Foam Backer Rod Insulator

Fill large gaps in your windows and doors with our Foam Backer Rod.  When the gap may be too large for regular foam tapes, the Foam Backer Rod is a perfect solution to fill cracks, holes and large gaps in your windows and doors.  The product may be used in many areas of the house to fill in large gaps as it will remove drafts, reduce heating and cooling loss, save on energy costs, and improve noise reduction.  Use it with sealant or caulking for a tight seal that will last for many years.
