STRUCTURAL THEORY

Milestone Ventures EPS-3D ICF Structural Panels far surpass the strength of conventionally framed structures. These panels are very strong when loaded axially (wall panel) because they perform as a composite column. The rigid foam steadies the relatively flexible skins over every square inch of their surface to prevent them from buckling. Figure 2A illustrates this effect.

Panels are also very strong in bending such as when a wall is under a wind load, or a roof panel is

loaded with a heavy layer of snow. In bending, a panel behaves like an I-beam with very wide

flanges and a web as thick as the panel is wide (Figure 2B). The skins act like the flanges by

carrying the resultant compressive and tensile stresses. The core acts like the web by resisting shear forces and providing continuous support to the skins to prevent them from buckling and wrinkling. In special applications, Interform’s injection process makes it possible to mold a variety of structural elements, such as laminated beams inside the panels for additional support.

COMFORT

The panel can be sized to achieve the welfare conditions of thermo- hygro and acoustic required by the different climatic conditions.

RESISTANCE

The wire mesh incorporated in the CLS and patented technologies for the implementation of the panels offer greater resistance to nodes in the event of structural static actions such as seismic.

STEEL

External meshes and connectors are made of drawn steel wire, hot galvanized, low carbon, welded for electro fusion, having a high threshold of breakage.

EXPANDED POLYSTYRENE SINTERED (EPS)

The raw material comes in glassy Granules, obtained by the polymerization of styrene, a liquid compound of carbon and hydrogen. The granules are expanded in two Phases to obtain blocks of density Between 15 and 25 kg/m³, composed of 2% of the beads and 98% air.

Storage time capacity insulation

No water absorption by capillarity
Imputrescibility

FEATURES EPS (2/3)

WATER RESISTANCE

The EPS is waterproof. The water does not dissolve the EPS and is only minimally absorbed in the interstices between the granules residues. Absorption by capillarity is zero, as well as the absorption of humid air.

DURATION AND ENVIRONMENTAL SAFETY

The EPS is stable chemically and biologically. Not support the growth of microorganisms, mold or fungi, therefore, does not rot Does not constitute danger of environmental pollution during production or application. Vouch for an unlimited period of performance required

FEATURES EPS (3/3)

FIRE RESISTANCE

EPS normal combustible; decomposition occurs at about 230 to 260 °C with release of flammable vapors, but only 450 500 °C we have the ignition. EPS suitably treated with additives, flame spread ceases to be less the case of initiation. The EPS burns only if exposed, in a fire generates only 8% of the heat emitted by an equal volume of wood in a fire and spread to a quantity of toxic gases (carbon monoxide) even less.

RESISTANCE TO WATER VAPOR

The EPS, impermeable to water, is permeable to water vapor and therefore breathable, this means that in isolated environments with EPS mold and mildew is not formed.

MECHANICAL STRENGTH

STATIC

The panels, with their weight ranging between 4 and 15 kg / m², remain light to the installation, after the assembly is applied the concrete that incorporates the complete meshes and the static function of the artifact, ensuring a high resistance operating

SEISMIC

The presence of wire mesh panels and structural nodes ensures high resistance to seismic actions.

THERMAL RESISTANCE

The EPS has high insulating properties. The low thermal conductivity is due to the structure of the material, consisting of 98% air trapped in cells of a size to prevent convective movements.

SOUND RESISTANCE

The presence of EPS offers a high degree of acoustic insulation

FIRE RESISTANCE

The EPS is poorly flammable; requires a volume of combustion air equal to 150 times its volume so the fire can destroy it completely. If protected by two layers of concrete, as the panel put in place, can not burn.

RESISTANCE TO LIGHTNING

Galvanized steel meshes on the façade panel EPS contribute to a metallic structure similar to a Faraday cage, which can provide protection
against lightning

Energy Efficient Low Cost Housing Schools & Hospitals

The 200 underprivileged regions are situated in 27 out of Indonesias 33 provinces, with East Nusa Tenggara to host the largest number of the houses 1,440 followed by Papua with 1,260 houses. Helmy said he expected even a larger number of low-cost houses to be built in underdeveloped regions next year, including in Indonesias outermost islands, estimated to be inhabited by 20,000 families.

By the end of 2013, we hope 100 percent of the outermost islands become free from shabby houses, he said upon signing the MoU.

Djan, meanwhile, said his ministry was developing a total of 60,000 houses this year, which fell short the 4.8 million needed.
