Tyvek

Postby rainjer » Wed Apr 12, 2006 4:40 pm

Has anyone tried using Tyvek as a moisture barrier under their skin/roof?

It seem it would be good insurance to help prevent leaks. It is breathable & water resistant.
More info:

I was thinking of using it between the roof spars & the skin. It is light weight & I can get it for free.

Any thoughts.

Do a "search" on it and I think you'll find it's been discussed before.

All I know about it is it makes a great kite.
I know its the photographer, and not the camera. I'll keep shooting with a Pentax. Just in case.

    Rainjer,
    If your skin (wood, aluminum, ect.) and fasteners are sealed, I see no advantage in creating a barrier directly under the exterior. An interior vapor barrier or insulation choice would be more important in cold weather to protect the inner framing and insulation from moisture damage from within.

rainjer,

One thought came to mind while I was out running errands this afternoon. If you put a vapor barrier (like Tyvac) down under your teardrop skin, what surface will you have to glue your skin to????? :thinking:

FYI: Tyvec is not a vapour barrier, it's a water and air barrier. Water vapour goes through it like a hot knife through butter.
Commandant Louis Joseph Lahure has a singular distinction in military history - he defeated a navy on horseback. Occupying Holland in January 1795, the French continental army learned that the mighty Dutch navy had been frozen into the ice around Texel Island. So Lahure and 128 men simply rode up to it and demanded surrender. No shots were fired.

That's why I didn't put any vapor barrier other than my foil-backed foam insulation. I wanted good wood to wood contact between the skins and frame. I put Tyvek on my previous house in Maryland when I replaced the old composite siding with vinyl siding.

Sometimes I pretend to be normal. But, that gets boring...so I go back to being me.

You are quite correct...........my error. But the net result of him using Tyvek would be that he'd lose the neccesary requirement of good wood to wood contact for the gluing process.
