Our high thermal efficiency doors offer lots of advantages when compared to contemporary veneer or solid wood
exterior doors. These doors are produced using an aluminium layer sandwiched between high quality exterior
plywood. The core of the door consists of a hardwood framework around an extruded polystyrene sheet (XPS). The
aluminium sheet acts as a water barrier to stop moisture penetrating the core of the door, to help prevent bowing or
warping.The XPS sheet gives the door its high thermal efficiency. The hardwood frame can be ordered to a width to
suit all hardware in the market today and also offers the possibility for re-sizing of the door. The doors can be
delivered primed or using a veneer and pre-lacquered using our Sikkens water-based coating system.
