Dupont’s Tyvek Protec 120 Underlayment

There are new ways to improve your roof and one of the ways is to look for a synthetic underlayment product from Dupont. The Tyvek Protec 120 is a perfect underlayment to go on top of the roofing deck. Underlayment serves several purposes and moisture is one big important purpose. A solid and water resistant underlayment makes for a good base on which to install the top layer of shingles, and it also serves as a shield for any heat that radiates up from the attic. Heat chrome from both sides of the shingles will eventually break down the life of shingles.


A strong underlayment also serves as a backup if strong winds lift and blow away shingles during a strong storm. The underlayment will offer some protection until the roof is repaired.


One of the best roofing underlayment is Tyvek Protec 120 and the great thing about this underlayment is that it works for many kinds of roofing such as cedar shingles and metal roofing as well as asphalt shingles. The Tyvek weatherproof underlayment is a perfect underlayment for Wisconsin weather events such as high winds, hail, and heavy wet snow.

The other draw to this Protec 120 is the textured finish when unrolled making it easy to walk on.  The Tyvek Protec 120 is also lightweight making it easy to hand carry to the roof.


“Built of four bonded layers, Tyvek Protec 120 (appx. $121) delivers the adherence, durability, moisture protection, and foot grip needed to ensure a safe completion and a long-lasting finished product. This particular type is excellent for 2:12 slopes or steeper.”


Although Dupont makes exceptional roofing products the drawback to the Tyvek Protec 120 is that it only has a 3 month UV resistance. Other synthetic underlayment products can last up to one year. This is only an issue if the rood sits unfinished for months. Hopefully with all the shipping and supply line delays this product will not be affected as it’s made in the USA.


When roofing you home there are many options for underlayment but you should consider synthetic underlayment like Dupont’s Tyvek Protec 120 as a sound choice for your roof.
