D-ACOUSTI – LITE is a flexible, open-celled polyurethane acoustic foam engineered for superior sound absorption and high fire resistance. Classified to EN 13501 B-s1,d0, BS476 Class 0, and UL94 V-O standards, it is chemically inert, non-dusting, and easy to shape or apply to complex surfaces.
Available in rolls or sheets with optional self-adhesive backing, d-acousti-lite is widely used across HVAC, marine, OEM, and construction industries for applications such as duct lining, acoustic enclosures, sound panels, and room treatments.
