IBSx Roundtable: Behind the Siding—WRB, Drainable WRB, or Rainscreen?
Fine Homebuilding hosts a panel of building pros in a discussion of the various types of high-quality substrates that can be installed under siding to make a wall assembly more durable.

Sometimes, a flat WRB is all that’s required behind the siding, other times a drainable housewrap makes sense, and some projects demand a full rainscreen assembly that can be installed with a manufactured rainscreen material or can be site-built.
In this roundtable, Fine Homebuilding editorial director Brian Pontolilo invites Benjamin Obdyke technical innovation manager Kaylen Handly, building-science expert Khota Ueno, and contractor and former FHB editor Justin Fink to discuss the differences in these approaches and help builders determine what is most appropriate for each project.
