    • The 1/4 in thickness eliminates the need to modify adjacent thresholds when abutting to carpeting, wood flooring and other common flooring materials
    • PermaBase® resists the growth of mold and mildew achieving a panel score of 10, the highest score possible, per ASTM D 3273
    • 1/4 in PermaBase® can be used for counters and is ideal for applying directly over laminate or other wood surface countertops
    • PermaBase® has a lower moisture absorption rate than other backer boards, which ensures an accurate open time and a better bond
    • Can be cut using a standard utility knife instead of specialty tools or expensive power tools
    • Homogeneous core has fewer voids and provides a very clean score and snap
