<VV> Foam rods for Headers

[BBRT]

Any comments re this stuff? Insert wire of some sort to hold shape, slice on inside of bend as required to bend to required radius.

Anyone used any version of this? How stiff is it? Looks pretty flexible.

            Product Description

            Basic Use: ITP Standard Backer Rod is an ideal nonabsorbent compressible backup material. It is inserted into a joint to control sealant depth to create a backstop to:
            * Allow proper sealant tooling
            * Allow proper sealant wetting of the joint surfaces
            * Yield a proper bond breaker between the Backer Rod and sealant
            * Function as a temporary seal. 
            Compatibility: ITP Standard Backer Rod is compatible with butyl, polysulfide, acrylic polyurethane, silicone and most other cold applied sealant compositions.
            Specific Use: Commonly used in glazing installations, windows and door applications, expansion joints, curtain wall joints, partitions, log constructions, pavement joints, repairs, precast units and copings.
            Composition and Materials: ITP Standard Backer Rod is an extruded round, closed cell, low density polyethylene foam material with a skin-like outer texture. It is highly flexible and compressible for easy installation.  Available in stock grey and a wide variety of diameters.
