Walls using foam sheathing can meet all structural code requirements with simple specification and planning.
Tools & Education
This guide provides designers, code officials and builders a basic understanding of how to apply the IRC bracing provisions for code-compliant dwellings and how the IRC bracing provisions can be used to create maximum value in a diverse housing market.
Research report intended to supplement the window manufacturer's installation instructions, where installation over foam sheathing is not specifically addressed. Also suitable as an alternative method of installation based on commonly accepted field practice. Available as a sealed code compliance report.
Requirements for installation of vinyl siding over foam sheathing in thicknesses up to 4" when used as thermal insulation in exterior walls. Available as a sealed code compliance report.
