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.
Two single strands of fiber optic cable attached at the center. Surrounded by a 900 um buffer then a layer of Kevlar and finally the outer jacket. Available in 2mm or 3mm. Plenum or Riser Jacket. Plenum is stronger and made to chare in fire versus riser is made to melt in fire.
