All Season Sunrooms

Bring the Outdoors Indoors Beautifully!

It’s safe to say that most of us love being outdoors. On any given day, if we had the choice to relax in front of the TV or to kick back in a comfortable chair outdoors, the answer would be a simple one. But like most of us, the thought of being outside during the dog days of summer or during the winter’s painfully cold winds and

snow, or the incessant attack of bugs the size of small pets – we will usually opt to remain indoors.

C-Thru Sunrooms is proud to offer you a beautiful solution to experience the outdoors indoors, all year round! Now you can enjoy beautiful summer and winter days, dramatic sunsets and watch the snow fall from the comfort of a new climate-controlled C-Thru sunroom!

Beautiful Curves Ahead!

C-Thru’s Curved Eave Sunrooms have become the industry standard for beauty and quality craftsmanship.

The curved eave style sunroom is truly our premier sunroom and has been a favorite for many years. The curved eave and glass adds a gentle and elegant touch with its smooth transition from walls to roof.

These beautiful sunrooms offer you nearly unobstructed views of the outdoors – whether it be a starry night or a stunning sunset.

Distinctive Design Flexibility

C-Thru’s Straight Eave Sunrooms offer a distinctive look and flexibility that are ideal for most homes and installation parameters.

Our straight eave style sunroom allows you to create a year round paradise with distinctive lines that will accentuate the existing architecture of any home.

These classic sunrooms offer you a private place of escape or a special place to entertain – depending on the mood you’re in.

What’s more, C-Thru offers several room package choices and upgrades. You can add things like ceiling fans, roof shutter systems and outdoor porch lights.

Create a Design Masterpiece

One of our most beautiful Sunrooms is the refined English Conservatory style.

These well-appointed conservatory details add a touch of class and sophistication to your Sunroom that attracts attention, engages emotion and will most likely draw a few envious comments from your friends and neighbors.

There are all sorts of reasons to choose a C-Thru Sunroom: design, quality, value, craftsmanship, durability and attention to detail. This attention to detail has resulted in our English Conservatory Sunrooms. Simply beautiful!

Breathtaking Charm & Grace

The C-Thru Garden room has all the charm and grace of our Sunrooms and features the added beauty of our highly insulated Weather-Guard roof system. Your room will remain bright and inviting, staying cooler in the summer and warmer in the winter. Your new Garden Room will quickly become the most lived in room in your entire home!

The C-Thru Garden room offers a unique feel with its gable roof design. The vaulted cathedral ceiling and the peaked front wall give a very rich and spacious impression while allowing plenty of indirect light in.

Our Garden Room is the perfect fit for those wanting a sunroom but with a little more of the “room” feeling.

A Room for Every Reason

It’s true that Sunrooms create a beautiful and dreamy retreat for you and your family. But don’t be surprised if you find yourself inhabiting your new sunroom more than any room in the house!

By day, your sunroom may become an expansive kids rec room, hobby room or home office. By night, your sunroom may quickly be transformed into a magnificent entertainment area or a romantic getaway. The uses are nearly as endless as the view on a starry night.
