Backer Rods are used for concrete precast building. Backer rods are inserted between the concrete panels to fill the gap, thus providing a ‘backer’ for the sealant that is applied. These backer rods can be
used around doors, windows, wall joints, as well as foundations.
Backer Rods are recommended in numerous construction applications because it:
– Saving sealant material by filling in most of the gaps
– Providing additional insulation and increasing energy efficiency of a
house
– Blocking drafts, giving additional quality to window installations.

FARMESACO’s Backer Rods In Focus

Our Backer Rods are closed-cell, resilient, polyethylene backer rods used as a backup material for construction joints and applications which require sealants. They perform as a depth control for most known cold-applied sealants. Sealants will not adhere to the Backer Rods and no bond breaker is required.
