No Homewrap for new home in Minnesota
 
Homewrap Is It Part Of Building Code In Minnesota ? And is it needed? What are the benefits of having it and effects of not having it? The reason I'm asking this is because I am building a new home and my builder is not putting the housewrap.

Minnesota building code specifies a particular brand of house wrap?

Did you even ask the builder? If not, why? If so, what was his reason for not putting it on? Does it say it on your plans?

Has he said he's not putting it on, or has he just not put it on yet? When my new house was being built, they didn't put the housewrap on until the day the siding was installed.

Thanks for the valuable questions. Based on the questions posted here. I have contacted the builder, he now says that they will put on the wrap just before siding time only. Hoping that's the case. We understand that they would do the siding in about 30 days from now. Hoping that's OK time frame to wait and see.

We are concerned that the plywood would damage because of the storms we see here very often here. We are in a community where lot of new houses are being built, and all other builders are putting on the wrap immedialtely after the framing. We are just concerend with the weather in the mean time.

make sure it goes on the right way as far as lapping goes or if the plans say if it should be taped,make sure all penetrations are properly integrated

while installing wrb is not rocket science it does require some attention to detail,siders are sometimes more interested in just the siding when its the wall prep that is really more important for your homes protection

Have you looked on your plans also?

The plans say that a wrap will be there, but does not say when? The builder now is saying the wrap will be installed only a day or two before they put on the siding. Is that OK?

But the other builders are putting on the wrap right away after framing and not waiting until the siding time. We think what others builders are doing is better way. Any suggestions?

Tom Struble 08-08-2010 12:47 PM

some builders like to dryin the building as soon as possible,others wait longer but it really must be there before any mechanicals or insulation is done

I thought the house wrap should be on before any windows go in so the wrap can be tucked behind the window mounting flanges on sides and bottom. If the wrap is going up several days before the siding, are the windows going up in these few days prior to siding, i would think windows installed before siding goes up.

Tom Struble 08-08-2010 01:52 PM

windows in first yes, wrb not necessarily so

Gary in WA 08-08-2010 04:19 PM

The inspections have to follow the correct order, as per B.D. Usually: frame inspection (the windows are already in as the framer installs these); mechanical (HVAC)/ plumbing, electrical, etc.... Some builders schedule frame separate rather than same time as mech/plumb, easier on the inspector for trips made. After frame, you can install wrap to dry-in for electrical sub. Some areas sheath walls and paper/wrap gables only before electrical work.

Be safe, Gary
