GREENWELD: ARMORED FLASHING SYSTEM

Reference #

STRENGTH MEETS VERSATILITY

Versatile Solution… Lead Free!

With aluminum reinforcement for superior strength and modified polyvinyl coating for exceptional flexibility, GreenWeld delivers dependable waterproofing protection in one monolithic sheet. Ideal for a variety of flashing applications, this system can even replace lead or zinc products used to flash and seal rooftop drains and pipes – lead free! This is the first material in the world to offer the benefits of lead without the harmful effects of actual lead. As an alternative to lead flashing products, GreenWeld is even easier, faster, and less expensive to install.

Performance & Installation Benefits

Independent tests show that GreenWeld has the same waterproofing properties of traditional lead used to seal roof penetrations. Because it is flexible even at very low temperatures, GreenWeld can be installed in extreme conditions without trouble – down to -4ºF (-20ºC). This material is also very easy to heat-weld which means attractive, strong, watertight seams.

Material

GreenWeld is made up of expanded aluminum mesh reinforcement bonded with a monolithic layer of modified polyvinyl butyral (PVB). A release liner of each side of the material roll makes unrolling material simple and includes a printed grid for simple, accurate cutting. Available in:

Extra-long lengths
Multiple widths
Various colors

APPLICATION TIPS

Required tools may include a sharp knife or scissors for cutting material as well as a heat gun and aluminum hand roller for heat-welded applications
Use the 2”x2” grid printed on the release liner to make cutting material efficient
After application, remove the top protective liner (it can be beneficial to leave the liner in place until the pointing is complete to keep the flashing clean)
Use the aluminum hand roller to easily wrap the material around details and penetrations
Remember to use approved sealant at heat-welded seams and under the material (especially anywhere strong winds are expected)
Use approved adhesive for target patches and to adhere to substrates
