1American Martin Diky says he panicked recently when a huge wildfire began racing down a hill toward his home in Northern California.
2He did some quick research to learn how how he might protect his $700,000 mountain home near Lake Tahoe.
3He chose to cover his house with a product called fire wrap.
4Fire wrap is made with the soft metal called aluminum.
5The special aluminum covers withstand very high heat for short periods of time.
6Diky bought $6,000 worth of fire wrap from a California-based company called Firezat Inc.
7That was enough to cover his 130-square-meter home on the edge of the small California community of Meyers.
8The fire wrap is very costly, Diky said, "and you'd feel stupid if they stopped the fire before it got close," he added.
9"But I'm really glad we did it."
10Fire wrap is not widely used by homeowners in America.
11Along with the high cost, it is difficult to put in place.
12But the material has saved properties, including small historic houses, or cabins, owned by the U.S. government.
13It can even be used to protect the living.
14This week, firefighters in California's Sequoia National Park covered the base of the world's largest tree with the aluminum.
15The tree, known as The General Sherman, is thousands of years old and stands in the park's Giant Forest area.
16Protective aluminum wrapping can deflect temperatures as high as 550 degrees Celsius.
17Any structure underneath the wrap stays cooler.
18This helps prevent fire-linked explosions.
19It also keeps small, pieces of burning material, or embers, from entering small openings in buildings.
20Firezat's biggest customer is the U.S. government.
21The Forest Service and the National Park Service are responsible for about 95 percent of the company's sales.
22Dan Hirning is Firezat's president.
23He estimates the Forest Service has wrapped 600 to 700 buildings, bridges, other structures and trees on its sites just this year.
24Firefighters on social media have compared the shiny, silver-colored wraps to a "big baked potato."
25One firefighter who helped cover some structures said it felt like he was wrapping Christmas gifts.
26Fumiaki Takahashi is an engineering professor at Ohio's Case Western Reserve University.
27In 2019, he published a report about the effectiveness of wraps used for wildfire protection.
28He said they "demonstrated both remarkable performance and technical limitations."
29The wrapping is most effective if a wildfire moves quickly beyond the structure, he said.
30It is less effective in areas with many houses.
31The wraps "show promise in being effective," he said.
32But additional research is needed to develop more effective and lightweight versions, Takahashi said in an email to The Associated Press.
33He said he would not suggest the products for use by everyone because wrapping correctly is still a complex process.
34But, once a dependable wrapping method is in place, he said, he would call for wider public use.
35Firezat Inc. sells its fire wrap rolls for $700 each.
36They are 1.5 meters wide by 61 meters long.
37Getting a structure wrapped usually costs thousands of dollars for labor.
38Hirning said most individual buyers he has had over the years are looking to protect, in his words, "really expensive homes."
39They include homeowners in Malibu, California, who are asked to sign an agreement that the Forest Service is not responsible for protecting their property in some cases.
40As for sales increasing as a result of recent wildfires, Hirning said that it is an extremely seasonable business.
41Once it starts raining and snowing, he says he often does not sell anything for nine straight months.
42That could change, however, as climate change leads to more extreme and destructive weather and a longer wildfire season.
