EPS Drywall Backer
Expanded Polystyrene (EPS)
Foam-Control® EPS Drywall Backer adds a continuous energy-saving insulation layer for the building interior. Foam-Control® EPS Drywall Backer is a rigid insulation that will not slump or lose R-Value. It is clean, non-itchy and easy to install.
Scored Foam-Control® EPS can be provided for wood stud, metal lath or J-track and Z-channel systems. Other field-installed attachment systems meeting code acceptance, i.e., adhesives, etc., can also be used. Vertical or horizontal attachment of gypsum board or other code-compliant thermal barriers progress quickly.

EPS Drywall Backer Installation Instructions
Foam-Control® EPS Drywall Backer will be installed tightly where shown on drawings. Provide ASTM type, size and thickness as stated in drawings or as part of this specification.
Apply material between field-applied attachment channels or through integral factory furring channels. Use fastening systems compatible with the building substrate and insulation system. Use frequency recommended by fastener manufacturer.
If adhesives are required, use an adhesive that is recommended with EPS and the substrate. With Drywall Backer secured into place, drywall or thermal barrier application may commence.
Foam-Control® EPS Drywall Backer comes in flat sheets or can be scored in multiple width locations for convenient installation and can also be used for exterior applications, provided exterior cladding is applied per code and cladding manufacturer's recommendations are followed.
Protect material during installation or related operations. Foam-Control® EPS must be protected from exposure using a weather-resistive covering.
