Why Homeowners Ask: “Which Skylight Is Best?”
The growing demand for sustainable and cost-efficient home solutions has made skylights more popular than ever. In fact, according to the U.S. Department of Energy, natural daylighting can reduce lighting energy use by 50% to 80% in residential settings when combined with efficient windows and insulation.
But not all skylights are created equal. That’s where the question arises: Which skylight is best? To answer that, we must first examine the types available.

Below is a breakdown of the main skylight categories available in today’s market.

Ventilated Skylight | Can be manually or electrically opened for air flow | Kitchens, bathrooms, humid areas | $300 - $2,500 |

Choosing the Right Skylight for Your Home
When deciding which skylight is best, consider the following:
1. Roof Type
- Pitched roofs can accommodate all skylight types.
- Flat roofs often require dome or curb-mounted skylights.
2. Climate Zone
- Knoxville, TN lies in Climate Zone 4A, which is humid subtropical. Choose skylights with ventilation and UV protection.
3. Orientation
