Section 403.4.2 — Prescriptive Requirements
PRESCRIPTIVE REQUIREMENT
“Ventilation openings for enclosed attics, enclosed rafter spaces, and underfloor spaces shall be covered with noncombustible corrosion-resistant mesh with openings not to exceed ⅛-inch.”
HOW RIDGEARMOR ALIGNS
RidgeArmor is manufactured from noncombustible, corrosion-resistant Type 304 stainless-steel mesh with 1/8-inch openings. When installed continuously over an attic ridge opening, RidgeArmor matches the prescriptive material and maximum-opening criteria of §403.4.2.
Project applicability depends on the governing wildfire-hazard designation, locally adopted provisions and any local amendments.
