Door Installation

The longevity and functionality of modern interior doors hinge not only on their inherent quality but also on the precision of their installation. Errors during this crucial process can compromise the door’s integrity, leading to decreased quality and a shortened lifespan.

Particularly, inadequate installation may result in significant heat loss, exacerbating energy inefficiency.

To mitigate the risks associated with improper installation, seeking assistance from experienced professionals is highly advisable.

While this may entail additional expenses, it ensures meticulous installation and ultimately preserves the door’s performance.

These considerations apply universally to all types of doors, whether for entrances or interiors. Nonetheless, specific guidelines and nuances govern the installation of each type, underscoring the importance of meticulous planning and execution.


In the following discourse, we will delve into these intricacies, elucidating the essential rules and insightful tips for a flawless installation process.

Step-by-step guide to installing exterior metal-plastic doors

Metal-plastic entrance doors have gained significant popularity in the contemporary market, serving not only as office or balcony fixtures but also as primary entrance solutions. With their sleek aesthetics and numerous advantages, they offer a compelling choice for many homeowners.

To embark on the installation journey, you’ll need to gather the following tools:

  • Hammer
  • Bubble or laser level
  • Cordless drill
  • Screwdriver
  • Anchor dowels
  • Screws
  • Mounting foam
  • Sealant
  • Measuring tape
  • Pencil
  • Gloves
  • Spacers for securing the door frame

While installing an entrance door may seem daunting at first, with the right approach and preparation, the process becomes manageable.

Let’s delve into the step-by-step process:

  1. Preparation Phase

    • Clear the workspace and ensure ample space for maneuvering.
    • Clean the doorframe hole from dust and plaster, applying primer if necessary. Unlike traditional doors, installing aluminum doors typically doesn’t require expanding the doorway, saving time.
    • Leave a gap of approximately 15mm between the door frame and the wall during box installation.
  2. Door Leaf Removal

    Take off the door leaf from the hinges, separating it from the box. This step facilitates easier installation.

  3. Fastener Preparation

    Select suitable fasteners, such as anchors or brackets. If opting for anchors, drill holes for screws accordingly. For brackets, insert them into the grooves from the opposite side and drill screws through the box.

  4. Fastening Process

    Begin by securing the upper part of the door frame, followed by the lower part. Install screws based on the intended side of the support.

  5. Direct Installation of Entrance Door

    With the frame securely fastened, proceed with installing the entrance door into the frame, ensuring proper alignment and adjustment.

By adhering to these steps and heeding the advice of seasoned professionals, the installation of an exterior metal-plastic door can be executed flawlessly, guaranteeing optimal functionality and longevity.

Crucial steps for installing exterior door box and finalizing installation

Now that the preliminary steps are complete, attention turns to the installation of the box, followed by the final touches to ensure optimal functionality and insulation.

Here’s a breakdown of the process:

Installing the Box

  1. Positioning the Structure:

    • Place the box within the prepared hole, ensuring an even distance on both sides.
  2. Alignment and Fixation:

    • Use a level to align the plastic frame or box, securing them in place with wedges or fixing plates.
    • Wedges or fixing plates should be positioned beneath the box to provide necessary support.
  3. Securing the Box:

    • Professional installers typically use mounting plates to affix the box to the walls, enhancing stability.
    • Temporary fixation plates add rigidity, and the structure is rechecked with a level before finalization.
    • Secure the box to the wall using anchors through designated mounting holes, without fully tightening the screws.

Final Installation Stage

  1. Door Leaf Integration:

    • Insert dowels and gently tap them with a hammer, then lightly tighten the screws on the side with the hinges.
    • Attach the door leaf, ensuring uniform gaps between the leaf and the box, and confirming smooth operation of the door.
  2. Trimming and Sealing:

    • Cut or trim any excess blades to the level of the box, preferably using plastic blades for their stability.
    • Fill the gaps with foam, applying half the volume from the outside and the remaining half from the inside to prevent voids.
    • Ensure the door leaf remains closed until the foam is completely dry, then trim any excess foam.
  3. Sealing Joints:

    • Seal all joints with an appropriate sealant, such as acrylic, silicone, or polyurethane, to safeguard against moisture intrusion.
  4. Fitting Fittings:

    • Install the necessary fittings, including door closers if desired, to enhance functionality and security.

The correct installation of the entrance door is paramount, as it directly impacts both heat and sound insulation.

By meticulously following these steps, you can ensure the integrity and efficiency of the installed door, providing long-lasting comfort and protection for your property.

Tips for installing interior doors

When it comes to selecting interior doors, practicality often takes precedence, leading to a preference for affordable options. Among these, interior doors crafted from the REHAU profile stand out for their practicality and cost-effectiveness.

While metal-plastic interior doors offer great convenience, their correct installation is crucial. Before commencing installation, gather the necessary accessories:

  • Pencil, ruler, tape measure, and compass
  • Screwdriver or drill
  • Sealant, dowels, and mounting foam
  • Rubber hammer, building level, cordless drill, gloves, and chisel

Before diving into installation, accurate measurements are imperative to ensure a precise fit.

Key Pre-installation Checks

  • Verify the integrity of the door and its packaging upon receipt.
  • Confirm that the door’s dimensions align with the measurements.
  • Ensure all necessary components, such as screws and plates, are present.

Preparation and Installation Steps

  1. Preparing the Openings

    • Clean the work area thoroughly, removing any dirt or debris.
    • Clear out any previously installed structures to create a clean and dry environment, crucial for a successful installation.
  2. Frame Insertion and Leveling

    • Insert the frame into the prepared hole and secure it with screws, gradually leveling it.
    • Ensure equal distances on both sides of the structure, avoiding over-tightening screws to allow for adjustments later.
  3. Placement of Wedges and Spacers

    • Install plastic wedges and spacers along the entire frame to ensure the door aligns correctly.
    • Verify alignment across the width of the opening at the top and bottom, ensuring a snug fit around the perimeter.
  4. Leveling and Fastening

    • Check the level and ensure the base is properly aligned.
    • Secure the frame with a screwdriver, avoiding over-tightening to prevent deformation.
    • Drill holes and commence fastening, ensuring the final tightening is done at the last stage of installation.
