The intent of this document is to provide guidance on the installation of Owens Corning
®
FOAMULAR
®
Insulation in residential
and light frame commercial construction. This document, the reference documents cited herein and any/all information found
on product packaging, literature, and videos collectively constitute the “manufacturer’s installation instructions” referenced in
the ICC family of model codes – specifically the Intl. Energy Conservation Code (IECC), Intl. Residential Code (IRC) and Intl.
Building Code (IBC).
General Guidelines
Optimum performance of Owens Corning
®
FOAMULAR
®
Insulation products is dependent on 1) selection of the correct
product for the assembly or application into/on which it is to be placed and 2) following these installation instructions. General
guidelines which apply to both selection and installation include:
• The framed assembly or masonry surface onto which the Insulation is to be applied must be flat. FOAMULAR
®
Insulation
is a rigid product and not intended for uneven surfaces. Any deformation of the application surface can result in a
weakening of the attachment points and/or cracking of the insulation.
• There should be no voids or gaps in the insulation itself, around any objects that penetrate the insulation or at the
interface of the insulation and framing members.
• FOAMULAR
®
Insulation is not structural. Structural sheathing or code compliant bracing must be used when applying to
wood or metal framing.
