Question of the Day - #101 Wind wash barriers

Postby RDavidson » Tue Dec 09, 2014 5:11 pm

In the current residential code there is a wind wash barrier required between roof framing members above the top plate. Can anyone point out if there is a similar requirement in the proposed residential energy code or has it been eliminated?

Update, update, update! There is a training aid located at http://www.dli.mn.gov/construction/pdf/ ... n/res2.pdf. Slide 39 contains an illustration of air permeable insulation in vented attics. It show a “soffit baffle” and an “eave baffle”. It references R402.2.3 which reads:

R402.2.3 Eave baffle. For air permeable insulations in vented attics, a baffle shall be installed adjacent to soffit and eave vents. Baffles shall maintain an opening equal or greater than the size of the vent. The baffle shall extend over the top of the attic insulation. The baffle shall be permitted to be of any solid material.

Please look at the illustration. Does it appear that the eave baffle identified in R402.2.3 is consistent with the illustration? If the opinion is that R402.2.3 is met by what is shown in the illustration, then where is the requirement for what the illustration identifies as a “soffit baffle”?
