Aluminum wrap used during California wildfires to protect homes, trees – Honolulu, Hawaii

Myers, Calif .: Contractor Martin Dicky said he panicked when a wildfire in Myers, Calif., Near Lake Tahoe began to move towards the wildfire. However, he could do some simple investigations and decided to wrap his wooden house in a protective aluminum cover.

The cover, which can withstand short periods of intense heat, is similar to tin foil, but is modeled after a tent-like shelter used by forest firefighters as a last resort to protect themselves from flames.

Dicky bought a wrapping from Fire That in San Diego for $ 6,000 to cover a 1,400-square-foot villa.

Wrapping dissipates heat from the building and prevents flammable substances from igniting. It also prevents embers in the air from entering vents and other openings.

The sheet, when combined with a fiberglass lining and acrylic adhesive, can withstand heat up to 1,022 degrees Fahrenheit.

This week, the fire brigade wrapped the roots of the world’s largest trees in aluminum in California’s Sequoia National Park, General Sherman Tree, and other Sequoia, museums, and many other buildings.

The US Forest and National Park Services account for 95% of Firezat’s sales, and the company’s founder, Dan Hirning, said the Forest Office will have 600 to 700 buildings, bridges, communications towers, and other structures this year. I said I wrapped it.

Firefighters described wrapping as a “big baked potato” on social media, and Forest Office officials said they had been using wrapping for several years to protect sensitive structures in the western United States.

Firezat’s fireshield rolls are 5 feet wide and 200 feet long, each costing about $ 700, and contractor instillation costs an additional thousands of dollars.

As the Associated Press quoted, “people think we should sell a lot of these things, but not as much as everyone thinks,” Harning said, his individual customers. Most of them are trying to protect “really expensive cabins, really expensive”, he added. Homes and resorts. “

Fumiaki Takahashi, a professor of mechanical engineering at Case Western Reserve University in Ohio, published a 10-year study of protective wraps in the Frontier Journal of Mechanical Engineering in 2019.

The aluminized surface of the wrap blocked up to 92% of convective heat and up to 96% of radiation, he said, and said further research was needed.
