With its great thermal insulation,acoustic performance and excellent environmental protection feature, Ecocell spray cellulose fibers drive the formation of organic fiber industry.This product is made from recyclable natural timber through special processing to form green environmental protection building materials and do not contain asbestos, glass fiber and other synthetic mineral fiber. It has the property of fire prevention, mildew proof and insect-resistance after special treatment.
Ecocell spray cellulose fiber is carried out by the technical construction workers with special spray equipment for the construction, it can not only combine with the special adhesives, spray onto any building at the grass-roots, with an effect of insulation sound-absorbing effect, but also can be separately poured into the wall cavity, forming a tight insulation soundproof system.


1、Soundproof and noise reducing：
Natural fibers are with porous structure.They can absorb sound energy effectively, reduce and eliminate noise and can be sprayed on the underlying surface of the building directly, but don’t affect the original configuration space. Cellulose fiber’s Noise Reduction on coefficient (NRC),testing by the state authorities,is as high as 0.85, well above other types of acoustic materials.The following is the specific parameters of sound absorption performance:

After spaying perfusion, cellulose fibers material become close and fill hole effectively causing by pipeline installation, thus prevent the infiltration of sound.Together with wall coverings, seamless coating system,it can form a good building insulation system.Here are several kinds of wall material and their corresponding on STC (sound insulation level) values:

The wall type	STC
No sound insulation materials	31
2.5 inches (63.5mm ) thick sound insulation cotton	33
38.1mm thick Ecocell spraying cellulose fiber	49
88.7 mm thick Ecocell spraying cellulose fiber	51

[ the wall type: double -side 0.5 inch gypsum board wall (with a 2.5 inch metal bolt) ]

2、Heat insulation:
Cellulose fiber’s thermal resistance up to 3.7R/in, coefficient of thermal conductivity is 0.0039 w/m k, With spray construction, it forms a compact structure after construction, prevents air convection, forming excellent insulating performance and achieving the goal of building energy efficiency.

3、Fire retardant：
Through special processing, it has very good effect on flame retardant.Effective seal can prevent air combustion, reduce the rate of combustion and increase the rescue time. And fire prevention performance will not decay with time, the longest time can up to 300 years.

4、Insect-proofing and fungi-proofing：
Through special processing, it can prevent the attack and reproduction of cockroaches, ants, and other pests.The product itself is moisture-proof and doesn’t provide wet environment to the mold to prevent the reproduction of mold and diseases, because the mold is often the root of many diseases. With the insect-proof performance persistence, insects cannot produce immunity, it’s safe and has non-toxic side effects on people and pets. Therefore, it can not only protect the wall and indoor environment,but also provide the residents a healthy living environment. It has quite ideal effect of pest control.

5、Health and safety：
100% natural cellulose fiber, doesn’t contain silicate cotton or glass fiber.It’s non-toxic and non-irritant and does not irritate skin and respiratory tract. With high safety index, it can not only guarantee the health of residents, but also ensure the worker’s health. Here’s comparison of LD 50 value between Ecocell spray cellulose fiber and other substances in their daily contact.

Product name	LD50（mg/kg body wt.）
nicotine	50
caffeine	192
salt	3,000
Ecocell	19,879
sugar	25,800

It can be seen that the health security of the Ecocell even 6 times higher than table salt.

6、Convenient installation：
Ecocell spray cellulose fiber is worked by special machine and equipment for spraying construction. Usually, a device only need 2-3 workers, 300-500 square meters of spraying operations on average can be completed a day, depending on the site construction conditions. Ecocell spray cellulose fiber cost less working hours than other similar material and can save the cost indirectly.
