Questions & Answers

Q:Should I use this for faced insulation or should I use the 1/4" leg ?

Answer This Question

A:  ¼" should probably be fine, but if there is any pressure on the edges of your insulation, the extra depth of the ⅜" will help keep it from pulling out.

    A:  Hello, Thanks for your question. Either size should work for this application. We have a resource on our website, The Skinny on Staples, which recommends buying the size you think you need PLUS one size smaller. You can find our staple guide here: http://bit.ly/2NuDT2E.

      ThinHaus uses a lot of staples to hold the Tyvek and other sheathing materials in place. These are the best. They don't jam and they stay put. What more could we ask of them?
