Hydro Gap over existing T1-11
I previously posted a question re: installing fiber cement siding over existing T1-11 plywood sheathing/ siding of our house. Since then, I’ve received 3 proposals, and all of them recommend that I use Hydro Gap as WRB over the T1-11 as opposed to a standard rainscreen, since using a standard rain screen would be costly to install (plus our existing windows would have to be moved forward to be level with the new siding).
Has anyone have any experience with Hydro Gap and its performance/ longevity? Any downsides or concerns over this product? We are in the greater Seattle area (Zone 4 Marine), and our house does get a fair amount of rain, and we don’t have big roof overhang protecting our walls.
