E3 Pre-Laminated MDF Boards
E3 Pre-Lam boards bring together strength and design, crafted to meet the highest standards of quality and finish. Available in a wide range of shades, textures and colours with German paper laminates, our boards are extra dense, moisture resistant, anti-fungal and protected against borer & termite attack.
Our Pre-Lam range is offered across multiple grades — HDMR, Exterior Grade MDF, Interior Grade MDF and Boil Guard — and comes as one-side laminated, both-side laminated, one-side bare or both-side balancing boards, making it suitable for residential as well as commercial interiors.
