Trap Rod

Log Home Backer Rod and Trap Rod are great for filling the gaps between your log home before applying chinking and other sealing products.  We developed an inexpensive, yet effective "backing", commonly referred to as log home "Backer Rod".  Backer Rod is an extruded, chemically inert, closed cell polyethylene "rope" designed to effectively fill in the gaps between logs prior to the application of Perma-Chink or Energy Seal.

Backer Rod is flexible and compressible; it conforms to the irregularities in the log surface.  It's primary function is recognized as a median between the log gap and the chinking.  Select the proper Backer Rod that fits flush with the logs.

For example, 1/2” backer rod should be used if your finished chinking application it to be approximately 1" wide (for a 6" thick round log). Place the rod in the joint.  Be sure the edges are flush with the log surface.

Trap Rod fills in the gaps on all around log homes where an elastomeric chinking is used.  Trap Rod reduces the amount of Perma-Chink needed to effectively seal the gaps between logs.  Perma-Chink will not adhere to the Trap Rod, only to the logs.

Normal use of Trap Rod (also referred to as Grip Strip) requires minimal adhesives and /or stapling to keep the rod in place.

Snugly fit the Trap Rod into the gap with the narrow side in.  When spacing permits, apply Trap Rod around jams or joints of windows, doors and soffits.

Before you install Trap Rod or Backer Rod make sure gap is free of moisture and foreign material.  Directly place it into the gap using a blunt tool, face roller or the tips of your fingers.

Apply Perma-Chink over Trap Rod or Backer Rod according to manufacturer's instructions.

Grip Strip is a closed-cell product. Under normal use, it will not cause outgassing.  It's unique design provides an excellent fit and surface within the chink joint. This results in a savings in material used.
