Difficulty level

Way

Tools and materials needed

A spirit level.
A pencil.
A mason rule.
A jigsaw with a metal blade.
A bell saw.
A screwdriver.
A grinder or shears.
Ankles.
Insulation panels (no bulk).
A spirit level.
Metal profiles for walls.
Basic metal profiles.
Bearing metal profiles.
Plasterboard.
Screws for plasterboard.
Quick suspensions (usually supplied with the rails).
From the acoustic sealing strip.
Special coating.
A plate lifter.

Step 1: Prepare the media and hardware.

With the mason's rule and the spirit level, draw the location of the false ceiling on all four walls. Remember to take into account the thickness of insulating panels and drywall.
With the grinder or shear, cut all the profiles according to the width and length of your part.

Step 2: Install the profiles.

With dowels, fix the wall profiles on the tracks provided for this purpose. During this operation, make sure with the spirit level that the profile is parallel to the floor and the ceiling.

Screw on the ceiling fast suspensions that will be used to maintain the basic profiles that will be placed between the wall profiles. Put in place the basic profiles which will then be screwed to the suspensions.

Then install the load-bearing profiles, perpendicular to the base profiles, using cross-connectors. The style of mounting and the number of rails required often depend on the supplier and are usually indicated in the installation kit.

Step 3: laying insulation.

(If you are applying mineral insulation, protect yourself by wearing gloves, long-sleeved clothing and a mask or scarf on the nose).

Cut the insulating panels with a saber saw or with a bread knife, slightly larger than the gap between the profiles.
If necessary, make room for electrical connections (holes and ducts).
Then slide the insulation panels between the profiles.

Step 4: laying plasterboard.

Using the hole saw, cut into the drywall the locations for the electrical installation.
If necessary cut out the drywall with a jigsaw.
Then fix the drywall perpendicular to the support profiles, screwing them every 20 cm. During this operation, you will need to be thorough so that the screws sink well perpendicular to the rails. You will continue to screw until the head of the screw is fully inserted into the plaster.

Step 5: the finishes.

Place acoustic sealing strips at the plate joints and apply a special joint seal over it.
You will also use this coating to seal the holes formed by the screws.
It only remains for you to paint or coat this false ceiling at your leisure.
