Lumber yard sells barricade for house wrap. Is it good to use or something else on new construction? Thanks guys

All house wraps have to meet a certain permeability rating so the particular brand is not too important. When we were a Platinum Certified Energy Star Builder all we had to show was that we properly wrapped the house which included properly overlapping the seams and taping the joints.

The industry leader is TYVEK brand if you’re interested in the best as it is more uniform in its construction but as I said there’s not much difference between the various brands in terms of actual performance.

I used Owens Corning wrap. It’s what Home Depot stocks. I’m happy with it overall. We had an unusual storm a few weeks back. 2.5” in 30ish minutes. Not a drop penetrated. This was prior to foam and stucco, so it was just the house wrap, against the wind and rain. It did fantastic.

There is a new house wrap with an R-value of 6.

That’s been around for a few years and I actually met the guy that invented it but after doing a little research I found that the methodology he used to get his R value did not meet the industry standards. I passed on using it.

There was a law suit about the R-value and they won.
It is hard to find anyone that carries it at the present time.

Most installations are put on wrong. Watch them use a stapler to tack it to the siding and over lapings are not taped. I watched five neighborhood houses get house wrap and only one was put on correctly.

Having an R value seems counter intuitive as house wrap is made to allow air flow but stop water from penetrating.
We resided the house about 10-12 years ago and can't remember which one but it wasn't Tyvek but it was a brand name I recognized.
Assume most do a decent job.

The house wrap is like living in a balloon which keeps out water and air reducing heating and cooling costs. A wrap with an R-value would only further reduce heating and cooling costs.

It is amazing how things have changed. I remember builders using tar paper decades ago.

If you're also using the wrap to prevent air infiltration it needs to be sealed on all sides, including taped to the concrete foundation.

If you want R value then add foam board over the top. In addition to the R value itself it will slow thermal bridging through your studs. If going this route you'd want to use the crinkled wrap made for use under foam boards.

In addition to properly sealing our house, we added 1" of foam to the exterior. It made a tremendous difference this last winter.

No, using it as a barrier from the elements.

It i designed to breath. Not seal the house up tight.

Pretty much all new homes get it here. As long as it does not hurt anything I am good with it.

Does it do much good. Questionable. Might keep rain off of the exterior until the siding goes on

Your house will breathe through it. That’s what it’s designed to do, while moving moisture one way from inside to out. If you don’t seal it all the way wind can move the air behind it, through the gaps in your home.

Air sealing your home, including top plates, saves a lot of energy.
