Can you mount your TV on a hollow wall?

Mounting your TV on a hollow wall

One question that regularly comes up is whether it is possible to mount a TV mount on a plasterboard or hollow wall. Hollow walls are often built on a metal or wooden framework. In principle, the answer is 'yes' but... it does depend on the situation. A number of scenarios are described below, along with advice on installing a Vogel's TV mount on a hollow wall.

1. How can I find out the distance between the profiles?

Measuring the distance between the profiles

Please note: you do not know whether the upright profiles are correctly fixed to the floor or ceiling. If in doubt, we always recommend consulting an expert..

Currently, builders mainly make use of two types of system, namely walls composed of:

  • A wooden frame or profiles
  • Metal stud profiles

In most cases, both wooden and metal stud profiles are placed at a centre-to-centre (c.t.c.) recommended distance of 600 mm, although in some cases it may be 450 mm. How do you determine the correct distance?

  • For wooden profiles, you check this by knocking on the wall until you find a place that sounds less hollow. Mark this point and then check whether the next upright is placed at 450 mm or 600 mm.
  • For metal stud profiles, you use a pipe finder, which allows you to detect the metal profiles.

2. A wooden frame wall

When you have performed the check and the frame is made of wood, you can continue without issue. You can use a flat TV mount (FLAT), such as theVogel's WALL 3305 or Vogel's THIN 505, (which are both suitable for a 450 or 600 mm frame), which bridges the gap between the two wooden upright profiles. A full motion TV mount (TURN) can be mounted directly on the wooden stud. You can also use Vogel's stud adapter (Vogel's THIN 595). This metal adapter allows you to mount your TV centred between two wooden uprights.

3. A metal stud wall

If it concerns a metal stud wall, the wall must be reinforced with an extra back plate of sufficient thickness (underlayment). This is necessary because the metal stud profiles are only 6 mm thick. If you install your TV mount and TV directly on the profile, there is a chance that the TV will tip over.

It is important for the rear wall to be sufficiently thick (approximately 18 mm, together with the plasterboard approximately 30.5 mm or thicker) and to be securely fixed. You can use a flat TV mount (FLAT), such as the Vogel's WALL 3305 or Vogel's THIN 505, which are both suitable for a 450 or 600 mm frame), which bridges the gap between the two wooden upright profiles. You can mount a full motion TV mount (TURN) directly on the metal stud. A safe solution is to install this mount using a Vogel's stud adapter (Vogel's THIN 595). This metal adapter allows you to mount your TV centred between two uprights.

Please note: when using the Vogel's stud adapter together with metal studs, you will also need to use other mounting materials, which are not included. For the safest advice and results, consult an installer and/or specialist.

4. What mounting materials do I need?

To ascertain what mounting materials you need, drill a hole with a small drill at the locations of both uprights. This will enable you to make a better assessment. You may come across wooden or a metal uprights, for example, and it is also useful for checking the wall thickness. Normally, 12 mm plasterboard is used for a single wall. This is important for deciding the length of screws needed.

For wood, we recommend pre-drilling the holes with a 5 mm wood drill and then tightening the wood threaded bolts with a size-13 socket wrench. If you do not pre-drill, there is a strong chance that the wooden frame will crack, which is obviously undesirable.

Warning: read the warning and installation instructions carefully before using the stud adapter and TV mount. It is extremely important that these products are mounted and/or installed correctly! If the mounting and/or installation work is not carried out in the correct manner, there is a high risk of injury and/or damage to your TV and/or other objects. Vogel's recommends having the mounting and/or installation work for these products performed by a competent installer. Vogel's cannot be held liable for any injury and/or damage caused by incorrect installation. If you wish to install your TV mount on a hollow wall, such as hollow bricks, wooden panels or plasterboard, please contact an installer and/or specialist for the safest results.
