My son is building a tiny house made of SIP panels. The built structure has been treated inside and out with "Enviro Dry". The current plan is to install cedar shiplap siding using stainless ring shank siding nails to avoid splitting and color issues. Any tips on nailing into SIPs, spacing, nail lengths? Do we need strapping boards to allow air to flow between siding and SIP panel. I was told we did not need Tyvek wrap due to the "Enviro Dry" Sound correct? Any other words of wisdom are welcomed. Tks,

Hi gpolkin, just to be sure, you're talking about an OSB type SIP is that correct? And what is your climate/region?
