SOUNDLINE-ACUSTICA Point Block 4PC
SOUNDLINE-ACUSTICA Point Block 4PC
PPGZ slabs with Point Block perforation. Mounted on a frame, they are effective sound-absorbing structures with a resonant structure. The distance between the slabs and the hard surface is essential for the low-frequency sound absorption. Sound-absorbing properties over a wider frequency range are enhanced by additional placement of Shumanet slabs in the space between the hard surface and the cladding.
Scope of application
- office and administrative buildings
- hotels, halls, meeting rooms, restaurants
- schools and kindergartens, auditoriums, offices
- medical institutions and hospitals and other premises with special acoustic requirements
Compound
Gypsum board, flame-retardant, sound-permeable black fiberglass, water-based adhesive.
Perforation coefficient: 12.9%.
Point perforation is available in both solid and block versions.
Distinctive features:
- Seamless design
- Increased sound absorption when installed with offset and filled with acoustic mineral wool
- Eco-friendly material, stabilizes indoor humidity
- Convenient installation, easy repair
- Painting in any color after installation
