Armstrong Ceilings Perla OP dB is a premium ceiling tile combining the two criterias of acoustic performance taking it to new heights.
The new Perla OP dB 40mm mineral tile combines the high sound absorption of Armstrong’s OP range with the high sound attenuation of its dB range for ultimate acoustic flexibility.
Its launch is designed to help specifiers particularly in the education sector to reduce the amount of sound transferred from traffic routes to learning areas and also to reduce the noise of rain on lightweight roof constructions, an issue also encountered in the office sector. In this area, using the Perla OP dB tile shows a 20dB improvement compared to roof-only construction
Therefore it’s recommended to use in an open-plan and closed-plan space where acoustics cannot be compromised, and in particular for spaces such as music rooms, corridors and classrooms, and individual offices and meeting rooms next to open spaces.
Performing to sound absorption Class A (aw = 0.90), sound attenuation Dnfw 40 dB and sound reduction (single-pass) Rw 20 dB, the Perla OP dB tile can be mixed with Perla, Perla OP 0.95, Perla OP 1.00 and Perla dB tiles to solve specific acoustic requirements while maintaining the same visual.
In addition, the stylish, contemporary Perla OP dB tile provides high light reflectance of 85%, reducing the number of artificial lighting units required, as well as ultra-low VOC emissions for excellent indoor air quality, ISO 5 cleanroom classification and humidity resistance to 95%.
Also featuring the MicroLook 90 edge detail for improved durability, fit and visual, the Perla OP dB range is available with a 30-year system warranty when installed with Armstrong suspension systems.
