Expanded polystyrene

Probably the best performing material on the market

Easy to use and very economical, the EUROMAC2 formwork block is without a doubt the most efficient on the market! It is composed of two expanded polystyrene panels with a patented metal frame molded into the walls. These spacers ensure the solidity of the walls and prevent any disassociation of the insulating panels over time.

The EUROMAC2 insulating formwork block is a high-performance material that eliminates thermal bridges, guarantees the best possible air tightness and effectively prevents any risk of condensation. It offers excellent thermal inertia to guarantee a constant temperature throughout the day, whatever the season.

Finally, the EUROMAC2 formwork block has excellent acoustic insulation against external noise. The insulating concrete block facilitates the construction of the walls of your passive house by allowing the realization of 4 complex operations in only one intervention: assembly of the walls, installation of the external insulation, sealing and acoustic insulation.

The EUROMAC2 insulating formwork block is at ease with all types of architecture, construction and finishing, in compliance with the RE 2020!

What is expanded polystyrene?

Expanded polystyrene (EPS) is a material obtained from the products of petroleum refining. At first glance, this is a far cry from ecological values!

However, EPS makes it possible to use styrene molecules, which are not used by the petroleum industry. The styrene is then expanded and heated with steam to obtain small polystyrene balls that can reach up to 50 times their initial volume. These beads are finally compressed to obtain sheets composed of only 2% of material and 98% of air! The production waste, less than 1%, is recycled and reused in the next cycle. This industrial process requires only steam and heat.

The advantages of expanded polystyrene

Each insulating form block is composed of two polystyrene walls joined by thin metal spacers inside which the concrete will be poured at floor level.

This installation technique is so simple that it is unanimously accepted by all builders!

It is a light material, easy to handle and quick to assemble since the formwork blocks fit together like bricks in a building set and do not require any fixing system (neither glue nor mortar).

EPS, a healthy material with no health risks

Composed of 98% air, expanded polystyrene (EPS) is inert, biologically neutral and stable over time, it is rot-proof. It contains no fibers and generates no particles. It does not support the development of bacteria and does not trigger any allergy. It is a non-irritating and non-toxic material used in many fields such as microbiology, food packaging and of course construction. Expanded polystyrene (EPS) guarantees excellent indoor air quality in your home.

Insulate well to save natural resources

Expanded polystyrene (EPS) guarantees perfect insulation and excellent thermal performance! In the field of building, its use allows to realize important energy savings by reducing up to 90% the heating consumption compared to a non-insulated house. Less heating means less raw materials lost in combustion.

Expanded polystyrene (EPS), a material ready for the RE2020

The Thermal Regulation RT2012 required that the consumption of new houses respect the limit of 50 kWh/m²/year. This standard is a first step towards the construction of passive or positive energy houses, labelled BEPOS. The Environmental Regulation RE2020 sets the maximum limit of primary energy consumption at 15 kWh/m²/year. Expanded polystyrene (EPS) already meets this limit. It goes even further by allowing the realization of passive houses which do not use any main heating system! Some insulations made with expanded polystyrene (EPS) reach the objectives of passive houses and do not require any external energy contribution, they are self-sufficient and do not pollute!

About Grey Energy

Grey energy defines the energy expenditure necessary for the production of a material and over its entire life cycle. This unit takes into account the extraction of raw materials, the transformation phase, transportation and the energy cost of recycling. Grey energy is evaluated in kWh/m3. Expanded polystyrene (EPS) represents a grey energy of 0.3 to 0.85 MWh/m3. In addition, EPS brings a perfect exterior insulation to the house and that changes everything!

A passive house built with EUROMAC2 insulating materials can do without gas and fuel oil! Expanded polystyrene (EPS) is the ideal material to build a passive or positive house! Much further down the list, solid brick, still widely used for traditional construction, has an estimated grey energy of 1.2 MWh/m3!
