conditions are extreme.
"What is the reason why it is ventilated?"
The ventilation is an additional layer of the benefit of separating the outside climate from the inside climate. Without ventilation through the CeeFlow, the stagnant air would do a decent job of creating that barrier. When you introduce ventilation, it acts like a vacuum that ushers the change in climate that is created out of the CeeFlowinto the attic and out the ridge vent. The ventilation then becomes a vital component that sets the CeeFlow apart from it’s lesser efficient standard skylights.
