Cellulose Insulation

Insulguard Insulation and Total Roof Vacuum
Be Warm in Winter, Cool in Summer
Cellulose Insulation has gained its reputation worldwide as the most environmentally friendly insulation and is fast becoming a popular choice for insulating homes.

For every 1% not covered = 5% loss in insulation effectiveness. With its' loose fill properties - cellulose insulation can provide 100% coverage by insuring no gaps in the installation.

Blown In Cellulose Insulation Is:

• Fire & Pest Resistant
• Manufactured from recycled paper
• Great acoustic properties


In a demonstration experiment testing the difference between Cellulose Insulation and Fiberglass Insulation, Cellulose Insulation reduced an alarm of 125 decibels to 40 decibels. The fiberglass insulation did reduce the noise level as well, but only to 75 decibels.
Cellulose insulation materials fulfill these requirements perfectly. A higher degree of sound-wave absorption correlates to a higher longitudinal flow resistance. The sound wave travelling through the insulation material experiences friction when coming into contact with the fibres which results in a higher resistance level. The sound energy (in the form of air pressure) is thereby transformed into heat energy. The sound energy that is transformed can no longer be heard on the other side.
Blown in cellulose insulation easily flows around obstructions and penetrates odd shaped cavities and it easily conforms around wires, electrical boxes and pipes.

Blown in cellulose insulation is 2-3 times denser than fiberglass insulation.

We specialize in low pitch, Rake, flat and skillion ceilings that are inaccessible to most other insulation types


MUCH HIGHER SOUND DENSITY RATING
Many residential structures contain large amounts of wood. Cellulose insulation is the only wood-based building material that is always treated with fire retardant and is vermin Proof.
Insul-Guard only uses cellulose that has been treated with non-toxic Borax and Boric acid that is manufactured in our own factory to Australian standards this makes cellulose insulation one of the safest materials used in home construction.

If a fire occurs, the dense structure of cellulose and its fire retardants slow its spread through the building by blocking flames and hot gases and restricting the availability of oxygen in insulated ceilings. Air and fire roar right through fiberglass. This is due to the most flammable tar used on the paper vapor barrier and the low density of fiberglass batts which doesn’t block air movement. Several fire demonstrations have been conducted in which cellulose-insulated structures have remained virtually intact while uninsulated and mineral-fiber insulated structures burned to the ground.

1. Cellulose is the oldest building insulation material. Many types of cellulosic materials have been used, including newspaper, cardboard, cotton, straw, sawdust, hemp and corncob. Monticello was insulated with a form of cellulose. Modern cellulose insulation, made with recycled newspaper using grinding and dust removing machines and adding a fire retardant, began in the 1950s and came into general use in the US during the 1970s.

2. The market for insulation increased following the oil embargo of 1973-74. The embargo caused energy costs for heating to skyrocket across the nation, which led to increased interest in energy conservation measures. Insulation gained significant national attention as a cheap and available technology to increase the energy efficiency of homes. In 1977, following a particularly severe winter, a tax credit was given for homeowners who installed insulation.

3. While in 1976 there were roughly 100 cellulose insulation firms with 125 plants, by 1978 there were more than 350 firms with more than 500 plants1. Cellulose insulation was produced locally by small manufacturers who purchased ready-to-operate machines and offered a cheap and easy low-tech production process. Other than some constraints created by a shortage of boric acid for use as fire retardant, cellulose captured an increased share of the market due to lower costs and its suitability for retrofits. Meanwhile fiberglass and rockwool producers found it difficult to keep up with the demand for insulation from their customers.

Currently cellulose insulation has increased again in use in the United States. Part of the reason for this growth are studies that suggest that cellulose may actually protect a building from damage in a fire better than fiberglass because cellulose is denser than fiberglass and doesn't allow the oxygen necessary to burn structural members. Several National Research Council Canada studies [2] have backed these claims. Another major reason for the comeback of cellulose might be because of the increased interest in green building. Cellulose has the highest recycled content of any insulation material and also has less embodied energy than fiberglass and other furnace produced mineral insulations.

The thermal performance of loose filled cellulose compares favorably to other types of insulation. The thermal conductivity of loose-fill cellulose is approximately 40 mW/m•K (an R-value of 3.8 per inch) which is about the same as or slightly better than glass wool or rock wool. This doesn’t represent the whole picture of thermal performance. Other important aspects are how well the building envelope is sealed from air infiltration, convective airflows, and thermal bridging.Cellulose is very good at fitting around items in walls like pipes and wiring, leaving few air pockets that can reduce the overall efficiency of the wall

SOUND INSULATION

Noise reduction is achieved in three ways with cellulose. The first is that cellulose completely fills cavities leaving few air pockets for sound to travel in. The second is the cellulose material's ability to trap air. The significant difference between noise reduction with cellulose and fiberglass is its density. Cellulose is approximately three times denser then fiberglass. This helps deaden the sound through walls and between floor levels.

FIRE RETARDATION

The borate treatment also gives cellulose the highest (Class I) fire safety rating.

RECYCLED CONTENT


Cellulose is composed of 75-85% recycled paper fiber, usually post-consumer waste newsprint. The other 15% is a fire retardant such as boric acid or ammonium sulphate. Cellulose has the highest recycled content of any insulation available. For example, fiberglass has a maximum amount of 30% recycled content.

The non-recycled components of cellulose insulation are still environmentally preferable to the raw materials of most other insulation types. Unlike foam insulations, many of which use HFC or HCFC blowing agents which have global warming potential hundred or thousands of times higher than that of carbon dioxide, cellulose does not produce significant gaseous emissions.

