Furring Strips vs. Plastic Mesh for Rainscreens
For my addition project (porch-to-room conversion), I am using ZIP R6 sheathing. I am also going to have a rainscreen. I agreed with the contractor to have furring strips applied along the studs behind the sheathing. We are going to go for 1/2″ strips (rather than 3/4″), as thickening the exterior too much is not an option: on the sides of the new room, the roof does not have overhangs, so, we have to be careful that the siding stays well under the roofline, that is, the drip edge. For that reason, to the extent possible, we are building towards the interior, to the point that, at the lateral rafters––in a lean-to roof––I suggested using a strip of regular ZIP sheathing, with the ZIP R6 starting right under the rafter’s line, so that the 1″ foam part of the ZIP R6 is towards the interior, and the walls do not have to protrude for that one inch towards the outside. That way, the use of ZIP R6 does not thicken the lateral walls beyond the current state. What WILL thicken the walls outward, though, is the rainscreen. Hence the question: Should I consider NOT installing furring strips and, instead, have some premade rainscreen, made of mesh, to be applied? Is that going to be thinner? And is the application of that over the ZIP sheathing a good idea, or will it require all sorts of stapling into the sheathing, which I would prefer to avoid? Also, as the furring strips are already part of the contract, if there is no real advantage (if not drawbacks) to switching to a pre-made rainscreen, I’d prefer to stay with what agreed.
Any thoughts or recommentations on this? Thanks!
