Specifications

Better Service. Better Products
Available in a variety of sizes and materials, we
have a FAN SHUTTER to t your particular require-
ments be it low light, low maintenance or low cost.
The true airfoil design of our shutter blades make
them extremely eective allowing for very little
performance loss. Simple to install and built to last
a lifetime, Cumberland shutters can provide an easy
and aordable means of controlling incoming light
and building climate.
Cumberland PVC SHUTTERS come in white
or black, and are very low maintenance and
easy to clean. The black shutters are used in
reduced lighting applications. GALVANIZED
SHUTTERS have galvanized frames, with
epoxy painted blades to reduce rusting, allow
easy cleaning and provide additional pro-
tection. ALUMINUM SHUTTERS oer great
durability in any environment.
