In the video below, we discuss fire resiliency strategies for residential design and construction that have a proven record of mitigating fire risk. He highlights the importance of preventing fire from entering homes by using specific construction techniques and materials, while also advocating for proper landscaping and maintenance practices to create defensible zones.
Prevent fire entry through ventilation
Openings such as eave and crawlspace vents provide an entry point for drifting embers during a fire. Instead of open vents, baffled vents should be used to block embers from entering crawl spaces and attics, which are common points of vulnerability.
Choose fire-resistant roof materials
Various roof materials are suitable for fire-resilient designs. Metal roofs are recommended for pitched designs, while PVC roofing is suggested for flat roofs due to their self-extinguishing properties when the flame is removed.
Use non-combustible exterior wall materials
Stucco and 5/8 gypsum board provide excellent fire resistance for exterior walls. This combination offers a one-hour fire-resistance rating, allowing occupants ample time to escape in the event of a fire.
Select appropriate window materials
The video highlights the risks associated with glass windows in fires. Tempered and laminated glass are recommended for their impact resistance and higher breaking points, while fireproof glass is noted as impractical for typical home construction due to its cost.
Landscaping for fire safety
Culver suggests creating a defensible zone around homes by using non-combustible plants and maintaining a debris-free area to reduce the risk of fire spreading to structures.
