Maithongcharoen DF-073 door sub-frame casing, made from 100% Polystyrene (PS). 73 mm wide, 30 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
  • A full 3 m length, not 2.4 m We extrude our own lengths, so a 3 m wall takes one piece. Most imported stock arrives at 2.4 m, which puts a joint in the middle of the wall
  • One colour range across skirting, cornice, wall panels and door casing, so a whole room finishes in exactly the same tone
  • Cut to your measurements — send the lengths and quantity in the chat and we cut to what you measured, so you pay for less offcut
INSTALLATION

Fits over the existing frame, whether timber or steel. Use construction adhesive, run as a bead along the length, press firmly and hold until the adhesive sets. Cuts cleanly to a mitre without chipping.

SHIPPING

Every length is wrapped for protection before dispatch. If anything arrives damaged in transit, photograph the parcel and the item and tell us within 24 hours of delivery. We replace it straight away.
