A WPC door frame is installed the same way as a wooden one. Your carpenter uses the same saw, drill and screws. The difference is that WPC does not need termite treatment.

What You Need

  • Two vertical posts and one horizontal (head) piece of the right size
  • Fine-tooth saw or a mitre saw
  • Drill, screws and wall plugs or hold-fasts
  • Spirit level and measuring tape

Step 1: Cut The Posts And Head

Cut the two vertical posts to the opening height and the head piece to the opening width, allowing for the joint you will use.

Step 2: Make The Corner Joints

Join the head to the posts using one of the standard joints below. Screw the joint; do not rely only on adhesive. WPC frames are joined with screws.

Step 3: Fix The Frame In Wall

Place the frame in the opening, check it with a spirit level on both posts, then fix it to the wall. Keep the frame square so that the door closes evenly.

Tip: in bathrooms, fix the frame before tiling so the tiles can finish neatly against it.

After Fitting

Clean the frame with a damp cloth. If you want a different shade, the frame can be painted, polished or laminated. No termite treatment or regular polishing is needed.
