Durability to Last Decades

Unlike most sunroom additions, C-Thru sunrooms are built with independently stable and strong wall structures, so that your sunroom stays secure and endures even the toughest aspects of your local weather. Because our sunrooms don’t rely on windows or tin for their stability, they are infinitely more capable of design customization to fit the specific needs of your unique home. Best of all, our leading technology includes reinforced composite structural parts to reduce thermal expansion and contraction, properly support windows, and subsequently minimize problematic gaps so that your sunroom stays as beautiful and efficient as possible for years to come.

Sunrooms Built to Last

Our durable sunrooms are built to last and provide you with decades of enjoyment with low-maintenance care. From top-quality sunroom roofing engineered to hold up against high winds and heavy snow loads, to our insulated sunroom glass guaranteed against seal failure for 20 years, you can trust that a C-Thru sunroom will be a long-lasting and worthwhile investment for your home. Enjoy these benefits of strong design when you choose C-Thru:

3 ½ to 4 in-thick wall systems to match or surpass the quality and energy efficiency of the existing walls in your home
Thermal Cladding system to prevent inefficient leaks as well as unsightly screws and caulking
Virgin Vinyl Compound optimized for longevity and made in the U.S.
