Partial House Wrap
 
I would like some advice regarding the installation of Tyvek. I'm building in Northeast Ohio. The house will have vinyl siding. My contractor believes that the gable ends of the house should not be covered with Tyvek since those portions of those walls are not insulated. Every other house under construction in this area is completely wrapped, including gable ends. Any thoughts??? Thanks.

I see many houses that don't put vapor barrier on gable ends. My thought when using vinyl tyvek is it protects the framing from the elements better than the vinyl siding does...

Tyvek as I understand it is not a vapour barrier in the same sense as what you would install on the warm side of your walls (poly) it sheds water on the exterior but will also allow water vapour that accumulates in the wall to evaporate to the exterior. Kind of like Gortex rain suits. I believe that you couldn't go wrong by doing the gable ends, just a little more expense thats all.

When my house was vinyl sided about a year ago. All clapboards removed and house wrap installed including over the cable ends. The house wrap they used is listed below. I think because thats what our lumber company in town carried.

Why are the gable ends of the house not insulated? Unless you're talking about only the parts adjacent to the attic space, they should be insulated. And if you're only going to leave the wrap off of those 2 small areas, you won't be saving enough to worry about whether it should be done or not. It won't hurt to wrap it even if it's not insulated.

I see this often. I think it's the contractor nickel and diming the customer...
