Stacks Image 4938
WeatherMax Pro Flash™ is a high-performance peel & stick flashing tape that has been designed to work in wet weather conditions. In fact, this product has been test and will adhere to OSB even under water.

Weather-Bloc Systems experience in job site realities developed this tape for the contractors to continue working in less than ideal weather conditions and still have the ability to install a flashing tape that seals and protects. Based on new hybrid adhesive technology called Micro-Grab, this tape performs when other fail.

WeatherMax Pro Flash meets and exceeds ASTM E-2112 for sealing around windows and doors. Manufactured with a high strength, puncture resistant facer, this tapes performs as a great air and moisture barrier.

As part of the building envelope system, WeatherMax Pro Flash can help aid in the reduction of water damage, air infiltration and improve the energy efficiency of the structure.
Basic Uses
This tape can be used to seal duct board, flex duct or sheet metal. Great sealing tape for many high heat applications.

Not Just Duct Tape

Most HVACR contractors spend the bulk of their time focused on the flexible sheeting, support braces, connectors, and airflow - and not necessarily on a less costly tool that can pay big performance dividends: duct tape.

Most of todays HVAC tapes used on duct work are high heat tapes. Most all of these tapes fall short in regards to long-term adhesion performance. This is due to the adhesives (mainly asphalt based) drying out and losing their ability to adhere. Once this happens, they are no long an air barrier and conditioned air is lost. In turn, this causes increased energy costs.

Weather Bloc's DuctTite™HVAC Foil Flashing Tape uses Micro-Grab technology, which insures our adhesive adheres to the ducts. With its re-enforced metalized film, DuctTite has the ability to dissipate heat and not transferring through conduction to the surrounding air. This "flashing tapes" is designed to be strong, yet extremely flexible giving it the ability to contour to the many difficult assembly profiles. Get Energy Smart and start using DuctTite.
