How effective is ThermaAdvantage® 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. The R value of the most commonly used Class (Class SL) is 1.13 for every 50mm thickness. Thus, 44mm of this Class of EPS delivers an R value of 1.0. With foil faces, the R value of ThermaAvantage® is even higher.
Does ThermaAdvantage® absorb water?
ThermaAdvantage® is a closed cell and cannot absorb water. During the process of moulding a block, tiny channels are formed between the EPS particles. If the material is immersed in water these tiny channels can be filled with water. After immersion for more than 360 days, there may be up to 6% water content by volume, which has entered the channels.
Even under such an adverse and rare condition of prolonged saturation, EPS suffers little adverse effect. It maintains its shape, size, structure, cohesion and physical appearance. The ability of EPS 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 ThermaAdvantage® have a capillary action?
No. ThermaAdvantage® does not have a capillary action. ThermaAdvantage™ is ideally suited when the insulation material is in contact with the ground.
Does age affect the thermal performance of ThermaAdvantage®?
No. ThermaAdvantage® consists of 94% - 98% air, 2% - 4% polystyrene and nothing else. Because of its cellular structure ThermaAdvantage® is dimensionally stable, and will not settle over time. ThermaAdvantage® 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 ThermaAdvantage® durable?
Yes. Because EPS 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.
Provided ThermaAdvantage™ 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.
Does ThermaAdvantage® burn?
Because ThermaAdvantage® insulation boards contain a fire retardant additive, they do not present an undue fire hazard when correctly installed. Like many construction materials, ThermaAdvantage® must be considered combustible and constitutes a fire hazard if improperly used or installed. The material contains a flame retardant additive to inhibit accidental ignition from small fire sources.
Does ThermaAdvantage® give off toxic fumes?
The level of toxicity of ThermaAdvantage® in a fire situation is no greater than that of timber and other commonly used building materials; the same toxic gas, carbon monoxide is produced. Also produced are carbon dioxide and soot (carbon). There is no emission of such gases as hydrogen cyanide or hydrogen chloride.
Is ThermaAdvantage® cost effective compared to alternative insulation?
Because of the high level of versatility of ThermaAdvantage® 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, ThermaAdvantage® is the most cost effective insulation material available.
EPS is the only insulation material that in practical, economic and efficiency terms can be applied to all areas of building constructions – ceilings, roofs, walls, floors and under slab – to provide superior standards of thermal insulation. That’s why EPS is the ultimate insulation.
