Flexible Drip Cap Flashing for Exterior Arched Openings

B.H. Davis Company offers this new bendable polypropylene drip cap flashing.
As you can see from the photos below it is both flexible enough to bend around
a radius opening yet rigid enough to maintain a smooth matching curve.




The above photo shows the four available colors:

(shown left to right)
BLACK
BROWN
WHITE
and
PAINTABLE BLACK

(Note: As of April 1st, 2008 the paintable flashing is being produced in
a UV resistant BLACK material rather then the old off-white color shown in the photo.)


The cost is $ 2.50 per foot in 6' lengths.
(Note that you need to call to order...there is no online ordering.)

This new product solves the serious problem of how to keep
water out from behind exterior curved mouldings.  Without proper
flashing water gets behind the moulding and channels down
to the hidden window jamb and wall framing below.  Over time
this rots out the trim, window or door frame and the wooden
side walls of the building.  We make many replacement mouldings
for situations where proper flashing was not used and the original
trim, and often much more, has succombed to deterioration..

IMPORTANT:  caulking trim to prevent water penetration is
at best a temporary solution.  Even though high quality caulks are
guaranteed to last for many years, they do not prevent moisture
from seeping through in a horizontal sealing application. 
Within a few years of installation wind, weather and wood
movement will cause the caulk seal to fail and water WILL
penetrate behind the window trim. A quality window or
door installation will always incorporate some form of water
penetration protection, either in the form of a wide ceiling
overhang or proper bendable flashing, such as copper,
lead, vinyl or this new polypropylene product.
  

The flashing cleanly hugs the shape of most any
radius top window or door.  It is available in
6' lengths and multiple sections are easily joined
together for longer runs.  One piece is long enough to
protect a typical 36" diameter 1/2-round opening.







Here you can see special raised lips that force water towards
the outer edge of the flashing.  The drip cap is easily installed
right over the sheating or house wrap just prior to installation
of the siding.  Note that a few staples or small nails will
hold  the drip cap in place until it is covered by the siding.


 




In this photo you can see the integrated kick-out
panel at the lower end of each flashing section that shoots
the water out and away from the side of the building.
