MaxiSIDING is composed of cement, sand, cellulose fibers, water and selected additives that have been cured with pressurized steam to increase strength and dimensional stability. It offers the warm, natural look of wood without the knots and voids. It won’t rot or crack, is fire-resistant and resists damage from rain, hail and flying debris. MaxiSIDING offers the appearance of two natural wood grains, smooth and stucco. It can be used in virtually any climate when properly installed.
