Quick response time from the vent that protects.
At left: Graph data captured from actual test. The quick response time of the intumescent coating in stopping fire ‘cold’ from reaching the attic space, due to expansion of the mesh. The blue line shows the results of a standard vent and the bottom three lines show the results of three different Vulcan Vents.
After the cells close off, they become molten and solid. Neither fire nor embers can penetrate.
The vent is designed to protect against flying embers even before mesh closure. In many cases embers will attack a home before fire ever comes near, so this feature is very important.
Did you know...
The core of our fire and ember safe vents are manufactured out of high 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 also acts as an insulator to heat, fire and embers.
As shown Below, the hexagonal coated mesh closes off at higher temperatures, sealing your home’s attic and roof from external fire.
Vulcan self-closing vent: Fine mesh screen stops ember entrance. When exposed to flames, the fire resistant coating on the inner honeycomb matrix will expand and effectively fill the space between the cells, creating an effective barrier. Also built and tested to be effective defense against ember storms.
Standard vent: Always open, with one layer of protection at most from only the largest of airborne objects. Not effective at preventing fire from entering attics and basements, resulting in an encompassing fire. Therefore not recommended or permitted in buildings near the Wildand-Urban interface.
Our vent frames are industry standard frames so there is little or no learning curve for installers & contractors. Our goal is to provide people with the vents they need to secure their homes with additional safety against wildfires and give them piece of mind from knowing that their home is protected by a product that works!
Are you claiming the Vulcan Vent will protect my house from ANY AND ALL wildfires?
No. The Vulcan Vent is a “first line of defense” against embers and exterior flame.
Can I paint the Vulcan Vents?
Yes, with caution. You should not allow paint to contact the inner matrix. Please paint the Vulcan Vents with this in mind.
Which side of the Vulcan Vent faces into the attic or crawl space?
The finer mesh side faces to the attic side or crawl space side.
At what temperature does the vent close?
The vent closes when the sustained temperature of the intumescent matrix reaches about 300 degrees C. Afterwards the closure is very fast.
What embers is the screen made to catch?
The inner screen catches embers from burning vegetation (not metals) that have enough mass capable to ignite the interior.
Where can I find the manufacturer warranty?
Yes. For details, see the warranty section on the downloads page.
Do Vulcan Vents have a patent?
