Bridges heat
With the constructive (monolithic) eps smartblock and smartblockplus
you totally eliminate thermal bridges, heat loss from inside the shell, or entry
of hot or cold from the outside. Due to fluctuation in the heat of the masonry building
avoiding losses of energy and condensation phenomena (of molds harmful to the
health women).
The block formwork eps smartbloc and smartblockplus avoids the above
issues through multiple teeth (patented internationally) (lower and upper block
to formwork) avoiding any possibility of error in the assembly and sealing of the
masonry completely every part in vertical and horizontal.
Instead of the traditional walls or frame structures with kerbs, beams and concrete
pillars unprotected or isolated internally and externally you create multiple thermal
bridges, where the thermal behaviour of a part of the building is completely different
than the masonry shell.
As a result of a poor performance thermal insulation of any kind it is (eps cork
glass wool etc.) leads to an increase in heat loss and causing the decrease in temperature
of the inner surface of causing condensation surface and saturation of masonry.
The photographic technique to infrared (Figure 02) allows to detect the presence
of thermal bridges. These can represent up to 30% 40% of total heat dispersed. The
thermal bridges are present at the beams, pillars, sills, balconies and even in
the presence of heterogeneity spread in the structure such as joints cement(horizontal
and vertical) between the concrete blocks of the so-called thermal bricks, cement
blocks that make up cell etc. the wall (Figure 03). To sum up the main causes of
a thermal bridge are:
- presence of different materials in the section of the building (eg masonry brick
shell thermal cement blocks, cement blocks cellular structure with reinforced concrete).
- discontinuity in the form of geometric structure (eg corners).
- breaks the layer of thermal insulation (eg columns, beams, window frames, etc..).
Effects of thermal bridges
The main adverse effects of thermal bridges are:
- Losses heat
The heat loss (Figure 03) arising from thermal bridges account for a substantial
heat loss on the building. The thermal bridges may also triple the transmission
of heat or cold in a section of the building, while representing only a small part
of the area.
- Condensation
The surface is a condensation of the most classic in thermal bridges (Figure 04
and 05).
It occurs when normal levels of relative humidity indoors in a thermal comfort are
combined with a surface temperature of the case that has lowest dewpoint.
- Formation of molds
The formation of mold happens when a particular combination of temperature, steam
and substrate favourable. The most common types of fungi (mold) (harmful to the
health of women) ripen inside the wall in the presence of high humidity and low
temperatures (0 - 15 ° C).
A thermal bridge, due to presence of high relative humidity and low temperature,
create favourable conditions and suitable for the formation of mold and odors unpleasant
no longer stop because of the internal wall.
- Damage to the surface structure and masonry
The cyclical variations of the surface temperature cause a pulverization of materials
that make up the structure (internal and external plaster pillars masonry kerbs
etc) 'status as noted in 50% of these cases are superficial damage due to the presence
of thermal bridges (Source: Fraunhofer Institut für Bauphysik) (Figure 04).
- Reduce heat comfort
When the inner surface temperature of a part of the structure (wall, floor, etc..)
Is at least two or three degrees of the temperature there is a feeling of discomfort
near the surface. This effect is particularly evident when large areas are involved.
A typical example is the area between a floor and not isolated outer wall. To limit
this inconvenience usually raises the temperature thus causing further loss of power
leading to high operating costs without obtaining a residential comfort.
To sum up all these issues are resolved in advance (under simplifying design life
you designers), and finally realized if the structure or envelope with the housing
system and constructive eps smartblock eps smartblockplus.
