Grip Strip - Trapezoidal Foam Backer

Grip Strip is chemically inert closed-cell polyethylene that is shaped to fit between log courses to form a flat surface for the application of Perma-Chink or Energy Seal. This makes it easier to maintain a consistent thickness of sealant across the seam, reducing the amount of sealant required and improving the sealant’s performance.

  • Provides a firm chinking or caulking surface
  • Shape and texture allow it to be easily installed without using staples, nails or glue
  • Repels water
  • Compatible with all commonly available synthetic chinking
  • Helps prevent blistering of chinking surfaces
  • Provides extra insulation against heat loss

five star P Malkmus in TN (04/27/15) - "I am a professional log home Applicator in TN and this is the perfect product for insulating and caulking in the sides of windows, doors and eaves that have a big gap. I would not want to caulk or chink a house without it!"

five star J Robison in PA (11/17/14) - "I still love your Grip Strip for seams that are 1" or 2" wide and also on round logs but for anything over 2" I have switched over to cutting Styrofoam board."
