Premium All Season Rooms

If you plan to use your sunroom all year long, we typically recommend an all season room (also known as a four season room). Built with state-of-the-art insulated walls, cladding, and weatherstripping, all season rooms seal out heat and cold to keep the space comfortable in any season. Like all of our sunroom additions, our four season sunrooms are custom-designed for your home’s specifications and covered by a fully transferable lifetime warranty.

Budget-Friendly Three Season Rooms

For families that prefer to use their sunroom seasonally, a three season room is the ideal choice. Although made to the highest quality standards, three season rooms are not designed for extreme temperatures, allowing for lower-cost glass panes, framing, and other materials. Because our three season rooms are tailored to your style preferences, you’ll still enjoy the same beauty and curb appeal as any other C-Thru Sunrooms addition!

Protective Patio Covers

Along with our wide array of sunroom additions, we’re also proud to install shaded patio covers that turn any outdoor spot into a sun-protected, open-air oasis. Choose from multiple roof options—including lattice, solid insulated boards, and glass—to get the right amount of shade, weather protection, and style for your intended use.

Comfort-Enhancing Enclosures for Your Pool, Patio, and More

Adding a sunroom isn’t your only option for a weather-protected outdoor living area. If you already have an outdoor feature that you’d like to enhance, consider our enclosures! Whether you want the privacy of solid walls or the sunny radiance of glass, we can enclose spaces of any shape and size.

“We’d looked at various manufacturers and various dealers around town, and the one we liked best was built by C-Thru and we have been excessively please with both of our sunrooms from C-Thru.”
