No House Wrap Under Siding

This explains why the house does not retain heat.

No house wrap under siding.

House wrap is a common type of insulation on new homes. Siding manufacturers may recommend specific types of wrb to use with their products. Wood fiber cement vinyl brick stucco and others. In the end the decision to install house wrap under your siding is a personal one that you should make after discussing it with your contractor.

Vinyl siding is one of if not the most popular exterior cladding for residential homes. Each and every one of them had hardie installed improperly and all had to be replaced. The material is designed to keep out moisture and reduce drafts while simultaneously allowing the walls to breath. So your builder is not offbase on that.

The only time you don t want a house wrap is if this is a temporary structure or completely weather proof on its own. As well since the wrap isn t tucked into and over the sills it s not much use as an air barrier. It seems that we have two options. However if you re interested a residing project offers the perfect time to examine your home s weather barrier and exterior insulation and improve it if need be.

The second would be to blow insulation into the walls. During a recent repair to our siding we found that the house had no building wrap tyvek under the siding. The wrap comes in rolls and is stapled directly onto the wall sheathing. House wrap is intended to be installed over the sheathing and behind the siding no matter what siding you are using.

It s often cheaper to install a house wrap than weather proof the exterior of your shed so this is usually the best option for people that want a long lasting shed for their man cave or otherwise. Adding housewrap at this point when the windows and doors are in may cause water problems around them. Though i ve never heard of a local code official denying approval of a housewrap but it is within his authority. There is no logical reason not to have house wrap under vinyl siding and many authorities strongly agree that it should be viewed as mandatory even if your local building codes don t necessarily require it.

I wont name names but there was a new development of a few hundred town homes put up near me a few years ago.
