Application Methods
Self Adhered
Polystick P HT is a self-adhered high-temp waterproofing underlayment for use under metal and various other roof coverings. The top surface is composed of a UV resistant high strength polyolefin composite film with Hi-Tread™ slip-resistant coating which is mated to a high-temp SBS (elastomeric) self-adhered compound. A siliconized split-release paper provides quick and accurate installation.
This carrierless membrane is highly flexible; ideal for flashing around roof penetrations and transitions and other critical areas.
Although Polystick P HT is designed for metal roof coverings, this versatile underlayment can also be installed under asphalt shingles and other approved roof coverings.
