Wall lining systems are usually a covering applied to a wall to improve the acoustic properties and/or the thermal insulation of the wall. as well as preventing moisture issues. The wall lining system is put in place by placing laminated gypsum boards over the wall to be treated.

Types of wall lining systems
Depending on the way the boards are fitted to the wall there are two types of systems, direct wall cladding and self-supporting wall cladding. Direct wall cladding is systems where the plasterboard is applied directly to the wall that is being treated. Semi-direct cladding is also available, which is made with metal profiles (usually Omega profiles). These are fixed to the original wall and the laminated plasterboards are placed onto these profiles, and then fixed to them with self-tapping plasterboard screws. For this type of cladding, we can offer FTD OMEGA and FTD OMEGA ULTRA for Omega profiles, and FTD-NIVEL 47 or FTD-MINI for other profiles.

 The self-supporting wall cladding consists of a steel structure fitted with channels (horizontal) and posts (vertical). This covers a larger area compared to a direct wall cladding but offers greater acoustic performance. We offer several acoustic wall mount options for this profile including 3800-3801 and 3802-3803.

Acoustic wall lining systems
This is a wall covering (either direct or self-supporting) that manages different installation factors such as mass, airtightness, elasticity, absorption coefficient and rigidity. The purpose of an acoustic wall lining system is to achieve acoustic improvements by reducing both impact and airborne noise.

What types of wall lining system should I choose?
The type of wall lining system required depends on the needs and objectives to be achieved, the area that needs to be covered and space available. It is worth noting the below points:
– The thicker the cladding the better the insulation.
– Thicker cladding does reduce the amount of usable space
– Wall cladding is a medium to long term investment that makes a house more habitable, therefore increasing its sale appeal and possible value.
– Cladding saves money by improving the houses energy efficiency.

AMEC Acoustics anti-vibration mounts are designed primarily for the construction industry and industrial applications. Firstly, our construction range, such as our acoustic ceiling mounts, work by reducing the vibration transmission (especially structure borne sound) in building structures such as ceilings, linings, partitions and floors. The industrial range such as our heavy machine mounts, work by attenuating vibrations produced by machinery, drastically reducing the vibration and noise output of equipment.

Vibration mounts should be able to work freely in elongation (lengthening or stretching) and also in compression; this is a fundamental requirement in order to obtain the best acoustic results. In addition, the shock absorbers must provide maximum safety to the solution where they are being applied. Correct installation of the mounts will determine their proper functioning.

Choosing the right acoustic mount is essential for the viability of the acoustic/vibration solution. In other words, if the correct acoustic mount is not installed, not only is a good soundproofing result not achieved, but the acoustics of the room may even worsen.

Criteria for choosing a mount:
1. Load: each mount has a load range.
2. Operating frequency (rpm).
3. Are the products for indoor or outdoor use?
4. Weather adversities.
5. Type of sound environment.

Vibration mounts must be installed throughout the whole system. For instance, in wall lining systems, both the uprights (vertically) and the channels (horizontal) must have dampers. On the other hand, to isolate a machine, it is necessary that both the machine and the ducts that are attached to it are soundproofed. Therefore, rigid connections should be avoided, as they would eventually become sound leaks (sound flanking paths).

In our construction range we offer both our standard range and hybrid range of products. The standard range of vibration isolators are designed to operate in medium to high frequency ranges. They are suited for standard, lower cost acoustic systems such as office blocks and residential buildings that are subject to a lower concentration of people and noise.

Our hybrid range of vibration isolators are a higher performance product compared to our standard range, and are suited to environments subject to a higher concentration of noise and people such as entertainment venues and factories. The hybrid range operate in low-high frequency ranges.

In addition to our acoustic mounts we would also advise considering the acoustic strips as they enhance and compliment the performance of the acoustic system. The acoustic rubber strips provide elasticity and tightness to the system.

Over the coming months we will be publishing more articles and also e-catalogues on our industrial and construction ranges, highlighting the key features and differences between our different products. Please continue to check our website blog/latest news section for further updates.
