Maithongcharoen DF-100D door sub-frame casing, made from 100% Polystyrene (PS). 100 mm wide, 8 mm thick, with a factory wood-grain finish — no painting needed. It cases the door frame and closes the joint between frame and wall, making an old frame look new without tearing it out.

MATERIAL PROPERTIES PS
  • Termite and insect proof Polystyrene is not food for termites, so there is nothing to eat and nothing to rot
  • Waterproof, will not swell Holds its shape in damp rooms — fine for bathroom door frames
  • Light and easy to fit Far lighter than solid timber. One person can fit it without loading the old frame
  • Strong and impact resistant Takes the daily knocks a door edge gets
  • No painting, easy to clean The wood-grain finish is applied at the factory. Wipe with a damp cloth
  • Safe and recyclable Non-toxic and safe around people and pets, and the material can be recycled
WHY BUY FROM US
  • One colour range across skirting, cornice, wall panels and door casing, so a whole room finishes in exactly the same tone
