How to install RTA doors

Installing ready-to-assemble doors

Ready-to-assemble doors offer a much easier installation process than standard doors. In this section, you will find out more of what the installation process entails.

How much DIY knowledge is needed to install bifold doors?

Anyone with some DIY knowledge can install Ready-to-assemble bifold doors. Unlike standard bifolds, RTA doors do not require specialist knowledge.

Vufold’s ready-to-assemble doors arrive pre-machined (the only machining required is to fit the door handles) and pre-sized to your specification. The track and cill are already fitted to the frame, so the door frame simply needs assembling with the screws provided.

Hardware fitting locations are either already pre-drilled or marked very clearly. The Vufold hardware provides installation into the brickwork. The tools provided include almost everything you need for full installation, including drill bits.

Each range and size of bifold has a specific set of instructions. The instructions are designed to be as clear and concise as possible. Every step is clearly indicated with additional illustrations for clearer information.

Vufold believes that anyone with some DIY knowledge can install RTA doors. You can view some installation manuals on our website to get a better understanding of the level of knowledge required.

Tools required

While Vufold provides most tools required for installation, you will still need to source some basic tools, including:

Drill hand drill

Tape Measure A picture of an extended tape measure
Philips Screwdriver A picture of a Philips Head screwdriver

Measuring for an RTA door

Before fitting a bifold door, you will need to measure the opening carefully and accurately. Fortunately, measuring for bifold doors doesn’t need to be particularly difficult.

To measure a space for bifold doors, follow these four steps:

  1. Measure the width in three separate levels (bottom, middle, top)
  2. Measure the height from top to bottom at three separate places (left, centre, right)
  3. Subtract 5mm - 10mm from the smallest measurements
  4. Check that the aperture is a perfect square by measuring the diagonals from corner to corner

5mm - 10mm needs to be subtracted from the measurements to ensure there is enough space to fit the bifold and the frame. If you do not subtract the 10mm, you may run into fitting issues which can be costly to rectify.

Installation process for ready-to-assemble doors

The installation of a ready-to-assemble door is a much simpler process than a standard bifold door. This ensures that any knowledgeable DIYer can install their own Vufold bifolding door.

While each range and size of bifold has its own set of specific instructions, the basic installation steps are similar:

  1. Assemble the frame (12 Screws)

    Assembling the frame simply requires placing the frame and hardware in the indicated locations and securing them with screws. The top track can be installed before fixing the frame into the brickwork.

  2. Fix the frame into the brickwork opening, square up and level

    Fixing the frame into the opening is a relatively uncomplicated process. You must ensure you follow the instructions precisely to ensure no mistakes are made. The frame must be square and level with the tolerances provided in the instruction manual.

    Once the frame is fitted into the opening, you can proceed to fit the hardware.

  3. Fix the hardware to the doors and the doors to each other

    Your instruction manual will provide an overview of door and hardware arrangements. Each door will have its own specific arrangements you will need to follow. The manual will provide instructions based on whether you have decided the bifold to open left or right.

    The basic hardware steps are:

    1. Fitting the dropbolts
    2. Fitting the pivot doors
    3. Fitting the other doors (depending on the size of door set)
    4. Fitting the weather seals to the doors
    5. Fitting the lock and handle
    6. Fitting the catches

    All hardware installation locations are either pre-drilled or clearly indicated for easy installation.

  4. Adjust door height and width if needs

    Vufold has designed their doors to ensure any adjustments are as easy as possible. Unlike standard bifold doors, Vufold RTA doors feature easy adjustments which require very basic tools.

    To adjust the height:

    • Use an Allen key (provided) or a spanner and screwdriver (depending on the range)
    • Twist clockwise to raise door height
    • And anti-clockwise to lower door height

    To adjust the doors left or right along the track:

    • Use a screwdriver
    • Ensure the doors are fully open
    • Locate the top and bottom pivot hinges
    • Use a screwdriver in both to adjust until satisfied
