Improve your plant's: Energy performance, noise levels, and brightness. Ideal for new projects or remodeling: Fast installation, minimizes plant downtime, minimizes any weather related delays, and applies to most surfaces including glass.
Thermal performance
The spray application of K-13 eliminates voids, gaps and compressions that occur with prefabricated insulation. This monolithic coating results in K-13's outstanding field performance. K-13 utilizes a patented adhesive system which adheres to virtually any substrate including glass, urethane, Styrofoam, wood, metal and concrete. K-13 can be installed from 3/4 inch to 4 inches without mechanical support. This will provide R values from 3 to over 16.

Independent field tests comparing K-13 and fiberglass batts in buildings of identical construction showed that K-13 sprayed 1 inch thick on 26 gauge metal out-performed 2 inch fiberglass batts. The savings difference between the buildings exceeded 2,400 KWH per month.

K-13 is also an excellent insulator in unconditioned buildings. Field tests demonstrate that 100 degrees outdoor temperatures are reduced to as low as 85degrees at indoor floor level areas. In colder climates, heat generated from operations has often provided enough heat to keep the building comfortable after insulating with K-13. This results in greater worker comfort and increased shelf life of temperature sensitive inventories.
Reduces Noise Levels
K-13 reduces reverberation and noise levels. The result is a more comfortable working environment providing greater utilization of the building.

The type of insulation used in your home will have a significant effect on your home's energy costs. The right time to determine what type of insulation you should have is before construction begins. Celbar out-performs other types of insulation where it counts - in your home. This higher performance will lower your monthly utility expense, reduce wear and tear on your heating and air conditioning unit, and may help qualify you for a higher mortgage by reducing the amount of your monthly expenses.
Celbar is a blend of specially prepared cellulose fibers, organic in nature, treated with adhesive and life resistant chemicals. Sprayed-in-place, the interlocking fibers result in a mass which produces superior sound and thermal properties. The unique application process of Celbar seals cracks and holes in the wallboard, around plumbing and electrical outlets, vent ducts and other irregularities. There are no compressed areas or voids to allow sound leaks, reduce thermal efficiency or promote air infiltration into your home.

Acoustical Insulation: The Sound Solution

In today's busy world, our homes and offices are often threatened by unwanted noise from people, television, audio technology, heating/cooling systems, and communications equipment, transmitted through walls and partitions into our surroundings.

As a result, contemporary building design must keep up with today's increasing sound contro needs without exceeding strict cost restrictions, and it can, with Knauf Fiber Glass Insulation.

How Sound is Measured

Conversation, television, radios, machinery, and traffic all produce sound waves from the other side of the wall, causing audible noise to flow into adjoining areas.

This sound is measured by its power level at various frequencies, typically represented by octave and 1/3 octave bands. The magnitude of the sound's power level for a given bandwidth is measured and expressed in units called decibels (dB's). The higher the dB level, the greater the intensity of the sound being transmitted for the bandwidth being measured.

The human ear is more sensitive to some frequencies than to others. The ear hears a 1000 Hertz (Hz) tone louder than a tone at 200 Hz or 4000 Hz, even though all three tones may have the same CIB level. As a result, many noise control design regulations are weighted to account for increased hearing sensitivity.

The human ear does not perceive sound changes in direct proportion to the change in dB. For example, to perceive a halving or doubling of loudness, the sound pressure must be changed by 10dB. The table below further demonstrates the relationship between sound power level changes and human perception.

Sound Power Level Change Perception

0-3 dB - Barely perceivable
4-5 dB - Perceivable and significant
6 dB - Resultant sound level 1/4 of initial level
7-9 dB - Major perceived reduction
10 dB - Resultant sound level 1/2 of initial level

How to Control Sound

There are three general methods for controlling the path of transmission for sound waves through walls and partitions: adding mass, breaking direct structural paths, and adding absorbing materials to the cavities.

For most common materials, you can significantly control sound transmission by adding mass. Heavy materials usually block sound better than light ones. However, adding mass is not always practical because the increased weight can affect the structural soundness and aesthetic properties of lightweight construction.

Breaking the transmission path by minimizing direct structural contacts through discontinuous construction can also control noise effectively. Double or staggered stud walls and resiliently mounted wall surfaces can significantly reduce the level of sound transmission.

One of the best ways to control sound is to install Knauf Fiber Glass Insulation in the wall cavity. Fiber glass insulation is one of the most cost efficient sound absorbent materials available.

Knauf Fiber Glass installed in the wall cavity can significantly reduce sound transmission from surrounding sources to maintain a quiet, serene working atmosphere.
