WOOLTECH Wool Acoustic – layered wall panels – visible fastening – Pruszyński
Mineral wool is used in the construction of facilities for many industries: industry, trade or public utility, as well as in single-family housing and households – wherever insulation of external walls, partition walls or attics is necessary. Among the wide range of sandwich panels with a wool core in the Blachy Pruszyński offer, the WOOLTECH Acoustic wall panel is available, i.e. a sandwich panel with a mineral wool core with increased sound absorption parameters. The materials used in it are mineral wool from top producers and sheet metal claddings in a protective coating, which are additionally perforated. It is worth emphasizing that this is a second-generation wool sandwich panel, produced on the most modern production line in the country and this part of Europe.
The popularity of mineral wool in light industrial construction results from its excellent parameters – it is a non-flammable, vapor-permeable and sound-absorbing material, and at the same time it is characterized by high resistance to mold and fungi.
Working in conditions of increased room noise levels, typical for certain industries and crafts, is not only burdensome for employees but also requires additional actions from entrepreneurs as mandated by the Labor Code. One way to protect employees and the building’s immediate surroundings from the effects of noise is the use of sound-absorbing wall sandwich panels, which significantly minimize this problem — such as our WOOLTECH Acoustic offer — a wall sandwich panel with a mineral wool core and a perforated internal cladding.
In our offer you will find boards with different properties with a core of mineral wool. In the case of our company, this is the second generation of those products that was based on market experience, numerous research, as well as using the latest technologies available. The production is implemented on a completely new production line, launched in 2020.
The acoustic wall panel is a sandwich panel with a mineral wool core, known for its high thermal and insulation properties. In the case of the Blachy Pruszyński offer, similar to other 2nd generation sandwich panels, the acoustic panel is constructed of two layers of steel sheet claddings and a structural-insulation core made of mineral wool with a density of 115 kg/m3. The external claddings are made of 0.5 mm thick steel sheet, covered with metallic and organic coatings characterized by high resistance to atmospheric factors, rust, or mechanical damage. The introduction of the perforation process during production has significantly improved the sound absorption parameters of the wall panel, making it an excellent product for soundproofing rooms; these features are possessed by the modern acoustic sandwich panel from the Blachy Pruszyński brand, offered under the name PWS2-MWA-ST.
The excellent acoustic properties of the modern PWS2-MW-ACU panel are ensured by the perforation made during production. It works in such a way that sound waves refract and enter the panel’s interior, which, thanks to the soft structure of the wool, dampens them and, as a result, does not reflect the sound back out:
The numerous advantages of this product, which can be included in:
In summary, 2nd generation acoustic sandwich panels with a mineral wool core improve working conditions in the enterprise by absorbing noise and providing excellent thermal insulation, while simultaneously limiting the escape of noise outside the building.
The use of acoustic sandwich panels is mainly recommended for industry — in production halls, mechanical plants, and warehouse centers — but also in public utility buildings such as sports or entertainment halls and shopping malls. These are buildings that must meet high requirements regarding fire resistance and acoustics. The acoustic sandwich panel can be used as:
In short, the use of acoustic sandwich panels with a mineral wool core is effective wherever there is a need to soundproof walls and improve the comfort of residents or users of spaces exposed to noise. The choice of panels depends on the type of noise source, as detailed in our Sandwich Panels Catalogue, Acoustics Section.
In the offer of the Pruszyński company, the Wool wall panels system includes standard models (with a visible lock), plus (with a hidden lock), eco (lower core density, reducing purchase costs) and a roof (intended for roofing) with an effective width of 1050 or 1150 mm .
The PRUSZYŃSKI offer includes two basic WOOLTECH sandwich panel systems for walls with visible joints, which include the STANDARD (base model) and ACOUSTIC (perforated internal cladding) models with an effective width of 1050 or 1150 mm. Both STANDARD and ACOUSTIC panels are fully compatible in terms of joints with the PIRTECH line. These include:
Standard family products are models with a thickness of 60 to 220 and length 1150 mm or 1050:
The second category consists of modern wall panels with enhanced acoustic insulation parameters (PWS2-MWA-ST), which result from the appropriate combination of specially developed perforation of the internal cladding and the physical properties of the core (mineral wool). WOOLTECH Acoustic panels have a thickness from 60 to 220 mm and an effective width of 1050 mm.
Second-generation WOOLTECH Acoustic mineral wool panels are characterized by very good sound absorption coefficient ($\alpha_w$) properties – it is 0.65 for all variants of our panels. Additionally, the sound insulation indices of all our panel variants successfully meet the latest standard in this series from October 2015, designated as PN-B-02151-3:2015-10, achieving the following minimums:
This product is therefore ideal for the construction of buildings whose purpose involves noise production inside, as well as for securing rooms that require dampening of noise, echoes, or vibrations.
Unlike other wall panels, in the production of perforated panels, PRUSZYŃSKI uses a different grade of adhesive specially adapted for perforated panels, which is applied at the junction of the two metal claddings and the mineral wool core. This procedure compensates for slight changes in load-bearing capacity parameters. Therefore, the installation location of acoustic panels should result from structural calculations and be specified by the architect.
Furthermore, the acoustic sandwich panel in our offer is available in two variants: with a visible joint and a hidden joint, which is best suited where the investor prioritizes an aesthetic effect. As with standard PRUSZYŃSKI wall panels, you can choose the external profiling of the metal cladding (trapezoid, micro-trapezoid, wave, nano-wave, or flat) and the type of coating (polyester gloss/mat, polyurethane, HPS200, aluzinc).
Acoustic wall sandwich panels with a mineral wool core are suitable for various types of structures, and their fast and simple installation is enabled by matching through-fasteners. PWS2-MWA-ST sandwich panels can be installed on steel or concrete substrates. They are connected to the steel structure using appropriate self-drilling fasteners. In particular, these should be fasteners designed for fixing panels to structures with a maximum wall thickness of 14 mm, equipped with vulcanized EPDM washers. The working thread diameter is 5.5 mm.
In the case of steel structures with a thickness exceeding 14 mm and concrete structures, it is possible to use other fasteners:
The installation of panels requires the use of specialized power tools, i.e., a screwdriver with a special head allowing for proper guidance of the fastener and a screw-in depth limiter. The clamping force of the fastener should be selected in such a way as not to deform the washer.
The acoustic wall sandwich panel PWS2-MWA-ST combines the benefits of mineral wool core panels, led by noise dampening. Thanks to investments in a modern production line, PRUSZYŃSKI has raised the features of this product group to a higher level.
The most important benefits include:
Blachy Pruszyński comprehensively approaches the needs of the market. Thanks to the wide range of lightweight tin buildings and construction products, we are able to respond to any market need – we invite you to familiarize yourself with our suggestions!
In the case of wool layered plates, the designer must take into account the temperature differences between layered panels. Temperature gradients resulting from the temperature difference between external temperature and internal temperature depend on, among others
The table below shows the permissible length of plates depending on the colour of the cladding, assuming a minimum length of 2.5 MB for single -span systems. The maximum length of the plate is 18 MB, but it depends on the color chosen.
