GCP Applied Technologies

In February 2016, Grace Construction Products separated from W.R. Grace to become a new company, GCP Applied Technologies. This separation was intended to enable GCP to grow faster, introduce products more quickly and improve service to customers by becoming more focused on them and their unique market segments.
Although the name has changed, GCP is still the brand customers know and trust with time-proven products such as Grace Ice & Water Shield® roofing underlayment and Vycor® enV-S™ weather resistive house barrier. As a new company, they’re more focused on serving who matters most—contractors, homebuilders and remodelers like you.
