PRACTICAL Coastal Shutters have rabetted overlapping stiles instead of unsightly astragal "gap flaps". Lightblock frames also contribute to maximized light control and privacy. Quick release hinges facilitate easy removal of the shutter panels for cleaning and unobstructed access to windows and doors. The hollow macro-cellular construction of this shutter make them an efficient thermal insulator, lowering heating and cooling costs. The use of Mikron Rigid Vinyl Extrusion RP-5534, a recyclable non-wood material, helps preserve America's forests.
