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, 4″ thick and 6″ thick EPS core panels. ALL panels come 4′ wide. The insulated roof panels serve three ultimate purposes…
- Prevent heat transfer from the sun to the inside of your structure.
- Prevent heat loss from your room in the winter months
- 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.

The fan beam will support up to a 30lb fan installation. The combination of fan beam and the weight of the fan does slightly reduce the load capacity of the individual panel.
C-Thru’s roof has a patented snap lock system (joining the roof panels together), eliminating exposed screws and unattractive obstructions in the ceiling. Our exclusive, patented snap-lock system, designed with internal weep channels, helps prevent unwanted water from leaking into your room. Making it hands down the industry’s 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.
Our heavy duty extruded aluminum gutter is standard!
