What makes ThermaProof™ different to other roofing insulation?

The superior water resistance of ThermaProof™ is achieved through a unique technology developed by BASF. Installation is simplified by the overlapping joints.

ThermaProof™ is identified by its orange colour. It is comparable in performance to extruded polystyrene (XPS) roofing systems. With the ease of installation and the need for high water resistance, ThermaProof™ has it covered.

How effective is ThermaProof™ as a thermal insulation material?

Extremely effective ...essentially because stabilized air is such a good insulator.

The thermal performance of a material is measured in terms of its resistance to the flow of heat. This thermal resistance is expressed in R values, the higher the number, the better the insulation. With the increased water resistance of ThermaProof™ the long term thermal performance is even better than standard EPS.

50mm thick Neopor® at 30 kg/m3 can give an R value of 1.39 m2K/W (BASF testing).

Does ThermaProof™ absorb water?

ThermaProof™ is an enhanced insulation product with improved water resistance properties. These enhanced properties are the result of the use of a unique raw material developed and commercialised by BASF.

Even under such an adverse and rare condition of prolonged saturation, ThermaProof™ suffers little adverse effects. It maintains its shape, size, structure, cohesion and physical appearance. The ability of ThermaProof™ to resist the adverse effects of moisture is exemplified by its widespread use in floats, marinas and other applications, which involve full or partial submergence in water for prolonged periods of time.

Does ThermaProof™ have a capillary action?

No. ThermaProof™ does not have a capillary action.

Does age affect the thermal performance of ThermaProof™?

No. ThermaProof™ consists of 96%-99% air and 4%-1% polystyrene, and nothing else. Because of its cellular structure ThermaProof™ is dimensionally stable, and will not settle over time. ThermaProof™ used and installed correctly does not deteriorate with age and as such is able to deliver constant R values for the life of the building.

Is ThermaProof™ strong?

Yes. ThermaProof™ exhibits excellent compressive and flexural strength and dimensional stability characteristics, at a very high strength to weight ratio.

Is ThermaProof™ resistant to chemicals?

It depends. It is resistant to virtually all aqueous media including dilute acids and alkalis and to methanol, ethanol and silicone oils.

It has limited resistance to paraffin oil, vegetable oils, diesel fuel and Vaseline, which may attack the surface of EPS after long-term contact.

It is not resistant to hydrocarbons, ketones, esters, paints containing thinners, and solutions of synthetic adhesives.

In roof construction requiring hot asphalt, care should be taken to follow recommended installation instructions for hot bituminous asphalt to prevent melting or collapse of ThermaProof™ insulation boards.

Is ThermaProof™ degraded by ultraviolet light?

Prolonged exposure to sunlight will cause a slight discolouration (yellowing) of ThermaProof™ insulation and cause some surface embrittlement.

Even so, the thermal insulation properties will not be affected unless exposure results in loss of thickness of the ThermaProof™ boards, although the friable surface can make bonding difficult. For this reason, ThermaProof™ insulation should be covered to protect it from UV light if it is to be stored in the open for extended periods.

Is ThermaProof™ durable?

Yes. Because ThermaProof™ is an inert, organic material, it will not rot and is highly resistant to mildew. It also provides no nutritional value to ants, termites, or rodents.

To prevent damage to ThermaProof™ by pests and insects seeking to gain access to the other materials in buildings which provide a food source, ThermaProof™ may be coated with a thin cement slurry.

Provided ThermaProof™ does not suffer mechanical damage or failure of any fittings that may be used, it should have a life equal to that of the building in which it is installed.

Is ThermaProof™ cost effective compared to alternative insulation?

Because of the high level of versatility of ThermaProof™ and the wide range of applications for which it is suitable, its cost effectiveness compared to alternative materials can generally be accurately assessed only on a case by case basis.

In many applications however, particularly where an element of structural strength is required, ThermaProof™ is the most cost effective insulation material available.
