EW687D InstaCoustic AC90/25FP Acoustic Ceiling System


This is an assessment of the InstaCoustic AC90/25FP similar to the LABC approved AC90/2FP. It is an adjustable acoustic ceiling system for a timber floor that provides an enhanced acoustic performance, however this version has the inclusion of the 25 kg/m² sound barrier tile and is intended for refurbishment projects without the additional use of an overlay system above the timber floor.

This results in providing maximum acoustic performance where there is no possible access to the property above.

The system can be installed at depths ranging from 75mm to 1.5m.
