Advantages of cellulose fibre


With the rapidly increasing cost of electricity, as well as the ongoing load shedding experienced in recent years, an energy efficient home is one of the primary desires of South African homeowners. Not only does a well-insulated home save you money year-round, it also keeps you comfortable and healthy –improving your lifestyle.

Thermguard insulation is installed in buildings toimprove the comfort levels of the occupants,conserve energy and ultimately slow the burning of fossil fuels, thus reducing greenhouse gas emissions.Although Thermguard does not physically heat or cool your home, it prevents the transfer of heat (or cold) from the outside/inside through the ceiling by up to 92%. Each home is unique, but on average we expect the difference between an un-insulated home and one insulated with Thermguard, to be in the region of 4-6°C.

In summer, the hot African sun beats down on your roof causing the still air in your roof space to reach extreme temperatures, creating an oven effect. This heat is transferred via conductionthrough theceiling making your living space extremely uncomfortable. By installing Thermguard, you willprevent the heat flowing downwards into your cooler home by up to 90%.

During our freezing winter months, Thermguard will keep your home naturally warm by retaining the heat generated during the day inside your living space. Heat sources such as electric or gas heaters,or a fireplace will be unnecessary in most instances,but when used will not need to stay on foras long. You will simply need to generate heat until you are comfortable, then switch off the heat source and let Thermguard retain the heat in your home. When fitted at 135mm, the reduction of heat flow in winter is an amazing 92%.

Recycled Content

Most home owners are unaware of the significant impact their decision of choosing cellulose fibre as their insulation can make on the environment. Thermguard insulation contains the largest amount of recycled contentof any ceiling insulation in the industry. It is manufactured from more than 80% post-consumer recycled newspaper (one of the largest parts of our waste stream) which would otherwise be dumped in landfills, creating greenhouse gasses whilst decomposing.

In addition, using paper to produce cellulose fibre insulation preserves valuable landfill space. In the last year the company has recycled more than 1100 metric tons of post-consumer newspaper. Informal collectors are also able to provide a stable income for their families by selling collected newspapers directly to the factory.

Additives

The non-recycled components of cellulose fibre insulation are still environmentally preferable to raw materials used by most other insulation types as they are non-toxic and 100% natural. These natural salts and minerals are used in agriculture to promote plant health; stop and prevent wet and dry rot in timber; and they also have various uses in the household and medical fields. The borate additives in Thermguard are harmless to humans and pets; however, it will irritate insects and rodents such that they will not live in the material or use it to build a nest. The result is that the Thermguardis apassive, yet effective, pest controlmeasure ensuring a clean and healthy home.

Fire Retardant

The borate treatment also gives Thermguard the fire retardation to meet South Africa’s SANS 428 test criteria and classified B/B1/2, meaning that it does not support flame spread. It will also withstand the heat of a blow torch without melting or emitting noxious fumes. Cellulose has been proven to protect properties against the threat of fire and has even reduced the spread of accidental fires and the resulting damage.

Health Aspects

Cellulose fibre has great advantages forindustrial health and worker safety. The highest health risksoccur during the manufacture,installation, and removal of insulation. None of which is an issue with cellulose fibre.The sole hazard for cellulose is categorised by the American “Occupational Safety and Health Administration” as a dust nuisance. They advise that the only requirement is the use of a simple dust mask during manufacture, installation and removal of cellulose fibre. This compares very favourably to the health risks associated withthe handling offoam products and synthetic fibres such as fibreglass.In addition, most fiberglass and polyurethane insulations use formaldehyde-based glues, which present a continuing hazard during manufacture and evenyearsafter installation due to off-gassing of the formaldehyde.

Embodied Energy

Embodied energy is the energy that is consumed by all processes associated with a product throughout its manufacture, use and deconstruction or decomposition. The embodied energy of cellulose insulation is by far the lowest compared to all other insulation materials commercially available. Furnace-made insulation materials (fibreglass and polyester) require 10 –14 times more energy to produce compared to cellulose fibre, and foam products (polyurethane) contain up to 64 times more embodied energy than cellulose fibre. Cellulose fibre is 100% biodegradable and will not negatively affect ecosystems or wildlife.

Glass and plastic insulations are not accepted by recycling companies because they cannot be recycled and take hundreds, if not thousands,of years to break down into their separate material components. These tiny pieces of material will never return to a natural state, yeta biodegradable product such as cellulose fibrewill. In addition, most landfills do not accept fibreglass waste as it is regarded as hazardous waste.

Approvals and Quality Controls

Thermguard has maintained the prestigious SABS Mark-Permit Number 11176/117526for more than 20 years. In addition to the SABS Mark, Thermguard insulation is manufactured in a factory which complies with the International Organisation for Standardization (ISO) 9001:2015 QualityManagement System requirements, our assurance to you of a consistently high-quality product.

Installation Advantages

When Thermguard is blown onto your ceiling it fills every nook and cranny and gives 100% coverwhich ensures that no heat gains or losses can occur. Cellulose fibre is easily blown over items such as pipes, brandering and wiring, leaving few air pockets that would reduce the overall effectiveness. Downlighters and transformers are protected by covers which isolate them when the insulation is blown onto theceiling, and wiring can easily be traced should maintenance be required. Fewer installers are needed to blow cellulose fibre onto the ceiling than those required for installing rolled insulation. Fewer people in the roof space means there is less chance of damage during the installation. Thermguard is non-toxic and non-irritantand can be moved aside by hand should any maintenance or renovation work be necessary after theinstallation.

A Real World Test

The University of Colorado School of Architecture and Planning conducted a study that compared two identical buildings, one with cellulose fibre and the other with fiberglass insulation. On average, the building fitted with cellulose fibre performed 26% more efficientlythan the building fitted with rolls of insulation. The energy performance increased to 38% more efficient when tested in extreme climates. This efficiency is due to the fact that cellulose fibre is blown into all of the nooks and crannies, effectively sealing off the movement of air.

Acoustic Performance

Noise reduction is achieved in three ways with cellulose:

1. Cellulose fibre completely fills cavities leaving no air pocketsforsound to travel through.

2. Cellulose fibrestrap air, which in turn traps the movement of sound wavesthrough the air.

3. Cellulose fibre is approximately three times denser than fibreglass, meaning that it can absorb sound much more effectively.

Moisture Concerns

Small drip leaks will not harm Thermguard or your ceiling as they will be absorbed by the insulation. When the roof space heats up, the moisture will evaporate out of the insulation, leaving it and your ceiling unharmed. This is why Thermguard is known as a “breathing insulation”. Thermguard is also resistant to mould and fungus.
