Insulated Sunroom | Model 400

Model 400

Enjoy Every Season in a Comfortable Insulated Sunroom

Our Model 400 Insulated Sunroom is engineered for homeowners who refuse to compromise, on comfort, on style, or on usability. Unlike 3-Season enclosures, this is a fully insulated, climate-ready living space that stays comfortable whether it’s a humid Georgia summer, a crisp October morning, or a cold January afternoon.

Protected from heat, cold, rain, and changing weather by high-performance insulated wall systems, durable roof options, and expansive glass windows, the Model 400 delivers a bright, relaxing indoor space that genuinely feels connected to the outdoors, without any of the drawbacks.
