Poly Shield® Fan-Fold Wall

alt : Cellofoam-Poly-Shield-Fan-Fold-Wall.pdf

Rapidly Installed, Premium Wall Insulation

Cellofoam Poly Shield® Fan-Fold is a wall insulation and underlayment that significantly reduces application labor costs while adding R-value to your exterior walls. Cut in 24" panels along its 4' x 50' expanse, the insulation is easily transported accordion style and then rapidly unfolded flat and attached. Poly Shield Fan-Fold is typically used on exterior walls as an insulative backer board for siding, but may also be used for other applications such as insulating interior or basement walls. 

Poly Shield Fan-Fold is made of premium expanded polystyrene (EPS) rigid insulation that meets or exceeds the requirements of ASTM C578, Standard Specification for Rigid, Cellular Polystyrene Thermal Insulation. The core EPS is composed of closed cells with excellent dimensional stability, compressive strength, and water resistance. Poly Shield FanFold is faced with tough polymeric laminates on both sides for added strength and durability in storing, handling, and installation. Several different poly facer options are provided to meet project needs. These include printed polypropylene and polyester facers, as well as a metalized, reflective polypropylene. Properly installed with a dead air space, the reflective facer can provide a significant Rvalue boost to Poly Shield Fan-Fold’s thermal performance (see table). Poly Shield FanFold is bundled accordion style, with each bundle covering 200 ft2 or two squares.


Labor & Material Savings: Covering 200 ftin a light weight bundle, Poly Shield FanFold can be installed far quicker than competing 4 x 8 ft insulation or backer boards.

Code Approvals: Underwriters Laboratory Listed, UL ER7260, for interior and exterior walls (as well as for low slope mechanically attached or ballasted roof systems - see related fan-fold roofing flier). Please consult local building codes and membrane manufacturers for system requirements.

Stable R-value: The R-value of EPS is permanent because the only gas in EPS is air. Unlike Polyiso or XPS whose blowing agents outgas and therefore lose Rvalue, EPS R-values do not degrade over decades of use.

Moisture Resistant: Cellofoam EPS is quick drying and does not readily absorb moisture from the air. Its closedcell structure reduces the absorption migration of moisture, and the facers surfaces are nearly impervious to moisture. Not a vapor barrier.

Premium Quality: Meets or exceeds ASTM C578 specs, with excellent dimensional stability & compressive strength.
Environmentally Friendly: Cellofoam EPS contains no formaldehyde or ozone-depleting CFCs or HCFCs. Its EPS core is 100% recyclable and may contain recycled material.

Manufactured to your Needs: Cellofoam Poly Shield Fan-Fold is available in 2 square bundles of 4 x 50 ft, in thicknesses of 1/4”, 3/8", 1/2”, and 3/4” and ASTM C578 nominal densities of 1.0, 1.25, and 1.5 lb/ft3.
