## Features

- Start Your DIY Project Correctly: To undertake crawl space encapsulation, even under the best conditions, is daunting. You need the right tools and suitable materials, so to save time and trouble you need a strong double-sided tape that can stand up to the elements’ abuses and keep your crawl space dry.
- Usage: Ideal for environments with fluctuating temperatures and high moisture, specifically crawl spaces. An ideal replacement for messy caulks, this Butyl Tape is the perfect tape of choice for you when it comes to attaching vapor and moisture barriers during your crawl space encapsulation.
- Strong Sealant: Double-sided tape with great adhesive mass means the product will seal troublesome leakage and keep barriers in place to crawl space surfaces. This tape works with most adhesives and sealants and will not bleed or stain materials.
- Weather Resistant: The Butyl Tape has a temperature installation tolerance in both extreme cold (0°F) and high temperatures (300°F). Can be exposed to UV light for six months without issue.
- Additional Features: Double-sided butyl tape provides a watertight seal to unprimed surfaces such as limestone, brick, concrete, and other basement foundations. Self-seals around other fasteners or nails.
