Facade: Wall assembly help needed
Hello. I have an attached wood frame row house in Brooklyn, NY on a 16′ wide lot about to undergo a comprehensive renovation. Our plan is to use 1/2 x 4″ primed and painted beveled cedar siding as the front siding material. Current proposed wall assembly is (exterior to interior) :
1/2 x 4″ WRC Bevel siding
Benjamin Obdyke Homeslicker (rainscreen)
Rockwool on exterior for CI
Solitex Mento 1000 (WRB)
5/8″ plywood sheathing
Rockwool batt between the studs
Aqualock primer + regal select paint
I definitely want some type of exterior insulation and want to use WRC as my siding material. But how does the siding attach to the insulation layer ( weather Rockwool or exterior rigid foam). I originally wanted to use furring strips on the rockwool to attach the siding but i dont think i will have enough depth on the front exterior and i dont want my facade to stand proud of my neighbors. Thats why i thought of using the Homeslicker for some venting behind the wood siding as a space saver that still achieves similar objectives in terms of drying.
I was also considering using the ZipR sheathing since the insulation layer is behind the sheathing and i would be use the Homeslicker and directly attach the siding to the OSB. Would that work? I’ve heard very mixed things about ZipR which is why i’ve gravitated away from considering it.
Also, on the interior, could i benefit from using a “smart” vapor membrane like Intello or something similar?
The front facade is about 450 sq ft – so its not a huge amount of space so cost considerations are secondary to building a smart assembly with the highest quality materials.
Would really appreciate any comments from the community. Thank you, Armen
