How to install a tile or open-cell grid false ceiling

Today we would like to share with you a video tutorial on how to install an open-cell grid false ceiling, following the same procedure that would be used for a tile false ceiling. It is very useful for installers and for anyone who wants an in-depth understanding of how this type of technical ceiling is installed.

To demonstrate the procedure we have chosen the Rejilla Milán model, and you can view the product data sheet via the link. Here is the step-by-step explanation:

STEP 1: CALCULATING THE SURFACE AREA

In this first step, the total surface area where the false ceiling is to be installed is calculated. To do this, the total length and total width are measured in order to determine the perimeter and the material needed to install the false ceiling.

STEP 2: DETERMINING THE HEIGHT BETWEEN CEILING AND SLAB

Calculate the distance between the false ceiling and the slab (plenum) where the grid panels/tiles are to be installed. Once this line has been determined and properly marked, the perimeter angle is installed, screwing it to the wall with suitable screws at intervals of approx. 40 cm between fixings.

Where the profiles meet at corners, they can be mitre-cut to the corresponding angle or simply butt-jointed square.

If preferred, this ceiling model does not require a perimeter angle, so it can be positioned at the desired distance from the wall depending on the look required.

STEP 3: INSTALLING THE SUSPENSION PROFILES

Using M4 or M6 threaded rod cut to length according to the previous calculation, together with the appropriate slab fixing (brass anchor, rocker clip, etc.), the 2.40 m main runners are installed first, spaced in parallel at 0.60 or 1.20 m depending on the type of grid panel/tile to be installed. Once the main runners are in place, the cross tees are then clipped onto the main runners. This forms the final grid into which the grid modules/tiles will be fitted. The spacing between the rods should also be between 1 and 1.20 m.

It is important to use a washer, nut and lock nut to secure the profiles firmly at the desired height and to make the installation robust. Fixing to the slab must only be carried out using the bracket supplied by the manufacturer, fitted exclusively to the main profiles.

STEP 4: INSTALLING THE GRID MODULES OR TILES

The grid modules are fitted by aligning the framework of each module with the notches provided in the profiles for this purpose. Once installed, the aesthetic result is a completely continuous ceiling in which the grid structure formed by the suspension profiles is integrated into the false ceiling and goes completely unnoticed.

Tiles are simply laid onto the grid formed by the main runners and cross tees. It is worth noting that, depending on the type of suspension grid selected (exposed, concealed or decorative), different aesthetic results can be achieved in the technical ceiling.
