Innovation built on experience



The exceptional robustness of  DCT LB extruded polystyrene (XPS) rigid insulation and long-term thermal performance helps to ensure energy efficiency in a wide range of residential and commercial construction applications.

With long term proven performance and creep data,  DCT LB XPS insulation is an ideal engineered product that designers may confidently specify in today’s increasingly highly insulated designs. For sandwich panel cores, the lightweight, close tolerance, dust-free surface of DCT LB XPS allows for excellent bonding to a wide variety of sheet materials.

DCT LB XPS rigid thermal insulation has been specifically designed to withstand severe dynamic loads and stresses which may eventually lead to fatigue and failure. It is specially designed to resist such force and in tests has been shown to perform extremely well under dynamic load cycling.
