FAQ
Is ceramic light enough to be used in ductwork made from very light gauge metal?
Ceramic is approximately half the weight of steel. It can be supplied as thin 1/8" ceramic lining equivalent to 16-gauge steel.
What does a typical ceramic installation involve?
Ceramic installation is typically straightforward, but it is important to have a good clean surface to bond to. Saint-Gobain Performance Ceramics & Refractories can recommend several types of adhesives or mortars depending on application operating temperature, and teams of qualified and experienced specialists are on hand to evaluate customers’ current systems before making a recommendation on the potential use of ceramics.
