When combined with the activation strip on our YCS Wall Curtain or YCS Wall Attachment Tape, the patented YCS Magic Sealant/Adhesive ensures a permanent seal every time. This low-VOC product is odorless, non-flammable, and easy to work with, adhering firmly to virtually any surface. Designed specifically to integrate with the other components of the YCS System, it won’t disappoint.

Our proprietary vapor barriers are unlike anything on the market today. Your Crawlspace has been developing quality woven ground vapor barriers made of 100% pure polyethylene for over 15 years to produce a stronger and more lightweight product that will never create undesirable off-gassing (cat urine smell). Our vapor barriers will also never allow mold growth, and they are all covered by a 25-year guarantee. If you’re looking for confidence, any one of our YCS Reinforced Vapor Barrier products will do the trick!

Our YCS Seam Tape and proprietary YCS Seam Weld solutions are designed to integrate with the YCS System to ensure an easy, complete seal. The YCS Seam Tape comes in 3″ and 4″, and it comes with pinked edges to simplify the application process. They can be used with any vapor barrier and are free from chemical odors like other seam tapes.

New YCS Magic Seam Tape is a contractor’s best friend. It’s faster and easier to work with, creating a permanent, waterproof seal. This magic tape attaches to wet surfaces. Once sealed, it cannot be removed.

YCS Seam Weld is the best seaming product for our ground vapor barriers and can be used to attach foam boards without any mechanical attachments. This proprietary solution is odorless and replaces the need for hot welds.

The proprietary YCS Flexible Foam Vent Cover is the final core component of the YCS System, helping to seal crawlspaces quickly and easily. The covers fit into most standard 8″ x 16″ openings and can be easily trimmed. These friction-fit vent covers are designed to simply compress and fit, and they can be ordered with or without a hard cover. With one of our YCS Vent Covers in place, you have a properly sealed crawlspace you can count on.
