We stock this flexible drip cap product in all three colors so we can
supply it along with our custom made wood curved mouldings.

This curvable drip cap flashing is flexible enough
to bend around a tight radius opening yet rigid enough to
maintain a smooth matching curve.

As you can see in the dimensioned drawings below it is designed to 
cover an exterior moulding up to 1 1/4" thick.  However it can be used
on thicker mouldings with a small modification to the moulding.  
By cutting a 1/4" deep rabbet into the front edge of  moulding the small
drip cap nosing can drop into that notch and water will be forced out
and away from the wall.

(Note:  scroll to the bottom of the page for detailed specification drawings.)

This flexible drip cap 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 instalation 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.

Flexible Drip Cap Flashing

Here you can see special raised lips that force water towards
the outer edge of the flexible 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.


Bendable Drip Cap Flashing

In this photo you can see the integrated triangular kick-out
panel at the lower end of each flashing section that shoots
the water out and away from the side of the building.
This may be cut away if your application works better without it.

At B.H. Davis Company we are concerned
about the long term protection of our high quality
custom made mouldings.That is why we have invested
a great deal of time in searching for a flexible drip cap
flashing that is reasonably priced, easy to install and which
will provide many years  of  water shed protection.  We feel
we have found such a prduct in both of these flexible drip cap
flashings As such we recommend one or the other to all our
customers purchasing our exterior curved mouldings.

There are many existing curved opening installations that
were not properly protected by drip cap flashing.  Plus
many more arch top windows and doors are installed
every day.  As such even though we stock these two
flexible drip cap products to supply with our own
custom radius millwork they are available to
anyone who needs to protect an exterior
arched opening from the weather.
