What is Cellulose Insulation

Thermguard Cellulose Fibre Insulation Overview

Manufacturing Thermguard Insulation uses an amazing 80% recycled newsprint, which is one of the largest parts of our waste stream. This waste is otherwise discarded in landfills thereby creating greenhouse gasses. It is extremely environmentally friendly, has no harmful synthetic additives and is 100% organic and biodegradable. The embodied energy (energy used to manufacture Thermguard) is 15 times lower than glass-fibre based insulation materials and almost 33 times lower than polyurethane (plastic) based insulation materials.


Thermguard ceiling insulation provides a 100% seamless cover as it is pneumatically blown into the ceiling and is a dry product. It offers a greater performance value (R-Value) than all other bulk insulation materials on the market. Its loose fill ensures it reaches all tight corners and hard to reach nooks and crannies within the roof space. These hard to reach areas are more prevalent in low pitched or complicated roofs. As a result, no gaps are left for unwanted air leakage or draughts through the ceiling.

Cellulose Advantages

Insect and Rodent Repellant

100% Seamless Cover

Superior Comfort

  • Additives within thermguard will discourage rodents and insects from living in your roof unlike traditional insulations such as fibreglass or polyester that actually encourage rats to flourish in your roof thus posing a health risk to your family. The additives are of such a low dosage they are not a danger to children or pets, to be concerned is negligible.
  • The most noteworthy advantages over roll type insulation materials is that Thermguard is machine blown dry into your ceiling providing 100% coverage. Thermguard insulation material acts as a fluid, hence covering your ceilings structure completely. This “seamless blanket” prevents any heat gains and losses from occurring through gaps, obstacles and hard to reach places. These inefficiencies would otherwise reduce the insulation materials effectiveness by up to 30%, common problems with blanket insulation.
  • The full effect of Thermguard ceiling insulation will be apparent within 24 hours from installation. Homeowners will notice the living space become more comfortable resulting in less money wasted on heating and cooling. Good roof insulation such as Thermguard will pay for itself within 2-3 years from installation with continued savings to follow.
  • Our insulation will not cause any irritation to allergy sufferers. Unlike fibreglass insulation that is known for its terrible allergic reactions upon the skin, lungs and eyes, thermguard has no effect on the body.

Non – Allergenic

  • Our product is treated with fire retardant additives. Compared with traditional insulations, which melt and emit highly toxic gases when burnt, thermguard will only char and not hold a flame. Consequently, it will withstand the heat of a gas flame torch without melting or emitting toxic fumes. Fire tested to SANS 428 and classified B/B1/2; Thermguard ceiling insulation has been proven to protect properties against the threat of fire. It also has the ability to reduce the spread of accidental fires.

Fire Retardant

Sound Proof

  • Cellulose Fibre based insulation materials have especially efficient soundproofing properties. The acoustic properties of thermguard roof insulation are most accurately demonstrated in the fact that the density is four times that of glass fibre based insulation materials. Hence, once installed, the living space will be sheltered from external noises such as road and airplane noise. Room to room noise within the property is also drastically reduced. Thermguard ceiling insulation will reduce the transmission of sound by up to 45 decibels.


  • Competitively price, Thermguard is an affordable insulation with far reaching advantages in summer and winter.
