Trusted by roofing professionals across Canada, the VMAX CT-4 is of the best quality roof exhausts on the market. Designed to discharge kitchen range hoods, bathroom fan and dryers, the built-in damper opens to release the exhaust air and closes, creating a hermetic barrier with the outside, thus reducing your energy bills. The built-in deflector will prevent any back drafts and clapping of the damper while also deflecting the flow towards the sides of the unit, reducing the risks of melting snow and ice dams. The VMAX CT-4 is built from galvanized steel making it completely rodent proof. Its unique design allows the exhaust air to be directed upwards for an optimal diffusion into the environment. This differs greatly from the common roof exhausts which discharge directly onto the roof leading to odours being impregnated in the roof materials and in time may attract rodents. The VMAX CT-4’s unique height design also reduces risks of infiltration of any kind.
