Caice Acoustic Louvres
For more than 20 years Caice have been
combining our acoustic expertise with
precision UK based manufacturing to deliver
high performing product solutions for our
clients.
The Acoustic Louvre product with single bank and
chevron variants is an integral part of our
environmental noise control portfolio; designed to
meet the most stringent noise criteria requirements.
All Acoustic Louvre products are selected to meet a
client’s specific needs and are suitable for a range of
applications including: fresh air intakes for ventilation
systems, mechanical equipment screens and noise
barriers.
Rest assured that high performance doesn’t mean a
compromise on aesthetics. Our Continuous Line
product design means that concealed joins and
corners provide a seamless look to a screen or
enclosure. Combining this with a range of material,
paint and treatment options, the finished product can
be as individual as a specific project requires. Recent installations at Premier Inn, Tenby
and Project Dragonfly, Kent
