Top 5 questions asked by customers purchasing crawlspace liners.
Q: How do I know what thickness to use?
A: It depends on the floor in the crawlspace & if you are going to use it for storage.
Q: What tape do I use to seam the material together?
A: Vapor Bond Seam Tape.
Q: How do I attach the liner to the wall?
A: 2 sided butyl tape to seal the poly against the wall & Christmas tree fasteners every 30 inches to carry the weight of the poly.
Q: How long will the liner last in my crawlspace?
A: 10+ years. The material is only degraded by direct UV sunlight; so if it is installed no light will reach it. There is nothing on the ground to deteriorate the material.
Q: How long does it take for me to get the materials?
A: 7-10 days from when the order is placed.
Q: Do I need to seal the vents?
A: Yes, but only if you are doing a conditioned crawlspace. Many crawlspaces use conditioned air from the home to incorporate a dehumidifier to vent/dry the crawlspace.
