Quality Materials

FireStorm® Ember Mesh is made out of 304 Stainless Steel making it the best choice for those who want a durable material.

Built to Resist Wildfires

Firestorm® Ember Mesh is designed for defense! It is resistant to flames, embers, and corrosion, and is able to withstand exposure to the elements without degrading or breaking down.

98% Ember Blockage

Firestorm® Ember Mesh is designed with a small aperture to keep embers out, including debris.
The small aperture size prevents embers from passing through the mesh, which is a major concern for those who live in W.U.I areas.

Ember Mesh Installation

FireStorm® Ember Mesh is extremely versatile. It may be used to protect nearly every opening on a home that could allow for ember penetration, including skirting for decks and ember fencing around your property.

Ember Fencing and Decking

Measure the Perimeter

Measure your perimeter ensuring that you have a proper mounting surface along the entire span of the area to be protected, ensuring that your fastener spacing is no greater than 6”- 8”. It’s recommended to leave a 2” tail on each edge of your Ember Mesh run to ensure ample material to fasten to your framing and supports.

Securing the Bottom Edge

If no mounting surface is present along your span, we recommend digging a small trench approx. 6” deep along the span to be protected. Bend 2” of the bottom edge of our Ember Mesh at 90 degrees. This edge should be facing towards you during the installation. Burry the edge along the span and firmly pack in the dug up material.

Verticals

Our Ember Mesh should be fastened along each upright along your span, as well as along the top edge, ensuring that your fastener spacing does not exceed 6” 8”.

Securing the Top Edge

For decks and framed fencing, fasten this edge with fasteners every 6” – 8”. If no vertical mounting is available, you may follow the same premise as the “bottom edge” and bend 2” of your top edge at 90 degrees facing toward you during installation. Fasten this 90 edge to the underside of your horizontal supports that run along your span.

Retro-fitting Vents

Installing from the front

Measure the existing opening of your vent. Cut our Ember Mesh 2” wider and 2” taller than your existing ventilation opening. This ensures that there is ample room to fasten our mesh to your siding leaving no gaps.

Installing from the back

If you have access to the back side of your existing vent, you can follow the same steps as above, provided that you have a consistent mounting surface on the back side of your existing vent, such as its framing.
