DELTA®-FAS CORNER is a durable, one-piece polymeric corner accessory that helps ensure air- and watertight corners for windows and doors in DELTA® air- and water-resistive barrier system installations.

The product is composed of a highly flexible thermoplastic elastomer (TPE).

The one-piece product is easy to install and provides security for areas that are notoriously difficult to detail correctly. It’s UV resistant and can withstand wind pressure, preventing air or water leakage at critical areas.

It may be used in new or retrofit applications to make corners in windows and doors air and water tight in combination with an air- and/or water-resistive barrier.

The dimensions are: 190 x 40 x 150 mm (7.48” x 1.57” x 5.7”). 40 pieces are included per box.
