While I am not a physicist, it technically depends on the size of the guy and how many beers. Assuming he's Canadian, the concept, in general, is fraught with peril.
epwh - GWB is a classic, proven solution and a perfect fit in some cases. However, most assemblies are complex and hanging GWB, especially multiple layers, can be complex and expensive. Then there are the black mold issues in some environments as well as the risk of impact damage. This instant...
You make an important point - your supplier needs to have ULc S-101. Canada is very persnickety about that - and not just UL, ULc. I think it's just another way to squeeze more money out of manufacturers, but that's off topic for our purposes.
Just ask what the price is. Is it in the $4/sq. ft. range? Do they have testing on steel? How thin is it? How much is needed for your steel type (W10x49 for example). Does it need specialized labor or equipment? Can it be top coated? If you get the right answers to those, you have your...
My pleasure. However, I may have miscommunicated...the new direction in intumescent is NOT expensive - you should be able to find things for less than $4/sq. ft. for materials. Also, depending on the W/D of the steel you have, your coating thickness should be less than 2mm or 70 mils counting...
Much of the commentary here seems to discuss old standards in intumescent technology. I know that products exist that are not so vulnerable to humidity, they are very thin, can be top coated, are lightweight and have very long latency. All of this is quite different from the products that have...
