The OMEGA™ sunroom line is constructed with our 3 1/2” thick insulated aluminum wall system plus 1/4" of vinyl cladding on both sides to make for a 4" thick wall. Sitting on top of your walls is our exclusive patented roof lock WeatherGuard structural insulated roof system. Available in 3", 4" and 6" thick roof panels. This allows you to design your sunroom for your particular climate. Whether it's hot and sunny most of the time or if the deep snows of winter are your concern, our WeatherGuard roof is your solution.  Designed as an efficient alternative to 'stick building' a full addition, it is the highest quality sunroom system on the market today - made available in a modular format to the Do-It-Yourselfer! Perfect for 4 season type applications.

The WeatherGuard Roof System

The WeatherGuard structural insulated roof system is C-Thru's own exclusive roof system and we manufacture our roof panels right on premises! This patented roof-lock system is available in a 1.5 lb. 3" thick EPS core panel, a 1.5 lb. 4" thick EPS core panel and a 1.5 lb. 6" thick EPS core panel. ALL panels come 4' wide.

The insulated roof panels serve three ultimate purposes...

  1. Heat transfer from the sun to the inside of your structure.

  2. Heat loss from your room in the winter months

  3. Structural load bearing roof system engineered for local, state and international building codes.

Whether it's hot and sunny most of the time or if the deep snows of winter are your concern, our WeatherGuard roof system is your solution.




C-Thru's roof has a patented snap locking system (joining the roof panels together) eliminating exposed screws and unattractive obstructions in the ceiling. Our exclusive patented snap locking system designed with internal weep channels helps prevent unwanted water from leaking in to your room. Making it hands down the industries most state-of-the-art system.





C-Thru’s patented solid insulated roof system is highly insulated, strong enough to walk on and very low maintenance. The optional "Fan Beam" can be built into any panel in your roof system. It will be installed in the 'center length' of the panel. This can be used to hand fans and install LED pot lighting while concealing all electrical wiring. Our heavy duty extruded aluminum gutter is standard!
