    • Strength
Extremely durable product and went on easy and the anti slip worked very well. Very happy with this product and much better than tar paper especially if you want it to last awhile

    • Resilient material, withstands hard soled boots, traction perfect
I've always used tar infused paper up to using this product. This Tyvek 120 provides much less weight to handle on the roof, making going up the ladder and rolling out a breeze. The printed pattern leaves no guessing as to what nail pattern to use. Didn't slip once walking on the laid out product. Provided great traction between the sheathing and backside, between the top surface and footwear. Stayed cool to the touch in bright sunlight on a warm day, leaves no residue on clothes that comes in contact while installing. ... show more

    • Not as advertised.
I only have to shingle part of my house so one roll should have been plenty, so when I came up short I measured every bit I had installed. THIS ROLL IS ONLY 120 FEET LONG! I gave it 3 stars because it seems like good stuff, but I feel cheated. I should have bought it at Home Depot. They apparently sent me the wrong size, not what I ordered. After checking, they gave me a rebate. This is good stuff, and I'd have given it 5 stars if I'd had enough for the job. ... show more

    • Underlayment
We used this to put on our barn walls. They had gaps in them as the barn is really old. It does well to keep the wind and cold out along with rain. It works great for our ducks and chickens.
