Provides procedures for the installation of urea-formaldehyde foam insulation. It includes a requirement for the installer to ensure that formaldehyde concentrations in building air do not exceed limits acceptable to relevant health authorities.

This Standard sets out recommended practice for the installation of urea-formaldehyde (UF) foam, which is manufactured and dispensed on site into the cavities of suitably constructed walls, ceilings and floors for thermal insulation purposes. This Standard defines constructions to which this application is limited.
