Masonry armed steel concrete with formwork polystyrene expanded high–density in blocks thermal acoustic “to lose” EPS Smartblockplus® or ICF
The need to increase the thermal insulation in buildings in contact with the closures
perimeter vertical often led to the deterioration of certain characteristics of
the masonry itself, increasing the risk of condensation and mould. It therefore
intends to enhance the capacity of thermal wall to keep eps smartblockplus,
its thermal inertia. It is the heat accumulation and thermal resistance of the wall:
it is linked to the ability to accumulate heat and the conductivity of materials.
A certain 'heaviness', or mass of the wall combined with a low thermal conductivity
are the best solution, so it is right to have a balance between the weight front
and conductivity. The thermal inertia acts both with a magnitude of the wave damping
with external thermal mismatch of the same, that is, with the time delay between
the impact of the heat wave on the outer surface of the wall and its look with intensity
reduced, on the face of the inner wall. The effect of damping to reduce the size
of thermal construction, while the delay indicates the thermal environmental conditions
in which appear inside the condition of the worst natural climate external (minimum
night temperature in winter; Maximum sunshine,
summer). Indeed, the wall serves as a reservoir of heat accumulation
and thermal shock. It is therefore essential to take account of inaction heat to
exploit properly the benefits that can bring in terms of well-being, comfort and
energy savings.
The coefficient of transmittance to the surfaces of the walls (U) W / mqK characterizes
the flow of heat through an area of 1 unit square meters of wall for a temperature
difference of 1 degree Kelvin. The unit is the watts per square metre and can kelvin.
More low coefficient is more modest are the dispersion of heat and more high temperature
of the surface of the wall, which increases the comforts housing.
The system constructive to keep eps smartblockplus creates a seismic
bearing masonry concrete is particularly suitable for complex structures in seismic
zones. The advantages of a concrete structure are due to the almost total reduction
of costs and thermal bridges, more sound insulation and durability, and no radioactivity
harmful elements and a greater internal regulation.
The masonry bearing block eps smartblockplus formwork can be provided
by:
- Many forms of different sections, depending on the needs of structural building
- They improve the thermal insulation and noise thanks to the internal and external
isolation of the two panels that form the eps smartblockplus formwork
and concrete core (part structural and accumulation Heat) by reducing energy consumption
and heating costs. The formwork system constructive eps smartblockplus
has high stability characteristics (R), held (E) and thermal insulation (I). The
structure built with blocks formwork eps smartblockplus, after
being filled with concrete has a considerable mass frontal allowing disrupt and
dissipate the transmission of noise;
- weighing between 250th 350kg/mq and thermal conductivity ranging from 0.04 -0.02
-0027 W / mK, a high thermal power, high permeability steam and high thermal inertia.
