ACOUSTIC CURTAINS
We design the Acoustic Curtains to provide a degree of sound absorption within the space in which they are
used. Noise levels can be typically reduced by as much as 20 dB(A) with a properly designed curtain
enclosure Often used in performing arts spaces they not only provide a variable acoustic environment for
different applications but control excessive reverberation in halls with very reflective surfaces.
All material is chemically treated to create a DFR (Durably Flame Retardant) fabric that will withstand a number of dry cleanings. This meets the requirements of BS5867: Part 2: B which is the British Standard for flame retardant fabrics used for the manufacture of curtains.
The degree of sound absorption depends on the weight of the fabric used, the depth between the curtain and the wall and the degree of pleating.
We have three grades:
Linings
Standard units are supplied unlined but lining options are available.
Fullness
Standard units are supplied to 50% fullness. This means the degree of pleating. At 50% this means the curtains are one and a half times the width of the track.

FLOATING FLOOR
The floating floor, ceiling or wall refers to the technique used for the installation of each and does not
necessarily mean that the structure is separate. A floating floor, wall or ceiling is a great way of
isolating vibration. These floating structures are designed by EnvirotechSystems using a 25mm vibration pad
with a 40 mm protection layer. This is further reinforced using concrete. A plywood floating floor can
reduce sound reverberation upto 18dB(A).
The floating floor, ceiling or walls could be tiles or panels. The client has a wide choice of veneer in each section. The most common and popular choice is a wooden finish. Floating panels are frequently used for performance halls and other related activity including recording studios where the quality of sound is of utmost important. The floating floor, walls and ceiling tiles are non-corrosive, termite resistant, moisture resistant, non-toxic and does not degrade with age. It looks as fresh and new even after a long period of time. One can also place a carpet directly over a floating floor surface without any hassle.
A floating floor can be installed in any location including residences, hotels, schools, hospitals, commercial buildings and even noise sensitive areas like studios and rehearsal rooms. Places where there are loud noises like in industrial workshops and dance clubs, they can use a floating floor to prevent the sound from carrying through to the floor below. A floating floor inhibits the sound from passing through to the floor below. This could also prevent the noise of common movement like footsteps or for kids jumping and thumping from being heard or felt in the floor below.
