Re: Price Per Square For Roofing For New Construction. Roofing and plumbing are the 2 areas I typically under-guess on the remodels I take on. Roofing is always a concern from a quality and safety perspective of the sub (i.e. they need to have liability & work comp insurance).
Some newer fire blankets like the Titan21 are made from 100 percent cotton and treated with a nontoxic and biodegradable fire inhibitor instead of potentially harmful flame retardants.
Tent fabric may be made of many materials including cotton , nylon, felt and polyester. Cotton absorbs water, so it can become very heavy when wet, but the associated swelling tends to block any minute holes so that wet cotton is more waterproof than dry cotton.
