As a Green Builder we are always looking at the newest developments in green design. Today the folks from Siga were kind enough to come by and show us their energy efficient air sealing products.

We recently finished a Passive House renovation of a Harlem brownstone and worked closely with the air sealing supplier 475. They sell Pro Clima tape and it worked really well.
Siga seems like a great product too and I welcome the increase in air sealing options to the NY market.
The three key benefits of Siga are its outstanding adhesive qualities (its sticks to any surface), its vapor permeability, and its rain driven protection. Not to mention all their products are VOC free and are made with green technology.
They are certainly worth checking out: http://www.sigacover.com/us/
