Drafty House - adding tyvec to a nine year old vinyl sided house?
 
My husband and I are trying to figure out ways to make our home less drafty, and we have a few issues we need to address. The first one is if it is possible to tyvec wrap our home now, or even feasible, without purchasing new siding. If so, how?

do you mean remove all the old siding and trim add the housewrap and reinstall? Sure anythings possible.Where are the drafts? windows? doors?
along the baseboard?probably be a better idea to attack those areas first

drafty house
 
I wish the drafts came in from the doors and windows. That would be easy. We have a major problem with our fireplace. It is cantilevered outside, is a woodburner with a gas insert, and we finally taped styrofoam over the entire opening so can't use it, but it stopped most of the draftiness. I think the damper handle is broken, and since we're using gas, we don't really need the damper to be open, but don't know how to fix it. Ideas? C
About the Tyvec: could we just do the long walls on the north side of the house to make the job less labor intensive? Would that help?

I was just ready to say yes it could very well help...then I re-read your post and saw that the home is only nine years old. I cant imagine the sidewalls of a home that new being so drafty.
I would first investigate the insulation in walls. Also anywhere the floor cantilevers. I cant count the times I have seen shoddy installers apply soffit material under a cantilever that has not been insulated. That alone can make the interior floor and wall cold and seemingly drafty.

how do you know you dont have tyvek or some other house wrap already?Jer is right cantilevers are not adequately insulated and air sealed alot of times

Tom Struble 02-04-2009 01:59 AM

i would ask that question about your fireplace in the hvac forum

I would install a cap mounted damper. It's certainly DIYable.
I wouldn't feel comfortable venting the gas log to the interior as they do emit carbon monoxide.
Some other areas to look at are the dampers for the range hood to make sure they are functioning properly. Walk around with a stick of incense, you'll quickly see where the problem areas are from the smoke moving around.

drafty house
 
I know we don't have Tyvec, because we had the house built. My husband was afraid Tyvec would keep a house from breathing and possibly add to radon inside, so didn't want it. We have the old style black tar paper, or whatever it is.

Thanks for the suggestion about the damper. I'll be adding it to the honey do list! Also, checking the cantilever. I bet you're right1
