Engineered Terrace Deck In the past, we traditionally made our terrace decking from 100% natural solid teak and hardwood. Due to the environmental concerns and the growing scarcity of precious timber, its increasingly difficult to find good quality teak and hardwood on the market. With our expertise in woodworking field, Sun Wood has developed Environmentally Engineered Teak & hardwood Terrace Decking.Engineered Terrace Deck is composed of 5 mm thick beautifully selected teak/hardwood top layer with an inner composite. E.E.T. (Environmentally Engineered Teak) making the whole structure stronger and dimensionally more stable than solid wood.Engineered Terrace Decking is easily assembled using edge fittings, thereby avoiding unsightly holes on the top surface.
