Re: California burning:


Asphalt shingles catch fire and are hard to put out, much of the applied stucco these days is over large Styrofoam blocks of ornamental detail that melt and erupt in a fire as the stucco fails.

These fires if you look at the maps started in the foothill canyons, they follow the fuel lines, homes, tightly packed homes with plenty of dry tinder surrounding them as tall grass demarcation landscape features go up like incendiary devices.

Then the point of NOT allowing Nature to perform minor burns, ALL small fires are quenched before can do 'Damage' where all they were doing was removing excess tinder that is allowed to remain, IE the 'Natural Landscape' so many are enamored of living with.

Oh.
So are you saying it is a fair point ?




Probably.
I have never seen this pink fire proofing on any other show. However, this is also the only Canadian show I have seen.
So I can't be sure either.

Agreed.
I always go metal roof in the country.
Asphalt shingles are not only flammable, but heavy, backup water, don't last, and are labor intensive.
Like ceder shakes even less, since they have to "breath", so can't have solid underlayment.

Re: California burning:


Metal roofs are usually held up by timber rafters or they are in NZ. So in a fire, the metal roofs buckle and twist and the timber burns.

Do you have metal rafters or timber ones?

The metal covering slows the heat down, so if it is not too long, the timber will do ok.
But it is not that hard to use steel beams of spray on fire proofing.
The last building I put up is all concrete block and steel. But that is for car work and welding. Not well insulated.

Yep - if you've ever watched other home improvement type shows you'll occasionally see materials where the company logo is blocked out - that's usually because the supplier isn't a sponsor and/or didn't donate the materials.

Re: California burning:


Has been noted the communities involved were 'considered' Outside the fire danger zones in the regions where fire danger is prevalent so the fire retardant codes were dismissed if not just ignored for "Cost Savings".

The issue is not fire taking over as much as poor pre-planning for fire dangers.

http://www.latimes.com/local/lanow/la-me-ln-coffey-park-explainer-20171011-story.html

As to metal roof buckling, by the time a steel roof reaches the temperatures to cause buckling the interior of the structure is most often ALREADY on fire. You reach a flash over temperature high enough to cause steels to buckle the wooden structure within has already flashed into full blown fire.

Re: California burning:


The fire danger in CA is well known, on slopes and canyons where wind can be accelerated, when there is dryness, etc.
It is not hard to either not build there or build fireproof.

And the images of green trees behind the burned out buildings, shows there was no reason for the buildings to have gone up.
They simply had been abandoned.
You can easily build a rural storm cellar that can also be safe in any fire.
The only times a storm cellar won't work is with an urban firestorm like Dresden, because then the oxygen is pulled right out like with a vacuum cleaner.

Re: California burning:


Buildings today are full of accelerants by design, glue laminated lumber, OSB which is glued together chucks of wood product pressed into a form, Styrofoam insulation, asphaltic shingles, then all the plastics, vinyl siding, and cellulose fiber compressed wood product furnishings.

Get a fire in one it basically explodes, the heat of which sets the next and the next.

Used to be a standard of 10 minutes to escape a home fire where you live, that has dropped to 2 minutes, no better than living in the age old Mobile Homes.

Re: California burning:


The New Science Fire Safety Journal was interesting.

{...
In the experiments, three modern home configurations were tested against three
“legacy” configurations, defined as having furnishings from the mid-20th century and
building materials from between 1950 and 1970. The tests showed a consistency of
results among the three modern rooms and the three legacy rooms that we examined.
All of the modern rooms transitioned to flashover — flashover occurs when the majority
of exposed surfaces in a space are heated to their autoignition temperature and emit
flammable gases — in less than five minutes, while the fastest legacy room to achieve
flashover did so in just over 29 minutes. In the three sets of experiments, legacyfurnished
rooms took at least 700 percent longer to reach flashover.1
The experiments revealed that the natural materials in the legacy rooms released
energy more slowly than did the fast-burning, synthetic-furnished modern rooms,
which leaves significantly less time for occupants to escape the fire. The experiments
also demonstrate to firefighters that in most cases, the fire has either transitioned to
flashover prior to their arrival or has become ventilation-limited and is waiting for a
ventilation opening to increase its burning rate. This difference has a substantial impact
on occupant and firefighter safety and leads to faster fire propagation, shorter time to
flashover, rapid changes in fire dynamics and shorter escape times.2
