Although each installation is unique, roughly speaking you can expect a cost of between R56 – R75 per square metre of ceiling area. The price is of course dependant on roof size and geographical location. For a FREE personalised ceiling insulation quote please “Contact Us”

How long does Ceiling Insulation take to Install?

Expect the ceiling insulation to take about 3-5 hours to install for an averaged sized roof depending on your homes configuration. When requesting your FREE quote the site technician will be able to advise you more accurately. Pease also make use of this opportunity to advise us when the installation would suit you best.

What Sort of Temperature Difference can I Expect from House Insulation?

Thermguard ceiling insulation does not physically heat or cool your home. It does however prevent the transfer of heat (or cold) from the outside by up to 92%. We expect the difference between an un-insulated living space and one insulated with Thermguard ceiling insulation, to be in the order of 4-6°C. Each house is unique so this should be used as a guideline.

Is Thermguard Roof Insulation Safe for Humans and Allergy Sufferers?

Yes, unlike other House insulation products available, there are no cases of any human reaction to Thermguard ceiling insulation. Harmless household additives ensure Thermguard is fire retardant as well as insect and rodent repellent. These additives are both non-toxic and non-allergenic. Thermguard ceiling insulation is not harmful to rodents, animals and insects; instead they find the product irritating and will not nest within the product or use it to build a nest.

If Thermguard Roof Insulation is Made from Recycled Newsprint, Surely it will Burn?

No, Thermguard roof insulation is SABS tested and approved. The material is treated with several fire-retardant additives and thus, it will not burn or emit noxious fumes. It is fire tested under SANS 428 and is classified B/B1/2. Thermguard roof insulation has been known to afford protection of life and property by slowing the spread of accidental fire.

SANS 10177—“Does not have a propensity to support flame spread. No ignition of the insulation material and any resultant fire propagation was observed at any time during the test period”

Will Thermguard Ceiling Insulations Fire Retardant Treatment Last the Lifetime of the Building?

Yes, accelerated aging tests have shown that there is no degradation of the additives over time. Thermguard ceiling insulation has a limited lifetime warranty covers the fire retardant treatment for the lifetime of the building.

Is Thermguard Ceiling Insulation Environmentally Friendly?

Yes, Thermguard ceiling insulation is the greenest of the green products. It is used in buildings to conserve energy. Ultimately slowing the burning of fossil fuels which create greenhouse gasses. Cellulose fibre insulation is the only house insulation which is fully organic, biodegradable and manufactured from 80% recycled newsprint. Furthermore, it uses 15 times less energy to manufacture than glass-fibre ceiling insulation and 33 times less than polyurethane (plastic) insulation materials.

How does Thermguard Ceiling Insulation Compare to Other Insulation Materials?

Thermguard ceiling insulation has the highest R-value when compared to ALL alternative residential bulk insulation materials on the market. Added to its ability to give 100% coverage makes it the most effective residential house insulation locally available.

All the hard to reach nooks and crannies are 100% covered as Thermguard ceiling insulation is machine-blown into your ceiling. Unlike roll or blanket manufactured house insulations, Thermguard acts as a fluid covering your ceilings structure completely. When pumped into your ceiling Thermguard creates a seamless “blanket” of fibres preventing any heat gains and losses from occurring through gaps, obstacles and hard to reach places.  These inefficiencies would no doubt drastically reduce the house insulations effectiveness. Under installed conditions within ceilings Thermguard ceiling insulation is over 20% more effective than roll type house insulation materials.

What Can I Expect to Save on my Utility Bill?

Thermguard ceiling insulation will drastically reduce your electrical utility bills for heating and cooling your home. An estimated saving of 20% to 50% can be achieved depending on your current usage of heating and cooling systems. This will result in the house insulation paying itself off within 2-3 years, with only savings to follow.

Is the Product Guaranteed?

Yes, Thermguard ceiling insulation has a lifetime guarantee and will last the lifetime of your roof. It should be noted that Thermguard in no way becomes hard, or solidifies over time.

Can I Install Thermguard Over my Existing Insulation?

We generally recommend removing old insulation material first to ensure the newly installed Thermguard achieves 100% cover of the ceiling. The old non-performing material can be removed from your ceiling and disposed of if requested.

What Happens if Thermguard Ceiling Insulation gets Wet?

Thermguard ceiling insulation is manufactured from recycled newsprint which is fairly absorbent. 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 from the product. To avoid any chance of ceiling damage, roof leaks should be repaired as soon as possible.

In the event of a major infusion of water such as a burst geyser, although the Thermguard ceiling insulation may help to contain the waters spread. The insulation will regrettably be damaged and the excess weight may cause mechanical failure of the ceiling itself. We can replace the damaged insulation after the geyser is repaired. The cost would be covered under your normal household insurance. Thermguard ceiling insulation will not develop mold, even if left wet/damp for long periods.

What is the Recommended Thickness for Ceiling Insulation?

Under SANS 10400-XA each area of the country has different recommended R-values depending on the climatic region it falls into. The material thickness required is therefore determined by its R-value. In most unprofessional installations the ceiling insulation material used are very thin or otherwise ineffective materials are used. Thus, the effectiveness is very low, leaving the homeowner unhappy with the resulting poor performance of the installation.

Typically, Eskom recommends a cellulose roof insulation thickness of 135mm for Johannesburg and 115mm for Pretoria.

Can Thermguard Ceiling Insulation be Installed in Flat Roofs?

Yes, this is one of the many advantages of cellulose fibre house insulation. Thermguard ceiling insulation can be installed in most flat roof houses with minimal roof sheets being disturbed. In some cases however the recommended insulation thickness may not be possible due to space constraints.

Does Thermguard Ceiling insulation “Settle” Over Time?

All cellulose fibre will “settle” slightly over time. However R-Values are calculated at settled densities. As a homeowner you would not need to “top-up” the roof insulation after a period of time. Furthermore, Thermguard ceiling insulation in no way becomes hard or solidifies over time.

How Does Thermguard Ceiling Insulation Control Sound?

Thermguard is 4 times the density of glass-fibre roof insulation and thus deadens sound significantly. When installed in the ceiling Thermguard drastically reduces unwanted noise between adjacent rooms as well as noise created by nearby busy roads, highways and airports. Additionally, Thermguard ceiling insulation can also be installed within partition walls to reduce noise and increase privacy in office spaces. Thermguard reduces the transmission of sound by up to 45 decibels.

What about Exposed Wires in the Ceiling?

Thermguard ceiling insulation will not cause any damage to wires or pipes found in the roof as it is non-corrosive. Should maintenance be required, Cellulose fibre, being a loose-fill house insulation means wiring can easily be traced and the material moved with bare hands for access. In addition, Thermguard ceiling insulation does in no way solidify over time.

Can Thermguard Ceiling Insulation be Installed Over the Downlighters in my Ceiling?

Yes, we install cones over each downlight to ensure the material never comes into contact with the light fitting. It is important that the material remain separated from the fitting as some downlighters, especially the 50w halogens, can reach temperatures of up to 300°C. The correct treatment of downlighters is very important. Most “less professional” installations may see the insulation material simply cut short or moved away from the downlighters creating an inefficiency of up to 30%. When installing Ceiling insulation always ask how the downlighters are treated. The incorrect treatment of downlights could pose a serious fire risk.
