Deck Construction In Fire Areas

Deck Construction In Fire Areas

We build decks in an area where wildfires are a concern. What products or strategies can we use to reduce the risk of fire?

Pvc fireproof decks that overhang a slope can be more vulnerable to ignition because of the increased potential for embers and flames from burning vegetation to reach the deck, particularly when vegetation downslope from the deck isn’t managed and maintained. Effective and inexpensive ways to make a deck less vulnerable to wildfire exposure are to remove combustible materials from under the deck and within 5 feet of the home, and to manage the vegetation on the property leading up to the deck.

Fireproof Technique Technology Reduces Fire

Another wildfire defense technique is to enclose the deck by attaching noncombustible fiber-cement sheathing to the bottom of the deck joists. While this may provide protection from embers and flames, be sure to provide under-deck drainage. Without it, fungal decay may develop in the joists and metal hardware may corrode prematurely—even in dry climates, where wildfires are more common.
