Sunspace Model 400 - Insulated Sunroom
Enjoy Year-Round Comfort with an Insulated Sunroom By Sunspace
The 4 season sunroom by Sunspace is fully insulated, so you can enjoy the changing seasons all year round. The thermal walls are equipped with high-density 3″ foam panels for warmth and comfort, while the heavy-gauge 3″ aluminum extrusions offer strong support against wind and snow loads. Commercial-grade thermal breaks in the extrusions help minimize condensation and heat loss.
The thermal roof system complements the walls by enhancing wind resistance and reducing condensation and heat loss. ThermaDeck eliminates the need for costly foundation work and provides an ideal surface for carpet, tile, or nearly any flooring type, with 25% better insulation than conventional flooring.
All windows are fitted with double-glazed, high-efficiency Low E-Argon gas glass, providing additional protection from the elements and ensuring comfort throughout the year.
