  • Log Gap Caps increase energy efficiency.
  • Log Gap Caps are designed to work with most 6″-11″ diameter logs. The pre-cut Log Gap Cap’s uniform shape fits most log profiles, reducing air infiltration where round logs meet window and door trim. Please note that there are many log profiles available. These are fit guidelines, not absolutes. Tails may need to be trimmed to fit for the smaller log profiles.
  • To use with log SIDING applications, please refer to Log Gap Caps for Log Siding.
  • Log Gap Caps are constructed of material resistant to mold, rot, bacteria, and will not absorb moisture.
  • Engineered from ¾ inch closed cell flexible foam, a Log Gap Cap compresses and remains in place with little caulking required.
  • Seal over Log Gap Caps with Energy Seal Caulk to virtually stop any water or air infiltration, if desired.
