What is the Envirospray 300?

ENVIROSPRAY 300 (E300) is an all Australian acoustic insulation and thermal spray applied coating that may be installed to any stable substrate. Typically, E300 would be applied to the underside of concrete slabs, metal roofs, plasterboard / gypsum board ceilings / timber floors.

ENVIROSPRAY 300 is manufactured to strict quality guidelines in Australia and Thailand and shipped worldwide in 12 kg PE bags to global sites – primarily in South East Asia / UAE / India / Australia. On site, E300 is blend mixed in a 2-part spray gun, under high pneumatic pressure, with formulated PVA and sprayed up to 100mm thick, to the underside of concrete slabs, roofs, walls & ceilings – as a final visual finish, which is monolithic in nature and a plush pile carpet like texture.

ENVIROSPRAY 300 is a natural insulation made from natural cellulose fibres and has 80% recycled content and ultra-low VOC. E300 insulation system is manufactured in two virgin colours – “Steel Grey” & “Off White”. Both colours may be dyed on site to obtain specific hues – the most popular being Jet Black & Charcoal.

ENVIROSPRAY 300 has been tested and proven for compliant Fire Performance / Acoustic Performance / Thermal Performance to AS / NZ / BS / ISO / ASTM Standards.

When & Where is Envirospray 300 Used?

Envirospray 300 (E300) has exceptional acoustic and thermal insulation properties that is best used to achieve the following outcomes:

OUTSTANDING REVERBERATION CONTROL
E300 is used within spaces with excessive reflective surfaces and/or excessive noise sources to obtain overall ambient noise reduction via reverberation time (Rt) reduction. The utilization of E300 for this purpose is one of the most cost effective in the world, especially suited for large area applications such as stadiums, basketball courts, theatres, cinema baffle walls and open plan offices.
EXTREME RAIN NOISE ATTENUATION
When E300 is sprayed to the underside of metal roofs, the resultant “stiffening” of the sheeting achieves outstanding rain noise dampening.
HIGH TRANSMISSION LOSS WALLS & ROOFS
Often E300 is used in conjunction with plasterboard / metal sheet / gypsum board, wall and ceiling assemblies to obtain enhanced STC/Rw rating up to NATA Tested Systems of Rw 80.
ENERGY EFFICIENT THERMAL BARRIERS
E300 has a high thermal restivity equivalent to glass wool and can be spray applied around existing services & fixtures to obtain thermal barriers and sound proofing with no thermal bridging or leaks.

How is Envirospray 300 Installed?

In Australia & New Zealand, ENVIROSPRAY 300 is offered & installed by Enviro Acoustics Pty Ltd only.

The thickness, location, texture and dry density of Envirospray 300 (E300) are the parameters that determine the final Acoustic / Thermal Performance. These Specs are generally pre-defined by Project Consultants or we can offer informal advice based on 25 years of solid experience.

Installation of E300 involves the use of a 3-man crew operating a specialized fibre spraying unit alongside high pressure PVA pumps that blend the E300 mixture just before spray application.

All unsprayed items are generally masked out with plastic / masking tape while heavy duty plastic is laid on the floor to protect the same. As E300 is non toxic and has no odour, no special precautionary steps are required except for guarding against nuisance dust.

The skill of the spray installer is vital to achieve a uniform pleasing flat look that will endure and perform for years.

In India ENVIROSPRAY 300, is installed by Envirospray (Ind) Co Ltd.
In UAE/Kuwait /Qatar/Oman, ENVIROSPRAY 300 is installed by Enviro Acoustics FZE.
