NuSku Fireblocker shiplap wall siding is listed as specified fingerjoint redwood profiles installed over a qualifying backing.
Start a profile comparison with 8140-2064:0102, which requires wood without holes or knots. The nominal board must be at least 1 inch thick and at least 6 inches wide. OSFM also specifies a backing of plywood, gypsum or oriented strand board no thinner than 7/16 inch. Meeting the board dimensions alone leaves that supporting layer unresolved.
Pattern #770, for example, is specified at 1 by 6 inches in the CRA #17 schedule. Match that complete designation when ordering; the schedule also includes other shiplap patterns. A dimension without its pattern number leaves the profile choice unconfirmed.
Before ordering, have the supplier identify the matching shiplap pattern in GOVmotus and the backing intended for the wall. Read the manufacturer's product data sheets and installation instructions referenced in the handbook alongside that selection. A quote for Fireblocker redwood becomes more useful when it also names the shiplap profile and its supporting material.
