## Description

Tyvek Protec 160 Roof Underlayment - 4' x 250' - 1 Roll - desertcart.com

Review: Class A rating! - I bought for below a standing seam metal roof. In fire country, I like metal roofs. But to be as FR as possible, a good class A underlayment is desirable. Ideally for metal roofs, they don't like cap nails, they prefer glue down. But all the glue downs don't seem to be Class A. (probably the adhesive is flammable?) What I've done is to use this Tyvek membrane, then use stainless cap nails, (as the normal nail head might rust the underside of the metal). A bit more pain to nail stainless if you normally use a magnetic head hammer for cap nails, but, worth it. This produce is NICE to walk on. You feel pretty safe.
Review: Shrinks - When you install this stuff it fades fast and seems to shrink in the sun. Don't worry about getting it flat because it shrinks and pulls flat in the sun. Have enough fasteners to keep it in place, it will show stretching at the edge fasteners. If your roof is under a 4 in 12 pitch it says in directions to apply 2 layers with a stagger in the horizontal seam of around 13".
