HardiePlank® Lap Siding · Cedarmill · 5/16"x7¼"-12' HardiePlank cladding is a versatile weatherboard that offers the texture and natural beauty of timber while delivering the maintenance-free durability of fibre cement. Available in a choice of two textures, HardiePlank can also be installed horizontally, vertically or diagonally, providing the flexibility to create any design. HardiePlank works equally well as a ‘full wrap’ cladding solution or as an accent that complements traditional building materials such as stone, wood and brick. Made from an advanced material that’s five times thicker than typical vinyl cladding, HardiePlank is fire, moisture, rot and pest resistant. It’s unaffected by rain and hail damage and can be installed to withstand winds of up to 150 mph.
