Chapter 14 of the International Building Code addresses exterior walls and facades. Exterior walls must be constructed with fire-resistance ratings determined by the construction type and occupancy. Noncombustible construction requires limited fire-resistance for exterior walls, while combustible construction in Type V buildings may require 1-hour fire-resistance. Wall assemblies must have fire-resistance tested per ASTM E119 or equivalent, accounting for exposure on both sides. Water resistance is critical to prevent moisture infiltration. Exterior walls must have water-resistive barriers (house wrap or similar) and appropriate flashing at penetrations. Drainage must be provided to shed water away from building. EIFS (Exterior Insulation and Finish System) materials include a layer of insulation covered with a synthetic finish. EIFS must include a moisture barrier and proper detailing to prevent water intrusion. Metal cladding and roof panels must be designed to resist expected wind loads. Wind loads vary by location per ASCE 7 standard, with coastal areas typically experiencing higher wind speeds. Building height, exposure category, and importance factor are considered in wind load determination. Masonry veneer (brick or stone) on wood frame buildings must be supported on steel angle or ledger and properly flashed. Masonry ties connect veneer to backup wall and are spaced 16-24 inches apart. Vinyl siding is permitted in most climates with appropriate nailing and gap provisions. Fiber cement board siding has improved durability compared to vinyl. Window and door openings in exterior walls require proper flashing and trimming to prevent water leakage.
