Colinwell Acoustic Blocks EC140
Colinwell Acoustic Blocks EC140
Concrete cellular facing blocks with resonating cavity sound cancellation, excellent absorption of low frequency and good absorption of mid and high frequency sound reverberation.
Application
Part of wall construction. Particularly suitable for use in sports halls, swimming pools, gymnasiums, public halls and lecture theatres. Also loading bays, anaerobic digesters, plant rooms, factories, external road and railway/ road sound barriers, bus stations, train stations, road and rail tunnels.
Description
High performance acoustic block.
Concrete cellular facing blocks with enhanced acoustic properties; sound reverberation cancellation is based on the Helmholtz resonator principle. They have been specifically designed to reduce noise reverberation in both internal and external applications, giving acoustic clarity to speech and reducing noise levels of machinery, plant rooms, transport loading yards and sports hall noise. The product manufacturer has ISO 9001 and ISO 14001 accreditation.
Features and benefits:
- Benefits from twin Helmholtz resonators for enhanced acoustic performance, even at low frequency.
- CE-marked and manufactured in accordance with BS EN 771-3, BS 5628-1.
Finish:
Paint grade.
Options:
Colinwell Standard Blocks and Acousta Tex Blocks:
Available in the same sizes and colour options and can be used in conjunction with EchoCheck blocks for continuity of finish. Acousta Tex blocks have enhanced acoustic properties at higher sound frequencies due to a specific textured finish.
Consult Oscar Acoustics for the acoustic properties of Acousta Tex blocks.
