Air Infiltration Barrier On Board And Batten Siding

But when it comes to durability engineered wood siding is a smarter buy compared to solid wood siding because it mimics its look but features greater durability and easier maintenance.

Air infiltration barrier on board and batten siding.

I am thinking about using vertical pine board and batten on the exterior of my new house. That would leave an air gap there of 1 5 between the studs and the back of 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. In the 1960 s they took off the battens and put up that ugly tar paper siding over the boards.

Air and moisture barrier such as house wrap or felt paper must be applied between siding and sheathing plywood to avoid water infiltration. We install moisture barriers because we know the siding will leak due to rain storms wind etc if you live in a cold climate in winters i d use a vapor barrier on the batt insulation but don t install plastic sheeting on the walls. The old farmhouse we are redoing originally had board and batten siding cut and milled right here on the property yellow pine. We have had our rainscreen board and batten siding for nearly 10 years and it looks brand new.

Although the insulation may balloon that air barrier outward somewhat into that 1 5 air gap. 10mm air space between the wrb and the panel siding formed by minimum 3 8 inch furring.

The infiltration barrier would be sandwiched between the outside of the studs and the 2 x 4 horizontal nailers. And that leads to air infiltration and seepage the kinds of things that drive up energy costs. The house was built in 1965.
