In the 21st century,
only solutions that guarantee the right quality and measurable economic
benefits will deserve attention in every field of technology. This trend also applies to the
building materials industry, in particular to wall materials.

Cellular concrete is a
material commonly known and used in the construction of single- and
multi-family houses, industrial and service construction. It has a number of excellent
properties, thanks to which it is the best material for building walls. It combines the features of
construction and insulation material. In
order to reconcile these two features, cellular concrete must be distinguished
by adequate strength with a very favorable thermal conductivity coefficient. The 70-year period of using cellular
concrete in the world and the 50-year-old in Poland testifies to its good
durability. Cellular concrete
does not age, it is resistant to chemical and biological corrosion.
H + H Polska as a leader
in the market of cellular concrete in Poland began its activity on the Polish
market a few years ago by buying factories in Warsaw, Puławy, Gorzkowice,
Lidzbark and Skawina. And with
this strong accent he marked his presence on the Polish market and gained the
reputation of a reliable and reliable business partner. From the very beginning, the company
focused on the production and sale of high-quality cellular concrete blocks,
which resulted in the modernization of plants and adaptation of the material to
European standards. H + H Polska
has been a producer of cellular concrete in the following densities: 400, 500,
550 and 600.
From July 2009 at the
Gorzkowice plant, blocks in densities of 350 and 700 are available. In 2009,
the production of Termorex gray blocks in TLMB accuracy, ie blocks with the
highest dimensional accuracy, was started and currently Termorex blocks 400,
which are the nearest time will be available for sale. H + H Polska Sp. z o. o. as the only producer in Europe will produce gray blocks with a density of 400.
Blocks in light
densities, in turn, make single-layer walls, and all this is possible due to a
reasonable compromise between strength and thermal insulation, which is why
cellular concrete is one of the few building materials that allows homogeneous
walls to be erected without the need for additional insulation.
Table 1. U heat transfer
coefficient values for single-layer walls
made of H + H cellular concrete.
As can be seen from the
table of cellular concrete walls presented above, H + H meets the requirements
for U≤0.3 [W / m2K] for 350, 400, 500 blocks, thanks to which the investor can
choose and apply the material he needs without having to perform additional
building insulation.
This solution deserves
special attention due to:
• A favorable
microclimate in the room associated with the migration of moisture,
• The ability to
accumulate thermal energy regardless of the season and conditions outside,
• Easiness and speed of
erecting walls, eliminating the possibility of assembly errors, which often
happens in the case of sandwich walls.
• Lower wall
construction costs.
From the point of view
of ergonomics and labor consumption, elements of aerated concrete TLMB
varieties 350 and 400 are characterized by large dimensions of blocks with a
relatively small weight, which increases the progress of masonry work. Not without significance is the fact
that most of the masonry work is done by hand and the weight of the parts being
moved plays a significant role. Thanks
to the larger dimensions with a correspondingly low weight, we save time and
money when building a building. Dimensions
of TLMB cores are given in Table 2.

blocks and tiles produced in H + H plants
Thanks to the use of state-of-the-art technologies and the
continuous development of its products, H + H Polska Sp. z o. o. has the option of offering
products of the highest quality. Blocks
700 varieties produced at the plant in Gorzkowice designated PP6-0.70 are
characterized by the highest compressive strength of all offered H + H
products. As a result, the walls
are made with a higher load capacity, which allows the construction of higher
buildings (Table 3).
Table 3. Compressive
strength of H + H cellular concrete blocks
These blocks, however,
have worse thermal properties, therefore it is necessary in this case to
insulate the building.
To make single-layer
walls H + H offers blocks in densities 350 produced in the plant in Gorzkowice,
and blocks in density 400 produced in the plant in Skawina. These blocks do not have such a high
compressive strength, but they have the lowest heat conductivity coefficient λ from all masonry materials available on our market (table 4).
