GENERAL TERMS
The formwork polystyrene foam sintered –formwork of polystyrene expanded in blocks thermal acoustic “to stay” EPS SmartBlockPlus or ICF is an environmentally friendly material derived from oil.

Through an industrial process, we derive small pearls transparent to achieve the formwork of polystyrene expanded in blocks thermal acoustic “to stay” EPS SmartBlockPlus or ICF, plus pentane during processing, a hydrocarbon gas that acts as expanded that at the end of the expansion process evaporates. The polystyrene beads expand up to 20-50 times their original volume when in contact with water vapour temperature above 90 ° C.

The next step is to weld together the pearls expanded, and after sintering, you print the formwork of polystyrene expanded in blocks thermal acoustic “to stay” EPS SmartBlockPlus or ICF obtaining a form so rigid, flexible, high-density, light weight, with a molecular structure closed cell, which holds its own house in the air and then the exclusive property of thermal insulation. Yes get these exceptional thermal insulation characteristics to forms, but still with no air convective within expanded polystyrene beads.

Key points:
• For most industrialized countries have an obligation is to reduce emissions of greenhouse gases by at least 5% below their level in 1990, in the period ranging from 2008 to 2012.
• The countries themselves have to provide protection projects woods, forests, agricultural land, which absorb carbon dioxide, (so called ''Carbon Sinks', that stores CO2). They can also earn 'Carbon Credit' helping developing countries to avoid polluting emissions, exporting clean technologies. Each country will also implement a national system for the estimation of gas emissions. It will be created a global system to compensate.
• The signatory countries will meet if sanctions fail to achieve the objectives. Flexible more rules for developing countries. Why the Protocol becomes binding at the international level, must be ratified by at least fifty-five countries. This is happening now: the Russian parliament in November'04 has translated into law as decided (September 30'04) by the government of (Vladimir Putin). The protocol shall enter into force after 90 days in February 2005. In 2001 the United States withdrew from the table of the agreement, saying that it would damage the US economy and would unfairly favour the developing countries (the use discharged into the atmosphere 33% of the greenhouse gas emissions worldwide). The Australia is confirmed the refusal to join the China if they disinterest. Here's greenhouse gas emissions of which must be limited: Carbon dioxide (carbon dioxide =CO2) Methane (CH4) =Nitric oxide (N2O) =Hydro fluorocarbons (HFCs) = for fluorocarbons (PFC) =sulphur hexafluoride (SF6) Mos. The scientific world talking about all these gases in terms of "CO2 equivalent" with respect to their ability change climate, and this policy is adopted by the project impact of zero of CERAMICHE BERNINI S.r.L ITALY with system formwork blocks thermo acoustic “to stay” EPS SmartBlockPlus or ICF To achieve these targets, the Kyoto Protocol proposes a series of measures: Establish or strengthen national policies to reduce emissions (development of renewable energy sources, energy efficiency improvement, promotion and application of advanced building technologies for energy saving of eco sustainability forms of sustainable agriculture, etc.). Cooperate with other states acceding to the Protocol (exchange of information and experience, coordination of national policies for the purpose of efficiency through cooperation mechanisms such as emission rights, Joint Implementation and the Clean Development Mechanism).
FIRE BEHAVIOUR OF EPS (POLYSTYRENE OF HIGH DENSITY) REPORT NASA (USA)
The system constructive formwork of polystyrene expanded in blocks thermal acoustic “to stay” EPS SmartBlockPlus or ICF ignites only about 450 ° C. In building is used as thermal insulation and noise pollution for more than 50 years as a safe and self material for his composition and delayed the spread of flame created by the fire, characteristic obtained with appropriate additives not harmful, to cover the nature fuel This compound, in which the propagation ceases to be less of the cause of ignition. The EPS (expanded polystyrene of high density) to about 200 °C reaches the glass transition temperature in order to change their physical state to a solid seed fluid. Transforming the polystyrene panels in a sort of membrane that lies on the panel EPS which borders and protects the masonry concrete structural both internally and externally by making it completely impermeable to gas or fumes. The volume occupied panels by polystyrene (EPS) that give shape to formwork of polystyrene expanded in blocks thermal acoustic “to stay” EPS SmartBlockPlus or ICF are made up of 98% air simply because the EPS (expanded polystyrene of high density) under the action of the fire does not produce any Training gas as other elements building. The temperature developed during the fire only increases its pressure inside the watertight room occupied by the nucleus of concrete masonry where none and enough oxygen to fuel combustion, not coming to the state that experimentally is named as (outbreak). This is not entirely caused by the combustion of gases produced by EPS (expanded polystyrene of high density) that form the system constructive formwork of polystyrene expanded in blocks thermal acoustic “to stay” EPS SmartBlockPlus or ICF insulating part of the structural walls. Right under the action of a fire occurs only increase the air pressure inside the volume previously occupied by the panel EPS which gradually loses the permeability wall to gases emitted by concrete action under fire. The EPS polystyrene foam panels of high-density that shape the formwork in blocks thermal acoustic “to stay” EPS SmartBlockPlus or ICF is not designed to withstand an increase in pressure beneath the action of the fire is extinguished by the masonry but by no means out as other materials Insulating. The polystyrene, which consists of carbon and hydrogen, is by its nature a combustible material. It begins its decomposition at around 230-260 ° C, with release of flammable vapors, but only 450-500 ° C is an ignition. The subsequent spread of flame occurs spontaneously of EPS normal, if there is sufficient supply of oxygen, while of EPS to improved fire behavior (EPS / RF), obtained with appropriate additives, the spread ceases to be less the cause of ignition.
The regulations distinguish the behavior of combustible materials with an appropriate ranking.
The polystyrene is usually naked in classes D and E or higher if coated (according to EN 13501-1).
There are some general comments on the fire behavior of polystyrene expanded- polystyrene foam that can usefully serve for a risk assessment of use.
1) The EPS requires some energy for its ignition, a spark or a lit cigarette is not enough.
2) The contribution of polystyrene in terms of energy balance in a fire is modest in relation to its low density:
1 cubic dm EPS of 15 kg / cubic m has a calorific value of 590 j j 9200 against the same volume of spruce wood.
3) The EPS expanded polystyrene is generally protected from other materials and did not require immediate availability of its combustion (about 130 times its volume).
4) The burning may develop as toxic gases, mainly carbon monoxide, not unlike the wooden materials in the building or the furniture but in much smaller proportion.
The combustion produces no dioxin of EPS therefore not reflected in the flue gas produced during a fire. The substances emitted by burning of EPS (Polystyrene Foam sintered).
The EPS behaviour - polystyrene expanded- polystyrene foam:

