Christmas tree fasteners are used to permanently attach plastic vapor barrier to the foundation walls of the crawl space. These plastic retainer clips got their start in the automotive industry and was quickly adopted by crawl space companies and DIYers to make crawl space vapor barrier installation simple and effective.

We recommend using our 2" Butyl Tape in conjunction with the Christmas tree fasteners to secure the vapor barrier to the foundation wall.

    Christmas Tree Fasteners worked great with Foam board!

    Posted by Jon on Dec 4th 2021

    Used Christmas tree fasteners in concrete block for the piers, and in the top of the 2" foam boards that were tapcon-ed to the wall. This seemed better than anchoring the fasteners to the concrete block, as near the top of the foam board, the plastic will pull at a 45 deg angle, whereas in the top of the foam board, the pull is at a direct perpendicular angle. Plus, you can simply press the Christmas Tree Fasteners in by hand through the sheet plastic into the foam board, and they are not coming out without a struggle!

    I installed mine through the plastic and butyl tape into 2”foam board and they hold tremendously!

    Worked perfectly

    I was worried these wouldn't work in my old crawlspace walls ... no need to worry. They are holding perfectly in less-than-ideal concrete! Having small hands, I used a rubber mallet to tap them in (GENTLY!!).

    Great

    Great and easy to use. I also made a small flap at the ends and was able to double the holding power to the vaper barrier. Only four stars because i didn't see a fastener available that could hold my foam board. ( not long enough)
