6mm Self-Adhesive bituminous membrane for low frequency acoustic insulation.
Bituminous sheet reinforced with mineral fillers, coated on one side with a self-adhesive mastic finished with an anti-adherent film and on the other side with a high-density polyethylene film. Acoustically it functions as a plastic element between rigid elements, being an effective substitute for lead; between spring elements it functions as a membrane resonator (typical absorber at low frequencies).
Scope
- It is used in industrial insulation as an anti-resonant material, providing acoustic mass to galvanised steel sheets.
- It is used between rigid elements, such as gypsum plasterboard, to improve low-frequency insulation in both vertical and horizontal walls.
- Used between spring elements to increase the overall isolation of the treatment, improving significantly at low frequencies.
Advantages & Benefits
- By adhering to galvanised steel sheets, it improves the resonance of the sheet.
- By increasing the insulation at low frequencies, cavaties used can be kept to a minimal size.
- By increasing the mass of lightweight walls, a higher acoustic performance is achieved.
- It shifts the resonance frequencies of the rigid elements making the insulation stronger.
- Between insulators, it transforms acoustic energy into dynamics, improving insulation at low frequencies.
- Easy to install by stapling to the surface or using M.A.D. Self-adhesive.
