Seamless Protection

Unlike common batt insulations, GreenFiber Cocoon Insulation is sprayed into walls and cavities, creating a continuous blanket of protection from energy leaks. This monolithic blanket, combined with GreenFiber Cocoon Insulation's high R-value, enhance the energy efficiency of the home.

Studies of actual buildings show that cellulose-insulated buildings use as much as 26% less energy than similar buildings insulated with typically installed fiberglass at the same R-value. One reason for this is the ability of cellulose to control air infiltration.

Uncontrolled air leakage through exterior walls and ceilings is almost as important as R-value in determining how much energy will be required to heat and cool a building. GreenFiber Cocoon Insulation is very effective at greatly reducing air infiltration; it fills cavities and around obstructions filling cracks and seams.
Install GreenFiber Cocoon Insulation for Effective Insulation throughout Your Structure

The building envelope plays many roles in the proper function of the entire structure. It serves as the thermal barrier and the air pressure barrier of the building. The systems approach to design and construction ensures that GreenFiber Cocoon Insulation will perform to meet a wide range of structural demands.

Construction and workmanship are critical to building envelope performance. The examples below illustrate effective installation techniques for addressing varying conditions, from foundation to attic.

High R-value

GreenFiber Cocoon Insulation is manufactured in specially designed mills that separate cellulose fibers. This technique produces less dust and the fibers are more uniform in size to provide the maximum possible R-value. These fibers remain uniform, so they won't lose their ability to block air movement through the years.

GreenFiber also maintains R-value even under extreme cold conditions. The insulation's seamless monolithic blanket ensures that R-values are not compromised. The R-value and density of GreenFiber Cocoon Insulation reduce air flow and help homeowners realize energy savings.*

*Savings vary. Find out why in the seller's fact sheet on R-values. Higher R-values mean greater insulating power.

Achieve Full Insulating Potential with the Systems Approach to Design and Installation

Modern buildings consist of thousands of components that shape large functional interrelated systems. When all the components of these systems work together, the results are dramatic: maximum safety, durability, comfort and efficiency throughout the structure.

That's the systems approach to building design. And it is the approach that can help you achieve thermal performance and insulation value with GreenFiber Cocoon Insulation.

Effective Thermal Installation

Insulation plays a crucial role in the building envelope system. It is important that insulation be in direct contact with the pressure barrier. The pressure barrier is the plane commonly made of drywall that separates the conditioned area of a building from the unconditioned area. Adherence to these guidelines will produce an effective thermal boundary:

No Gaps

Gaps commonly occur in the thermal boundary when insulation covers too short or too narrow an area for a stud cavity.

No Voids

Holes in the thermal boundary allow unwanted heat gain during the summer and heat loss during the winter. Typical problem areas are knee walls, stairs on exterior walls, vaulted ceilings, tubs or tub and shower stalls, and utility shafts.

No Compression

Insulation achieves its full R-value only when it is allowed to remain at its full thickness.

No Misalignment

Misalignment occurs when there is a separation between the insulation and the air barrier. This space allows air to circulate inside or through the cavity resulting in a decrease in insulation performance.

No Wind Intrusion

In attics, wind can enter the insulation through soffit vents and reduce R-value. Therefore, wind baffles properly installed prior to insulating can prevent wind intrusion.
