Enjoy Year-Round Comfort with an Insulated Sunroom By Sunspace
The Sunspace insulated sunroom is fully insulated, letting you enjoy every season throughout the year. Its thermal walls feature high-density 3″ foam panels for exceptional warmth and comfort, while heavy gauge 3″ aluminum extrusions provide strong support against wind and snow loads. The commercial-grade thermal breaks in these extrusions significantly reduce condensation and heat loss. Complementing the walls, the thermal roof system enhances wind resistance and further minimizes condensation and heat loss. ThermaDeck offers an ideal surface for carpet, tile, or nearly any flooring type, eliminating the need for costly foundation work and providing 25% better insulation than traditional flooring. All windows are fitted with double-glazed, high-efficiency Low E-Argon gas glass, ensuring added protection from the elements and consistent comfort year-round.
