Installing Hardie panel vertical siding over 2.5″ EPS
I have come across the opportunity to purchase 2.5″ Type 1 EPS insulation for very cheap per sq ft and would like to apply it along with new Hardie Panel vertical siding.
I’ve researched about attaching horizontal furring over the insulation but have come to the conclusion that there are no fasteners available that recommended installing furring over Type 1 EPS. The only other solution I see is attaching horizontal furring to the studs in behind the osb sheathing and fitting foam tight in between.
Does anyone know of any other solutions to this scenario? And if not, how would you recommend proper air sealing of this arrangement, I was planning on wrapping over insulation with housewrap.
