The KWP exterior siding is a wise choice for your exterior cladding work. The Tru-Align(TM) interlock system allows for a precise horizontal alignment, easier installation and extra rigidity with heavy-duty 1/2'' thickness and superior design that renders the nails completely hidden. The panels resist termite damage, buckling, delamination, fungal decomposition, peeling and splitting. The 11'' wide panel simulates 2 5'' planks resulting in a faster installation while the baked-on finish requires very low maintenance. The siding, offered here in acadia is available in the full palette of designer colours. The panels measure 1/2'' x 11'' x 144''. The siding made in Canada is backed by a 50-year warranty against cracking, denting and hail damage and a 25-year warranty on the finish.
