Available in a range of sizes, types, and materials, new sliding patio doors create a modern, insulating opening and provide generous views out. Once the product arrives, it is then necessary to fit it into the opening. This guide keeps the process of installing patio doors simple and gives an overview of the key steps.

For all our patio doors, whether lift and slide, tilt and slide, bifold, or smart slide, the door frames are fixed to the wall in same way. Each patio door type then differs in terms of how the door sash itself is then installed into the frame.

Materials

  • Drilling machine
  • Spirit level & screwdriver
  • Measuring tape & support blocks
  • Protective clothing and glasses
  • Seals

1. Preparatory steps

Before installing a patio door, it is important to have an overview of the steps as well as all necessary tools to hand.

Interior sealing tape or silicone will be needed, as well exterior sealing tape, and expanding insulation foam or pre-compressed tape.

The door surfaces should also be cleaned to prevent dirt from affecting sealing adhesion.

Protective clothes and glasses should also be worn.

2. How to install a patio door frame

The first step of patio door installation is to fix the frame to the wall. As part of this process, either expanding insulation foam or pre-compressed tape should be used. The procedure will then differ slightly based on which option is used – below the images we have provided instructions for both.

Please note that expanding insulation foam should be applied very carefully as it is hard to remove from the frame once dry

  1. Fix exterior sealing tape to the door frame (a)
  2. Place the frame into the opening (b)
  3. Level the frame vertically and horizontally
  4. Insert support blocks at intervals to keep the frame level (c)
  5. Once the frame is stable, re-check the levelling and fix the frame to the masonry (d)
  6. Attach exterior sealing tape to the masonry
  7. Insert expanding insulation foam into the space between the frame and masonry (e)
  8. Apply interior sealing tape or silicone to the frame and wall (f) once the foam is dry and any excess has been removed

Please note that once the pre-compressed tape has been applied, the installer should move through the steps swiftly, completing them before the tape has had time to fully expand.

  1. Fix pre-compressed tape to the door frame (a)
  2. Place the frame into the opening (b)
  3. Level the frame vertically and horizontally
  4. Insert support blocks at intervals to keep the frame level (c)
  5. Once the frame is stable, re-check the levelling and fix the frame to the masonry (d)
  6. Attach exterior sealing tape to the frame and masonry
  7. Seal the space between the frame and wall with interior sealing tape or silicone (f)

3. Installing the panel inside the frame

Because the process of how the patio door should be installed inside the fixed frame differs for each type, we have split the instructions into relevant sub-sections – just scroll down to view them or navigate using these links:

Installing a lift and slide or a smart slide door sash

How a lift and slide or smart slide door sash should be fitted into the fixed frame differs slightly depending on its material. Below you will find the relevant instructions as well as useful images.

  1. Place the mobile sash's wheels onto the track in the middle of the frame
  2. Push this sash (containing the top rail (b)) from the top into a vertical position (a) in the frame
  3. Insert the top rail (b) up into the frame channel and fix all visible screws (d) to the left and right of the panel
  4. Slide the panel to the left and right to fix the remaining upper screws
  5. Secure the anti-lift door stopper (e) with a screw (f)

  1. Push the panel into the top rail (d)
  2. Lean the panel from the bottom into a vertical position
  3. Drop the panel into the wheels
  4. Secure the anti-lift door stopper (e)

Installing a tilt and slide door sash

Key steps

  • Move the sash into the frame
  • Secure the scissors

  1. Insert the panel so that the wheels fit into the track (a)
  2. Lean the sash from the top into a vertical position
  3. Connect the upper scissors between the door and the frame (b)

 

Installing bifold door sashes

Key steps

  • Attach the main sash to the frame with hinges
  • Fix the other door sashes in the same way

With their hinges and function, bifold doors installation is quite similar to that of a French door.

  2. Starting from this first sash, fix the remaining sashes via the hinges to one another
