The YCS Crawl Curtain is the smartest, easiest, and fastest way to properly seal foundation walls and piers. The wall and pier curtain liners are pre-rolled* to fit the job, speeding up the install process. The built-in activation strip and the YCS adhesive will permanently seal to virtually any foundation, brick, block, or field stone, dirty or wet, with NO mechanical fasteners. The liner is bright white on the front and blue on the back, so the activation strip can be easily identified. Additionally, each roll is individually wrapped to ensure the roll stays clean while transporting the rolls through the crawlspace. Never again worry about damaging your foundation wall with nails and pins! The YCS Crawl Curtain is the most efficient way to attach and seal a crawlspace. Safe, simple, sealed, in half the time. Please see our videos for more information. This curtain is 11mil.
For higher foundation walls, consider using YCS Wall Attachment Tape.
To attach the curtain to a surface, Magic Adhesive is required – sold separately
*Pre-rolled for your convenience to protect the liner from dust, dirt, or moisture to ensure better tape seams, all while saving labor time and wasted material.
