Wood siding is the.
Moisture barrier for wood siding.
Just a couple of weeks ago we were being told that there is now evidence that during the air conditioning mode a house is subject to moisture problems on the outside face of the interior vapor barrier especially if the house has wood siding.
If this happens and the water can t evaporate rapidly back into a gas wood rot mold and mildew become a reality.
You can keep leaks from making their way further into the wall with a moisture barrier behind the siding.
Although your siding is your home s first defense against wind many types have small gaps and cracks at the joints where siding panels line up.
Effective moisture proofing begins before the siding is even installed.
Always refer to current local code recommendations when deciding if and how to install vapor barriers.
For example the recommended vapor barrier in a home or office in a humid southern climate built with brick varies greatly from creating a vapor barrier in a cold climate in a home built with wood siding.
And that leads to air infiltration and seepage the kinds of things that drive up energy costs.
