This is the top favourite among our patterns. LDC ALTA has a concealed mounting, which gives your facade or project a smooth look. This pattern can be fire-retardant treated with the 100% natural fire-retardant Burnblock® to the desired reaction to fire class. A more exclusive wood product, LDCwood® ThermoWood® Ash provides an elegant eye-catcher: knot-free, smooth and sleek. LDC ALTA in Thermo-D Ash is impact-resistant and thus extremely suitable for terrace covering. Thermo-D Ash from LDCwood®, both European and North American, is always FSC®or PEFC certified.
