Vulcan Vents

The core of Vulcan Vents fire and ember safe vents are manufactured out of hi-grade aluminum honeycomb and coated with an intumescent coating made by FireFree Coatings. The intumescent coating is designed to quickly swell up and close off when exposed to high heat. The expanded material acts as an insulator to heat, fire and embers. After the cells close off they are extremely well insulated and fire or embers cannot penetrate. Even before the cells close off, the vent is designed to protect against flying embers. In many cases embers will attack a home before fire ever comes near, so this feature is very important.
