Flashing Applications

At the heart of ALT Flashing Systems is an integrally reinforced, seamless, cold applied, elastomeric, flexible PMMA resin suitable for a variety of flashing and repair applications on new and existing roofing and waterproofing.

Most roofing and waterproofing failures occur at transitions, penetrations, and flashings. ALT systems address these concerns providing a fully adhered flashing that handles normal building movement and eliminates mechanical terminations and sealants creating a low maintenance alternative to traditional waterproofing flashing and detailing.

Our Flashing Systems are perfect solutions to different types of flashing needs including standalone repairs, metal roof flashing repairs, penetrations, chimneys, drains, rail posts, etc. They can also be used in conjunction with conventional built up roofing Systems (BUR), requiring liquid applied flashing details.

ALT R230 flashing membrane has an excellent bond to most surfaces including asphalt, metal, TPO and PVC substrates. Our flashing systems are easy to install, quick to cure and can be installed as protective roof membrane assembly (PRMA) as well as insulated roofing assembly.

For areas where fabric reinforced membranes would be difficult or impossible to install; ALT R295 Matrix is used to form a monolithic, self-adhering and self-terminating reinforced membrane for flashing and repair purposes. ALT Matrix is a high performance two-component, rapid-curing and flexible PMMA resin with integral chopped fiber reinforcement mixed into the resin.
