Frequently Asked Questions

  • If THERMGUARD is made from recycled newsprint, surely it will burn?

    THERMGUARD is treated with a number of fire retardent additives and thus it will not burn. It is fire tested under SANS 428 and is classified B/B1/2. The additives will last the lifetime of the building.

  • Will THERMGUARD reduce electricity consumption in my house?

    THERMGUARD will drastically reduce your electricity bills for heating and cooling your home. Depending on the design of your home, it is estimated that the insulation will pay for itself within 2-3 years.

  • How long will it take to install?

    An average home takes approximately 3 hours to complete.

  • How does THERMGUARD compare with insulation rolls?

    When fitted above the ceiling THERMGUARD fills every nook and cranny creating a totally seamless blanket, giving 100% cover. Tests undertaken in the U.S.A. proved that cellulose creates “air tightness” of a building and that when installed, performed on average up to 26% more efficiently, and up to 38% in extreme climates rather than rolls of insulation.

  • Will THERMGUARD make our home noticeably cooler?

    Depending on the method of construction used, e.g. large or smaller windows, concrete roof tiles or metal roofing sheets, the average temperature difference between inside and outside the home is usually in the region of ± 6°C.

  • What will happen if the insulation gets wet?

    THERMGUARD is manufactured from recycled newsprint which is fairly absorbent. However small drip leaks will not harm the insulation or the ceiling as they will be absorbed by the insulation. The next day when the roof space heats up, the moisture will evaporate out of the product, thus THERMGUARD is known as the “breathing insulation”. Obviously roof leaks should be repaired. In the event of a major infusion of water, such as a burst geyser, the insulation will be damaged. This occurrence would be covered under normal household insurance and can be repaired by a THERMGUARD contractor whilst the geyser is being attended too.

  • Is THERMGUARD insect and rodent resistant?

    The harmless household additives ensure that THERMGUARD is insect and rodent free. We have had reports from farmers where THERMGUARD has alleviated rat infestations.

  • Will THERMGUARD aggravate my family’s allergies?

    No, THERMGUARD is non-allergenic and non-toxic.

  • Can THERMGUARD insulate flat roofs?

    Flat roofs are THERMGUARDs specialty. In fact many installers of insulation rolls pass enquiries onto us. The reason for this is that THERMGUARD can be installed in the majority of flat roofs without removing the roof sheets completely. The roof sheets can merely be partly lifted, the insulation blown in underneath and then the sheets refitted.

  • Is the insulation process dusty?

    While THERMGUARD is being blown into the roof space a small amount of dust may come down through the trapdoor and from other sources, such as ill-fitting cornices. However, after installation the team on site will vacuum up this dust and the dust created in the roof space settles very quickly.

  • Downlighters – Are these a problem?

    No – THERMGUARD contractors fit protective sleeves above downlighters isolating them from the insulation. The correct treatment of downlighters is an important part of our professional installation service.

  • What about exposed wiring in the roof space?

    No damage will be done to any wires found in the roof as THERMGUARD is non corrosive. Because THERMGUARD is a loose-fill insulation, the wiring can easily be traced should maintenance be required.

  • How does THERMGUARD control sound?

    THERMGUARD is 4 times as dense as fiberglass and thus deadens sound significantly. If you live near a highway or airport the noise level in your home will be greatly reduced.

  • Does THERMGUARD settle over a long time period?

    Cellulose Fibre will settle slightly over time. However, thickness and R Values are calculated at settled densities and thus this is not a concern.
