Sunspace Model 300 Sunroom – Three-Season Comfort

A Bright, Breezy 3-Season Room You’ll Use Every Day

The Model 300 is our most popular choice for Summerville homeowners seeking the perfect balance of openness and protection. This versatile sunroom offers three seasons of comfortable living while keeping out bugs, rain, and harsh sunlight.

Key Features:

Insulated aluminum posts for superior durability
Roof system with built-in gutters for seamless water management
Custom installation on existing decks or patios
Ideal for coastal living in Charleston and Summerville
Strong enough to handle wind, humidity, and salt air
Perfect for entertaining, dining, or relaxing

Whether you’re upgrading a porch, finishing a cottage space, or adding to your Summerville home, the Model 300 creates a smart, stylish expansion of your living area.

Superior Wall & Frame Construction

Unlike basic enclosures, the Model 400 features 3-inch high-density foam wall panels wrapped in heavy-gauge aluminum, delivering superior thermal insulation and structural support. These walls are designed to resist warping, handle strong wind loads, and maintain interior comfort, even during cooler months.

With commercial-grade extrusions and enhanced weatherproofing, the Model 400 creates a sunroom that feels like a true extension of your home — not just an add-on.

Therma-Deck: Superior Strength Meets Lasting Comfort

For homeowners looking to take their sunroom to the next level, Therma-Deck offers the ideal foundation system. This pre-engineered flooring platform is available in multiple insulation values — including R17 (4-1/2″), R26 (6-1/2″), and R35 (8-1/4″) — making it a powerful thermal barrier that also adds structural strength.

Built with engineered strand board panels and a high-performance insulated core, Therma-Deck eliminates the need for expensive concrete pads or foundation work. It provides a solid, weather-resistant surface that’s immediately ready for the flooring of your choice, whether that’s tile, wood, laminate, or carpet. It’s even tough enough to serve as a roofing panel in some applications.

Style That Fits Your Home

The Sunspace Model 400 is more than just efficient — it’s beautifully customizable. Choose from a wide array of door and window styles, all crafted with high-performance materials and designed for long-term reliability. With contemporary color options like White and Driftwood, your sunroom can be tailored to blend seamlessly with your home’s existing style and architecture.
