Quickflash HVAC Flashing Panels

Quickflash Weatherproofing Panels provide the natural building industry with the ultimate solution to weatherproofing plumbing, electrical, gas and HVAC wall penetrations and protrusions.

Quick, Reliable Installation

Quickflash is quick and easy to install, the patented, made in the USA flashing panels replace the old, unreliable caulking, tape flashing, and/or sheet metal flashing methods all together--saving the builder thousands of dollars a year from potential moisture related problems such as toxic mold and possible litigation.

Why Take the Risk with Inferior Systems?

Quickflash flashing is a key component in the building process. Quickflash panels complete the building envelope system and offer a no caulk friction seal for reducing liability for moisture intrusion, creating an air barrier, and even preventing insect infestation through the penetrations or protrusions. Caulking breaks down over time. Incomplete and improper caulking of penetrations is one of intrusion. Any time the building envelope is breached, proper sealing is essential. You flash everything else--doors, windows, vents--now you can flash the exterior penetrations as well, so why take the risk?

I spoke with the person in the Technical Support department who listened and understood my complicated circumstances and made the perfect recommendation. I received the product within a couple of days and before the weekend ended, the job was complete and I am very pleased with results. Thank you, Eco Building Products for your support and product recommendation.
