Our last blog relating to Suspended Ceilings discussed the following:
Advantage of installing a Suspended Ceiling.
In this blog we discuss, the more practical aspects of installing a suspended ceiling.
The most popular type of Suspended Ceiling system which we are asked to install is what is commonly described as 600 x 600mm exposed lay-in grid. This system can be purchased from a number of manufacturers, but a popular choice would that supplied by Armstrong Ceiling. Please see the website at http://www.armstrong.co.uk/
If you follow the link to the Armstrong website, you will see that there is a huge choice of different ceiling systems available, but for this blog we will proceed to describe the basic 600 x 600mm exposed lay-in grid system.
The diagram above shows the basic construction. The 600 x 600mm grid is constructed using either 15mm or 24mm wide tee sections which are clipped together using either a hook or stab clip system.
The process of construction is as follows:
1) Fix the perimeter trim to the walls of the room which is to receive the ceiling at the required height. This trim is a white painted ‘L’ section and supports the edge of the tiles at the wall abutments and hold the suspended grid in position.
2) Install wire hangers from the structural ceiling which will support the suspended ceiling below. This wire is secured using clips or anchors to suit the construction of the structural material be it concrete or timber. These wire hangers must be positioned so that it supports the suspended ceiling at a maximum of 1200mm centres in any direction, reducing to 600mm at wall abutments. Additional suspension should also be provided around light fittings and ventilation grilles.
3) These wire hangers support the 3600mm long Main Runners which in turn support the 1200mm long and 600mm long Cross Tees. Care must be taken to ensure that the main runners and the perimeter trim are level so as to produce a perfect result.
4) Following the successful completion of the grid framework, the 600 x 600mm ceiling tiles are laid into the new frame structure to complete the ceiling.
The tiles should be selected to suit the design requirements which were discussed in our previous blog. There is a choice to be made regarding the tile edge detail to be used. Tiles can be square edge of tegular. The square edge tiles produces a ceiling which is perfectly flat across the metal tees and tiles, while the tegular tiles introduces an interesting design feature with the tiles suspended 6mm lower than the supporting tees.
