INSULATED SUNROOM

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.
Whether you’re envisioning a sunlit home office, a serene morning coffee retreat, a lush plant-filled sanctuary, a family entertainment room, or simply more living space that adds real value to your home, the Sunspace Model 400 Insulated Sunroom can be fully customized to match your vision, your lifestyle, and your budget.

BENEFITS & FEATURES

Complete Your Sunroom with ThermaDeck Flooring

For the ultimate in insulated sunroom performance, pair your Model 400 with ThermaDeck, a smart insulated flooring system engineered from the ground up to work hand-in-hand with Sunspace’s insulated sunroom solutions.
ThermaDeck creates a strong, stable base beneath your sunroom floor while significantly reducing heat transfer through the foundation. The result is a floor that feels warmer underfoot, a room that holds its temperature more consistently, and an overall living space that performs the way a real room should, even on the coldest Atlanta mornings.
It’s the ideal finishing touch for homeowners who want a complete, fully insulated solution, delivering better comfort, improved durability, and a polished, finished look from floor to ceiling.
