	Excellent Mechanical Features: A thermal insulator must have good resistance to impact specially when insulating floors and for the external thermal insulation composite systems. The Master Iso boards have an excellent response to compression but they still have the elasticity needed to do the adaptation to the structure without breaking.
	Excellent Dimensional Stability: One of the biggest advantages of the Master Iso boards is its good behaviour under severe temperature changes. Portugal is tipically a country where there are very significant temperature changes in a short period of time (extremely hot days, extremely cold nights), and some materials are not prepared to those climate differences. The Master Iso boards have an extraordinary dimensional stability.This is very important if we talk about external thermal insulation composite systems (ETICS).
	Durability: The Master Iso boards have a life time of more thar 50 years, always keeping the thermal characteristics thanks to its resistance to the external elements such as: humidity, water, wind.
	Water and Humidity Resistance: The Master Iso boards are made of 95% closed-cells and 5% open-cells.Because of this kind of compositiion the boards do not absorb or transport water.The 5% of open-cells is for the structure to breathe. The amount of water that can be absorbed in case of direct contact, must be eliminated without changing the characteristics of the product.
	Lightness: In fact 95% of the volume of the Master Iso boards is gas. This feature gives to the boards a great lightness, low density and a high resistance to compression.Its low level of thermal conductivity also means less thickness, if we compare it with other thermal insulators, in order to ensure the same thermal performance.All these characteristics make the Master Iso boards one of the lighter and less thick solutions.
	Chemical and Biological Resistance: The contact with chemical products may change the characteristics of some thermal insulators.The Master Iso boards are resistant to the majority of the chemical substances used in buildings construction: Solvents Bituminous materials Glue components Wood protectors

In addition, the Master Iso boards are resistant to the effects of the plastic materials used in film, fuel, mineral oil, acids and diluted alkaloides, exhaustion gas and agressive atmospheres.

Master Iso boards do not putrefy, they are highly resistant to deterioration and have a neutral odor.

	Excellent Fire Behavior: The Master Iso boards are resistant to direct flame.In contact with fire there is no particles or drops fall.
	The Master Iso boards are CFC e HCFC's free
