Are you looking for plantation shutters built to stand up to high moisture areas? Alumacore shutters are completely moisture resistant; they are engineered for high humidity areas such as bathrooms, kitchens and homes built along coastlines. Wooden shutters and Medium Density Fiberboard (MDF) do not hold up to moisture and high humidity like our reinforced PVC, Alumacore. Wood and MDF shutters will eventually warp over time in a humid environment due to the fact they have exposed areas that let in the moisture. One of the greatest advantages of Alumacore in a humid area will be the ability to perform for a lifetime with no warping of louvers or peeling of paint. Alumacore was invented to last a lifetime no matter the environment the shutter is installed in. There is a reason why we are called America’s most durable shutter.
