BASWA Acoustic Plaster Standard Install Details

Acoustic Plaster Ceiling Details

What are the factors that determine the design of a building during the planning phase? Besides its elementary functions, such as protection from environmental impact, the building creates boundaries against the exterior, but also against the interior: it provides information about the prominence of the builder, its inhabitants and users. However, as a rule, besides information, the building is supposed to provide its direct and indirect users with a sense of wellbeing.

Increasingly complex and more sophisticated building technology has a continuously growing influence on the design of structures.  Especially the mandate to build structures that sustainable from an energetic perspective gives rise to its own visual syntax. The creation of the acoustic climate in the room plays a role in this context as well.

Aesthetic and functional specifications are frequently in conflict with each other and compel the architect to give priority to one of these aspects. Consequently, it is enormously beneficial if technologies and materials have the capability of accommodating both aspects. BASWA systems offer a concept that does not impose its own rules upon users and planners and that does not hamper their design flexibility.

Each system is available in the following four system thicknesses: 30 / 40 / 50 / 70 mm.
All systems can be applied directly to concrete or conventional drywall systems (mineral substrates).

The glued and grouted BASWA Phon acoustic panels can be coated with either one or two layers of microporous acoustic plaster. The following surface structures are available:

  • BASWA Base

  • BASWA Fine

  • BASWA Top

Roughest surface structure (Grain 0,7 mm) Average surface structure (Grain 0,5 mm) Finest surface structure (Grain 0,3 mm)

BASWA Phon acoustic systems can be designed as single-layer or two-layer systems (“Classic”). BASWA Top can only be used as a two-layer system “CLASSIC Top”.

BASWA Access Hatches

BASWA Access Panel

The BASWA inspection opening flaps are individually height-adjustable and already RAL9010 PUR-coated. A special breathable acoustic inlay in the door frame pre- vents the surfaces from ageing differently. It is important that the side connection between the outer frame and the substrate is sealed airtight beforehand. This prevents air from flowing through the adjacent acoustic system.

In addition, the commercially available height-adjustable products, which must be powder-coated beforehand, can also be used. The lid is coated with the primer and top coat and thus initially receives the same surface as the ceiling. To prevent different ageing of the surfaces, the lid can be fitted with a breathable acoustic inlay from BASWA. (Include inlay thickness 16 mm plus 2 mm coating.)

BASWA Alumium L Profile

L-angle profiles made of chromium steel, burn-in painted sheet metal, plastic or powder-coated aluminum can also be used for edge formation.


The L-brackets must be aligned to the required system thicknesses (30, 40, 50, 70 mm). This application provides protection against mechanical damage. With angle profiles that are exposed to heat radiation, there is a risk of cracking between the profile and the acoustic plaster. (Note coefficient of expansion aluminum, PVC or steel!)

BASWA Installation Platform

Board
BASWA Installtion Platform

The BASWA IP is used for the partial installation of built-in elements with expan- sion springs, which require low construction thicknesses for fastening. The pressure-resistant nature of the IP prevents the edge of the ceiling cut-out from breaking out and reduces the need for wide cover rings.

The BASWA IP is based on a pressure-resistant, open-pored panel. The installation platform is calibrated to the respective thickness of the BASWA Phon acoustic panel and is available with or without opening cut-out.

200 mm x 200 mm for d < 140 mm
300 mm x 300 mm for 90 mm < d > 220 mm Other dimensions are available on request.

They are glued to the respective substrate, screwed mechanically as required and sealed airtight all around. The acoustic panels are then fully connected to the installation platform, the joints and screw holes are filled with BASWA Fill and ground at the same level.
