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
- Year-Round Comfort: The Model 400 is engineered to maintain a consistent indoor temperature regardless of the season. Insulated walls and roof systems work together to keep your sunroom warm in winter and cool in summer, so you actually use it 365 days a year.
- High-Performance Insulated Wall System: Our insulated wall panels dramatically reduce the transfer of outside heat, cold, and noise into your sunroom. The result is a noticeably quieter, more comfortable space that feels like a true interior room, not an add-on.
- Energy-Efficient by Design: The Model 400 is built with energy performance in mind. From insulated framing to thermally efficient glazing, every component is selected to support better comfort while reducing the energy load on your home's heating and cooling system.
- Fully Customizable Layouts: No two homes are the same, and neither are our sunrooms. Choose your size, window style, door placement, roof configuration, and design finishes to create a space that's entirely your own, functionally and aesthetically.
- Durable, Long-Lasting Construction: Every Model 400 sunroom is built with premium materials selected for their ability to withstand daily use and Georgia's demanding outdoor conditions. This is a room built to last decades, not just seasons.
- Abundant Natural Light: Expansive glass windows and thoughtfully designed wall systems bring generous natural light into your sunroom while keeping the elements firmly outside. Bright, open, and beautiful, all year long.
- Low-Maintenance Finish: Easy-care materials and durable finishes mean your insulated sunroom stays looking clean, fresh, and inviting with minimal upkeep. Spend your time relaxing in the space, not maintaining it.
- Adds Real Value to Your Home: A fully insulated sunroom isn't just a lifestyle upgrade, it's a genuine home improvement that increases your usable square footage and enhances your property's market appeal and resale value.
