When it comes to a good installation of ceilings and technical floors, the main thing is to carry out a good planning and stakeout on site to avoid errors. However, one of the main faults most frequently observed is the use and prescription of ceilings that are not adapted to the requirements of the premises where they are to be installed.
The first step to take into account is to correctly follow the manufacturer’s instructions and all their specifications. As recordable ceilings are composed of plates and profiling, the choice of the weight of the plate and fastening to the low forging is paramount to avoid the risk of falling heavy plates. It is therefore necessary to take into account, from the beginning, a correct planning of the supports and the distribution of the slabs in the structure in which both the ceilings and the floors will be installed. “It is necessary to take into account the type of profiling and fastenings depending on whether they will be spaces that will be registered many times”, comments Roberto Prieto, from Gradhermetic.
The weight factor is very important, once the planning of the supports is done, it is necessary to consider that “the anti-vibratory fastening is adequate for the weight of the false ceiling assembly to be installed. For example, if we are talking about an acoustic false ceiling, given that it normally provides mass and the solution as a whole has a considered weight and, therefore, we have to take special care in the fixings, avoiding any detachment, eluding the ‘domino effect'”, they explain from Senor.
Apart from taking into account the fastenings, with respect to weight, it is important not to replace parts by similar or similar elements, as each system is tested and measured with a series of specific materials and these changes can lead to breakages, or mechanical failures, weight, belay, etc.. However, the opposite case is also a problem, some installers are opting for very economical and lightweight solutions that may constructively solve some acoustic and aesthetic requirements, but usually price optimization is related to reducing the thickness of materials. This can end up causing sagging, lifting of plates in the face of air blows and other undesirable situations that require constant replacement of the plates and unnecessary maintenance.
Another factor to take into account, if we are talking about a recordable false ceiling, would be the avoidance of condensation and thermal and electrical bridge breakage. The choice of a moisture-resistant ceiling can be essential in a room with air pipes and ducts, such as a supermarket, to prevent condensation on the sheet or damage due to leaks.
Finally, in order to achieve an optimum and adequate level of comfort in a space, sometimes it is not enough to install a ceiling that, due to its composition, absorbs the sound produced in the direct environment, but it is essential to act against the noise coming from adjacent rooms in order to attenuate it.
One of the most commonly used elements in this type of construction is gypsum, which “is a natural material that offers many properties by itself, converted into laminated gypsum board, has easy application and a whole series of technical advantages that make it a healthy natural material,” says Rosana Gallego (Knauf GmbH).
On the other hand, Roberto Prieto, from Gradhermetic, believes that “aluminum is the most suitable for its ease of maintenance and durability, aesthetics, color and lightness.
From Rockwool, Alberto Mínguez, analyzes that “in Europe, the most used materials for recordable ceilings are mineral ceilings, segmented in two typologies; Soft-Felt (rock wool or glass fibre) or Wet-Felt (cellulose with agglomerates)”. However, in the Spanish market, “the most used is the plaster ceiling, due to the short drying time of the plaster. In Spain, plaster ceilings, rock wool and/or glass fibre ceilings and cellulose ceilings represent 3⁄4 parts of the market. The remaining part of 1⁄4 is mainly metal, vinyl and wood shavings ceilings”.
Another new material in this field is textiles, where Chus Barroso comments that
These elements are available in various sizes and are fully adaptable to lighting and air conditioning systems. False ceilings and technical floors can be recorded over their entire surface area, allowing the space to be adapted and the installations to be channelled at the same time.
