AZEK Casing profiles are decorative mouldings typically used flush against a wall, door or window to create surrounds. They can be used as a single profile or combined with other moulding styles to dramatically transform window and door aesthetics. AZEK products are known for longevity and durability. They won't split, crack or rot. They can be installed using traditional woodworking tools and fasteners and for custom applications. Most AZEK Moulding products can be heat formed to create eye-catching curved moulding details. Alternative Applications While AZEK Moulding will look beautiful on your home’s exterior, it’s also great for high-moisture indoor spaces like bathrooms and laundry rooms to prevent the build-up of mold and mildew indoors.