Decomposition temperature 300-400 ° C first signs of failure.
Temperature of ignition of the flame 360-370 ° C (DIN 54836) 345-360 ° C (ASTM D1929)
Self- ignition of temperature 450-500 ° C 490 ° C (ASTM D1929)
Self-ignition of temperature of styrene 490 °C.
The polystyrene expanded - polystyrene foam is a hydrocarbon composed of hydrogen and carbon. The self contains an additive that allows the material to obtain a flame retardant spread...
With a flame temperature rising to the polystyrene begins to collapse and after melt, then burn.
In case of fire combustion products will depend, of course, since this level of temperature.
When the polystyrene flame burns with stable and good oxygen, the main products of combustion are carbon dioxide, carbon monoxide, water and particles.
During a fire are the presence of carbon monoxide and the depletion of oxygen that usually makes it more dangerous to the environment. If the flame is not well stabilized, there will be less burning generating the "white smoke". This is due to the formation of condensation droplets on the product not completely burned.
Of greater interest, rather than the exact composition of the products of combustion from EPS, the toxicity of gases produced. Studies carried out by Hilado et.al ( "Toxicity of pyrolysis gases from natural and synthetic materials", Fire Technology, May 1978, p.136) and Oettel and Hofmann ( "Experiments on toxic hazards with expanded polystyrene," Fire International, July 25 1969, p.20) and others (review Zorgman, TNO report B-79-504 1979 ... .. TNO) showed that, compared to the usual building materials (cork, cotton, wool, plywood, etc.), If the fire EPS presents the risk of toxicity minors (based on test animals) on a volume.
Toxicity little difference was found between the products of combustion materials in polystyrene and normal self.
In conclusion, and good clarify that the formwork in EPS (expanded polystyrene high density) ind formwork of polystyrene expanded in blocks thermal acoustic “to stay” EPS SmartBlockPlus or ICF not sublime created by the fire but only you self-extinguish gas without creating harmful to the health of humans as other insulation materials .
