How FITFIRE®
A guarantee for professional installers:
custom results in 5 steps

Your flue is now rehabilitated!
During installation, FITFIRE® follows and adapts to every surface imperfection, restoring a new monolithic flue without joints or points where leaks could form.
Specifically, the liner is inserted into the duct and inflated with forced air and then steam: in this way, FITFIRE® perfectly shapes itself inside your old flue, like a second skin.
Since it is made with high-tech composite materials, this solution developed in Beca Engineering laboratories can adapt to all flues, creating a new duct inside them with perfect sealing against fumes and heat.
