Instruction: Installing a Plastic Door

Installing a plastic door requires precision to ensure that the door closes properly, is secure and lasts for years. Here is a clear guide to installing a plastic door, including tips for a professional end result.

Supplies

  • Plastic door (including frame and hinges and locks)
  • Tape measure
  • Spirit level
  • Wedges and adjusting blocks
  • Drill and screws
  • Mounting kit and PUR foam
  • Caulking gun
  • Screwdriver
  • Vacuum cleaner
  • Chisel or multi-tool (for any adjustments to the recess)


Step 1: Preparing the recess

  1. Check the recess (the door opening) for the correct dimensions. Make sure there is enough space all around for insulation and mounting (approximately 5-10 mm).
  2. Check with a spirit level if the opening is level and square. If necessary, level the opening with mortar or adjusting blocks.
  3. Remove all dirt, dust, old sealant and obstructions from the recess using a vacuum cleaner and chisel.

Step 2: Preparation of the plastic door and frame

  1. Check the plastic door and frame for damage. Make sure the hinges and locks are complete.
  2. Pre-attach any accessories, such as ventilation grilles or sill profiles, to the frame.
  3. Apply compression tape or insulation tape to the outside of the frame for airtight mounting against the wall.


Step 3: Install and align the frame

  1. Place the frame (without the door) in the recess using wedges and adjusting blocks.
  2. Make sure the frame is evenly distributed all around in the recess. Check this with a tape measure.
  3. Use a spirit level to align the frame perfectly horizontally and vertically. Check this on all sides.


Step 4: Fixing the frame

  1. Drill mounting holes through the frame and into the wall. Make sure the holes are evenly spaced, approximately 30cm apart. Start 10cm from the corners.
  2. Fix the frame firmly to the wall with plugs and screws. Do not tighten the screws too much to prevent deformation of the plastic.
  3. Check in between whether the frame remains level. Adjust the wedges or adjusting blocks if necessary.


Step 5: Insulate and seal

  1. Fill the space between the frame and the wall with PUR foam. Do this carefully to prevent deformation of the frame.
  2. Allow the foam to cure according to the manufacturer's instructions.
  3. Cut away excess PUR foam and finish the seams on the inside and outside with a caulking gun. Use a waterproof and flexible caulking for this.


Step 6: Hanging the door

  1. Hang the door in the frame by placing it in the hinges. Make sure the door turns smoothly.
  2. Adjust the hinges so that the door hangs exactly straight and closes properly. Use the adjusting screws on the hinges for this.
  3. Check that the hinges and locks work properly and that the door closes smoothly.

Step 7: Checking and finishing

  1. Check that the door is securely fastened, closes properly and that there is no play between the door and the frame.
  2. Remove all wedges and adjusting blocks and fill the gaps with sealant or polyurethane foam.
  3. Clean the frame and door and do not remove the protective film until the work is completed.


Important tips

  • Weather resistance: Ensure a good seal on the outside to prevent draughts and moisture.
  • Adjustment: After installation, check regularly that the door continues to close properly. Plastic can work due to temperature differences.
  • Clearance: Allow 5mm clearance all around between the door and the frame for smooth operation.
  • Professional help: If you have any doubts about the placement, you can call in a professional.

With this manual you can install a plastic door correctly and durably, so that it functions without problems for years!
