BLOCK-IT House Wrap


BLOCK-IT contains several innovations that set it apart from other drainage wrap products. A tough outer layer helps maintain a dry building structure, while a breathable barrier and patented channeling system direct liquid away from your home. By keeping moisture out, you prevent rot that can prematurely damage your home and cause unpleasant mildew and mold to develop over time.

BLOCK-IT is also GREENGUARD Gold Certified for low VOC emissions. As a result, it is great for the environment and suitable for use in commercial facilities such as schools, hospitals, and other sensitive environments. Download the BLOCK-IT brochure to learn more.

BLOCK-IT House Wrap Products


In addition to standard BLOCK-IT house wrap, Kimberly-Clark manufactures three additional BLOCK-IT products, which are available through the Wolf Home Products dealer network:

  • BLOCK-IT seam tape for creating a complete weatherization envelope for a house or other building project.
  • BLOCK-IT flashing tape for preventing heat loss and moisture intrusion around siding and door and window openings.
  • BLOCK-IT flex flashing tape for use on angled and contoured surfaces.

All BLOCK-IT products offer excellent performance in all weather conditions and long-term durability when installed by a qualified professional.

Block It House Wrap for Builders and Contractors


BLOCK-IT is also fully non-slip, even when wet, and will not snag on nails, tools, or construction equipment. Contractors and builders alike love working with it for its ease of use and superior value proposition.

More than being easy to use, BLOCK-IT is also a way of giving your clients peace of mind. Rest easy knowing that your projects will last longer and enjoy superior protection from the elements. Ultimately, installing Kimberly Clark BLOCK-IT is a small investment of time and money that will deliver long-term results and increased customer satisfaction.