Cellulose has great advantages for industrial health and worker safety. Toxicity of the raw materials of most insulation types is typically highest during manufacture or installation. Neither is an issue with cellulose.

The sole hazard of cellulose according to the categorization by the OSHA is that it is a dust nuisance, requiring a simple dust mask during installation. This compares very favorably to the potential NIOSH cancer risk of fiberglass Embodied energy

WHAT DOES “R-VALUE” MEAN?

R-value is a measure of resistance to heat flow through a given thickness of material. In theory, the higher the R-value, the greater that resistance. That’s fine as far as it goes.

Unfortunately, R-Value has taken hold in the consumer’s mind as a universal method for comparing insulations - the higher the R-Value, the better the insulation, end of story. But all R-Values are not created equal, because they measure only one of the factors that determine how insulation will perform in the real world.

Insulation is, first and foremost, meant to stop the movement of heat. The problem with using R-Value as the sole yardstick of an insulation’s effectiveness is that heat moves in and out of your home or commercial building in four ways: by conduction (which R-Value measures), and by convection, radiation and air infiltration (none of which R-Value measures). But let’s stick with the concept of R-Value for the moment.

The R-Values of insulation materials are measured in a lab. That would work great - if your home were inside a lab! But your home was built outdoors, and that means there are other factors like wind, humidity, and temperature changes in play. These factors create pressure differences between the interior and the exterior of the building due to things like hot air rising, wind, and mechanical systems forcing air through every tiny little opening and making its way to the interior or exterior, or to unconditioned areas of the building like attics, basements and crawl spaces.

Your home or commercial building may look solid, but there are thousands of tiny gaps, cracks and penetrations between building materials. For example, if you apply the air pressure of a 20 MPH wind on a 20 deg. F day to a building, the typical R-19, fiberglass insulated wall often performs no better than the wood studs (R-6) because of air infiltration, with heat being transported around (bypassing) the fiberglass batts through convection. In very low density materials like loose blown fiberglass, heat will actually radiate right through the insulation, and this, along with convection, significantly reduces fiberglass' installed performance and your comfort.

A superior insulation system will have good R-Value (prevent heat loss via conduction), will be pneumatically or spray applied, fully filling the building cavity (prevent heat loss via convection), and will be densely packed (prevent heat loss via air infiltration and radiation). Fiberglass meets the first criteria, but not the other three. Cellulose meets all four of these critical performance criteria!

In addition, you want your insulation to do more than just insulate. Besides insulating, cellulose can help prevent the spread of flames in the event of a fire and blocks the transmission of sound much more effectively than fiberglass. The insulation in your walls, ceilings, attic, etc., has a lot of jobs to do besides insulating - and cellulose is up to all those jobs!


INSULATION AND THE ENVIRONMENT

While people may debate the causes of global warming, it is just common sense to use products that have as little impact on the environment as possible.

Insulation, by reducing the amount of energy required to heat or cool a building, is environmentally friendly. But don’t be fooled into thinking all insulating materials are equal. There is plenty of greenwashing taking place to make products look more beneficial, or less harmful, to the environment than they really are.


OTHER FACTS ABOUT CELLULOSE INSULATION

Dispelling the myths about mold, fire risk and other key factors of Cellulose Insulation.

Myth:Cellulose insulation settles resulting in loss of original R-Value.

Fact:All loose-fill insulation products can settle over time. By federal law and industry standards compensation for settlement is built into cellulose insulation coverage charts. When installed properly in accordance with the coverage chart, cellulose insulation will not settle below the intended R-Value.

Myth:Cellulose insulation is more flammable than other products because it's made from paper.

Fact:Cellulose Insulation has a Class 1 Fire rating. It is treated with fire retardants to meet all federal, state, and local fire safety requirements. Some manufacturers have even qualified two and three hour firewall designs using Cellulose Insulation.

Myth:Damp spray Cellulose Insulation is applied wet in walls increasing the likelihood of mold & mildew.

Fact:This type of application is common in new construction where a small amount of water is added for increased bonding to the sheathing. The moisture content, when installed correctly, dissipates quickly, typically resulting in moisture content at or below wood framing members. Any trace moisture in the insulation will pass through the drywall after it is installed, similar to moisture in wood wall studs.

Myth:Cellulose insulation is more expensive.

Fact:Cellulose Insulation in walls will typically be more expensive than fiberglass batts due to higher installation costs. The difference is easily overcompensated in the greater savings on energy costs by using Cellulose Insulation. Blown in Cellulose and blown in fiberglass insulations are comparably priced. Cellulose Insulation is less expensive than foam.

Myth:Cellulose is made of paper so it will be more susceptible to humidity and mold.

Fact:This is simply not true. Cellulose Insulation is no more subject to mold contamination than any other building material. Published studies indicate that the hygroscopic nature of cellulose insulation results in superior moisture handling characteristics.

Myth:R-Value is R-Value so it really doesn't matter what insulation is used.

Fact:R-Value is only one factor to consider when choosing insulation. The performance of an insulation material is also dependent upon reducing heat loss through air infiltration, convection and radiation. Cellulose Insulation reduces air infiltration and convection better than other fiber insulation products with the same R-Value, giving Cellulose Insulation superior overall performance.

Myth:Cellulose Insulation results in deforestation because it uses wood from trees.

Fact:Cellulose Insulation is made from recycled paper, not material from newly cut trees. In fact, Cellulose Insulation, with almost 85% recycled paper content, actually diverts almost a million tons of waste paper from landfills annually
