Rigips, s.r.o. is entering the market with a new product – the blue acoustic drywall board. The blue acoustic board from Rigips significantly reduces noise levels in system drywall constructions. It is a professional and economic solution for soundproofing buildings. Thus, Rigips helps to meet a very important criterion in the field of commercial and residential construction, which is peace for work and rest.
The blue acoustic board is a new drywall board whose properties help reduce harmful noise. Thanks to its unique blue cardboard color, the board is easily recognizable. The board is supplied in a fire-resistant version as standard, making it suitable for constructions that require fire resistance.
Exclusive Product The exclusive product from Rigips is used for the installation of internal and inter-apartment partitions, ceilings, and front walls in interiors. Acoustic constructions with the blue acoustic board allow for improved acoustic comfort in all rooms, whether in a new or renovated building. For the first time, a single-layer drywall partition that meets strict standard requirements for sound insulation within an apartment is now available in the market.
Special Formula The blue acoustic drywall board is manufactured according to a special formula. It has a suitably chosen core density, consisting of a modified gypsum crystalline structure with specific damping properties. Thanks to its unique composition, the board achieves high acoustic qualities.
Effective Noise Protection Effective noise protection in construction is becoming an increasingly important topic for architects and designers. For people, quietness is an exceptionally important criterion for living comfort. Continuous noise can even cause serious health problems. At best, noise is considered “merely” a disruptive element. High demands for soundproofing need to be integrated into the project and subsequently ensured to be reliably met in practice. With proper design, both objectives can be achieved. Noise from adjacent rooms can be dampened so much that residents will not perceive it as disruptive. People will be able to live and work side by side in acoustic comfort.
Building Acoustics One area that building acoustics deals with is limiting sound transmission between different spaces within the building. To address this issue, it is necessary to build a suitable sound-insulating construction or material in the path of sound. The basic property expected from such constructions is sound insulation. The construction systems offered by Rigips have been carefully assembled to meet the strictest criteria and have been verified in authorized laboratories.
Laboratory Tests of Acoustic Systems The values of airborne sound insulation achieved during laboratory tests of systems in authorized laboratories have demonstrated the increased effectiveness of the blue acoustic board for noise insulation. These high initial sound insulation values also ensure optimal reliability of the construction systems even after their installation in the building. This provides builders with assurance of achieving the declared values of acoustic insulation. All of this applies, of course, provided that the proper Rigips system components are used.
The installation of acoustic constructions does not differ from the classic installation of drywall constructions. There is no need to change tools, accessories, or methods of execution.
Blue acoustic drywall boards are available in a thickness of 12.5 mm in two sizes 1 250 mm x 2 000 mm, 1 250 mm x 2 750 mm.
Construction Systems for Airborne Sound Insulation The classic approach to solving airborne sound insulation is to place a massive construction in the path of sound. From empirical experience, it can be derived that any doubling of the surface mass of the separating construction will bring an increase in airborne sound insulation by 6 dB.
To achieve the desired sound-insulating properties of internal partitions, it is more advantageous to use lightweight double constructions instead of increasing surface mass. Each such construction consists of a supporting system (wooden or metal profiles) and double-sided cladding with boards (single or double cladding with system boards with a surface mass of one board less than 40 kg/m²), which are separated by an air gap filled with flexible mineral insulation.
The advantage of dry construction (construction made of gypsum or gypsum fiber boards) is the use of the principle of vibrating membranes with an absorbent layer inserted into the gap between them. Such constructions achieve the same sound insulation as massive constructions but at a significantly lower weight.
For example, for airborne sound insulation of Rw = 49 dB, which means that adjoining rooms inside the apartment are very well sound-insulated, the following is required:
Reinforced concrete wall of 100 mm thickness weighing about 230 kg/m²
Solid brick wall of 150 mm thickness weighing about 250 kg/m²
Wall with blue acoustic boards of 100 mm thickness weighing 28 kg/m²
Lightweight front wall constructions can also address the sound insulation of unsatisfactory existing partition constructions. For example, by building a front wall clad with double blue acoustic drywall boards, the sound insulation of the original masonry wall can be significantly improved
Original wall made of aerated concrete of 80 mm thickness, plastered – Rw = 35 dB
Original wall made of aerated concrete of 80 mm thickness, plastered with a front wall – Rw = 63 dB
Original wall made of solid brick of 150 mm thickness, plastered – Rw = 52 dB
Original wall made of solid brick of 150 mm thickness, plastered with a front wall – Rw = 63 dB
Blue acoustic constructions have the following properties:
already in the basic version with higher fire resistance (fire-resistant construction)
easily recognizable by the blue color (easy identification)
due to the small thickness of the construction, larger usable area of the rooms remains
the small weight of the blue acoustic construction means lower demands on load-bearing structures
unique solution for renovations as well as new builds
smooth, health-safe surface
easy installation of utilities within the cavity of the construction
quick construction using dry methods
investment savings
Acoustic systems with the blue acoustic board include:
Acoustic partitions for internal and inter-apartment use
Acoustic front walls
Acoustic ceilings
Used Materials and Implementation The installation of acoustic constructions does not differ from the classic installation of drywall constructions. There is no need to change tools, accessories, or methods of execution. It is necessary to pay attention to the selection of appropriate components, proper installation of the construction, and actual implementation on site according to Rigips' technological principles.
When installing sound-insulating constructions, the following principles must be observed:
The profiles of the substructure must be glued with connecting seals around the perimeter of the construction. For ceilings and front walls, flexible hangers and brackets should be chosen.
Mineral insulation must be inserted continuously.
To meet the declared sound insulation values, the spacing of the profiles of the substructure must not be less than 50 cm.
The junctions of individual parts of the partition constructions (e.g., corners and intersections of partitions) must not contain "acoustic bridges". This primarily concerns the incorrect placement of mineral insulation, the execution of continuous cladding, or the absence of flexible connection of the substructure.
To reduce the impact of sound transmission, it is advisable to interrupt or omit the layer of floating floor screed at the junction of the construction. Similarly, at the junction with a mounted side wall, it is recommended to interrupt the continuous wall cladding board.
For connections of partitions and ceilings, or partitions with each other concerning limiting noise spread in the construction, suitable detail solutions should be chosen.
Fillings of openings should be chosen to meet the requirements for airborne sound insulation of the construction, or their negative influence must be taken into account.
The number of penetrations through sound-insulating constructions must be minimized, and suitable execution and sealing of these penetrations must be chosen.
