Already in use in America and Europe, Wet Spray Cellulose Wall Insulation from Planet Green Insulation is an ideal way to insulate walls both thermally and acoustically to improve the energy efficiency of a building.

Wet Spray Cellulose Wall Insulation delivers both a higher R-Value and STC Acoustic Rating in one application, and can be applied to almost any surface and location, be it under-floor, ceilings, pipes or machinery.

Planet Green Solutions, a company founded on sustainable principles, specialise in cost effective ways to achieve 5-star Energy Ratings for residential and commercial buildings, and recommend using Wet Spray Cellulose Wall Insulation whenever insulation is concerned.

“There is no other product on the market quite like it,” says Simon Shannon, Director of Planet Green.

"For us wet spray ticks all the boxes because it not only does it deliver both thermally and acoustically, but it will also come in at roughly the same price as your regular batt, if not cheaper,” he adds.
One of the more notable differences Mr Shannon points to when selling the Wet Spray Cellulose Wall Insulation onto his clients is its 'no gaps' finish, which is very difficult to achieve with traditional wall batt insulation.

“Clients can virtually see the difference, so when you tell them that they are assured of no air-gaps or leakages, the evidence is there. The end finish is complete. No gaps means no noise, no gaps means no moisture, no gaps means a better insulator,” says Shannon.

One key reason why Wet Spray Cellulose Wall Insulation is making such ground in Australia is its ability to compete on cost, an attribute put down to the simple way in which cellulose can be installed. With wet spray it is in and out, with no fuss.

Cellulose insulation is also widely regarded as one of the most green 'Green' products on the market. Not only is it made entirely from recycled paper pulp, but it also contains less embodied energy than other products. It requires 20 to 40 times more energy to produce furnace-made insulation materials such as fiberglass.

At present the majority of cellulose used in Australia is manufactured in Australia, and unlike fibreglass, cellulose wall insulation contains no binding agents, such as formaldehyde, or chemical enhancements, such as HFC or HCFC, as used in the blowing agent of foam spray.

Furthermore, natural borates added to cellulose in production give it a Class 1 Fire Rating, while making it an effective repellent against insects and rodents. This boric additive is no more dangerious than table salt, with the only real safety concern being a gassing off from the newspapers ink, however when sealed behind walls, the product is entirely safe.

Weighing everything up its easy to see why, in a world where star ratings are becoming an essential selling tool for all buildings, materials such as Wet Spray Cellulose Wall Insulation will become more sought after.
