The Benefits and Advantages

Downdraughts, smoke, leaks and animals hiding in chimneys are very common and unfortunately, difficult to deal with unless you have a cowl. If left untreated, these problems will escalate and end up in your home. Water leaks for instance, begin in the attic but spread throughout as the water goes through walls. The smoke that emanates from your chimney will wind its way back down, and since they’re toxic, presents all kinds of health problems.

With the Smart H and OH, you don’t have to put up with these anymore as the caps will ensure your chimney is clean and functioning properly. Following the installation, you can just sit back and watch as the downdraughts cease and you get nothing but up draughts. And because these cowls are stainless steel, traditional problems like corrosion and rust will no longer be a concern and neither will the ever changing weather.
