We need some advice. Our builder plans on placing vinyl siding directly over the OSB board, without using any type of Vapor Barrier. We live in a damp cold climate in the winter, and this situation makes us feel uncomforatble. I have been doing research and come the the conclusion that Tyvek is the best material to be used. Our builder is willing to put a Vapor Barrier at an additional cost, which ok with us, but they want to use a product called Amowrap. I want to know if anyone can give us some advice, and/or insight concerning our current situation.

Ooo. That's scary. I would consider another contractor quite frankly. While no expert by any means, my father in-law is. In fact, he is adding a 2,000 sq.ft. second story to our home. Apparently, the name of the game is not so much vapor barrior as is 'air movement'. House wrap prevents air from moving from inside, to the outside, and vice versa. One of the benefits in the process is that of moisture control. That being said, if a house is too tightly sealed, you can have moisture actually trapped inside where you don't want it. Fortunately, most windows/doors are where the majority of 'leaks' occur (by default), so usually that's not a problem.

My advice is that you do definately want to use house wrap (brand is probably not the end all) to control your air movement. We ended up using Tyvek since that's what Home Depot had, but would have used anything else. The key is to make sure your contractor puts it on in one piece around the entire house as he's able. Then the windows/doors are cut out later. A special tape is used to seal ALL of the seams, tears, etc.

Good Luck!

P.S. Again, no expert. Just passing on what I've learned.

Hey Coairman,Daves advice is all correct. I am not an expert either but I have had two houses built.I had to chime in because I can't understand why a builder in this day and age would not include a house wrap in your type of climate.If your contract does not state that a housewrap is included then you will have to pay extra for it. In my opinion it will be well worth it.

House wrap, such as Tvyek, is not a vapor barrier. It is waterproof but is specially designed to allow water vapor to pass thru. You do not want water vapor trapped in your walls. The 'wrap' seals the various air leaks and provides additional protection from water should it get behind your siding. Would not build a home without it.

Thanks you all for your advise. Now the builder claims its too late, as yesterday they hung all the windows, and should have nailed in the OSB board for the roof today. They claim that for the Amowrap to work effectively, they would have to take the windows out. They also claim that the "Wolverine" brand vinyl siding to be used is sufficient protection against moisture, and air leaks. They claim that they only use the material on brick or stone only. They said that they haven't had any problems with their other homes, and they have about 7 developements of single family homes in the greater Akron, Ohio area. I spoke with a neighbor, and she assured me that they have had no problems without any housewrap installed. Does anyone know of any vinyl sided homes not housewraped, without any air movement problems? Would throughly caulking all joints and seams be effective? I would appreciate any more advise or insight.
