Bringing walls in the H + H system
is building from a very good quality material, which is H + H cellular
concrete. The H + H system provides a full
range of products: blocks, tiles, lintels, fittings, ceilings and thin-layer
mortars. Deciding to build in the H + H system, we reduce the cost
of making the wall ready and shorten significantly the time of the investment
compared to other building materials. In summary, working with H + H
cellular concrete is pure pleasure. Cellular concrete is an
environmentally friendly material because it is made from raw materials that
occur in the natural environment. Its production consists mainly of:
quartz sand, lime, cement, water and the agent causing the fluffiness of the
prepared product. Here are 10 advantages of why it is
worth building H + H aerated concrete.

quartz sand, lime, cement, water and the agent causing the fluffiness of the
prepared product. Here are 10 advantages of why it is
worth building H + H aerated concrete.
1. The hottest building material
It has been known for a long time
that the best heat insulator is air. In the structure of aerated autoclaved
concrete, air occupies 60-85% of the total volume, which is why buildings made
of cellular concrete significantly reduce the need for heating or air
conditioning in comparison to other masonry materials. H + H cellular concrete is
characterized by extremely favorable thermal insulation; one of the best among construction
materials used for erecting external partitions. Thanks to this property, it is an
excellent material for building single-layer walls. The measure of thermal insulation
is the thermal conductivity coefficient, which is dependent on the volume
density, raw material composition and moisture of a given material. The exceptionally favorable (low)
value of the thermal conductivity coefficient λ (W / mK) of H + H cellular concrete blocks allows to obtain walls with a low
heat transfer coefficient U (W / m2K), enabling single-layer walls to be
erected without the need for thermal insulation.
2. Lightweight with high
compressive strength
One of the most valuable properties
of aerated concrete is its low volume weight. Thanks to its lightness, it enables
adaptation of existing places, eg attics and attics, in which excessive
construction of structures created many years ago is not allowed. 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. High compressive strength of
aerated concrete allows elevation of up to 5 storeys without reinforcing the
structure. The compression strength of 700 kg
/ m3 blocks is 7.5 MPa.
3. Non-flammable in the highest
fire resistance class
Due to its purely mineral
composition, cellular concrete is classified as a non-combustible building
material in the highest fire resistance class A1. This means that during a fire it
does not emit any harmful or poisonous substances for users. It is resistant to fire at
temperatures up to 1200 ° C and, unlike other building
materials, it is heat-resistant. Fire resistance of cellular
concrete walls reaches 4 hours, meeting the highest requirements of Polish
regulations in the field of fire protection. The walls of aerated concrete
prevent the spread of fire, and thus protect life and property, and provide a
peaceful evacuation of people in the event of fire hazards
4. Easy to process
Blocks and tiles made of aerated
concrete using the simplest tools can be freely processed: cut and make holes
of various size for electrical and plumbing installations. It is particularly easy to erect
walls from elements connected to a tongue and groove with a mounting bracket. Blocks can be cut manually using a
hand saw or band saw. It is easy to make installation
grooves in the already-walled walls, which allows for quick work progress. A well-made wall of cellular
concrete blocks is ready for plastering.
5. Good acoustic isolator
Walls made of aerated concrete have
a greater ability to dampen sounds compared to other building materials of the
same density. Thanks to this, the walls have good
acoustic insulation and provide a quiet, comfortable apartment and some
protection against intrusive sounds from both outside and inside the building
6. Durable and pleasant to use for
many generations
Cellular concrete does not age. It is resistant to chemical and
biological corrosion as well as to mold, bacteria and also acid rain in
industrial regions. The chemical composition of aerated
concrete blocks the formation of efflorescence and salivation, fungi and
harmful micro-organisms. Cellular concrete retains its
properties throughout the life of the building, and the walls made of it
provide a pleasant microclimate interior and have a positive effect on the
well-being of the household, creating the right conditions for both work and
rest. Pores in the cellular concrete favor the absorption of
excess moisture from the air inside the building and give it away when the air
is too dry. Thanks to the appropriate
thickness, single-layer walls accumulate and release heat depending on the
temperature inside and outside the building, keeping it at a constant level. This process takes place both in
the daily and annual cycle. In winter, it protects against a
sudden cooling down and in the summer its excessive overheating.
7. Large heat capacity
In cellular aerated concrete rooms
there are optimal thermal and humidity conditions, it is neither too dry nor
too humid. Such a microclimate is the result
of vapor permeability of cellular concrete. Cellular concrete absorbs the
excess of air in the room, and releases it when the room is dry. The walls of H + H aerated concrete
are characterized by high thermal inertia. The heat transfer process from one
side of the wall to the other is, therefore, very slow, four times longer than
in traditional insulation materials. This ensures high thermal comfort
of the rooms: in the winter it is warm and in the summer cool
8. Energy saving
In single-family houses, the
largest heat losses occur on external walls. In an extreme case, even 35% of
heat from the whole house "escapes" through external walls. Therefore, the correct selection of
elements for the construction of external walls is extremely important from the
point of view of future operating costs of the building. The concept of an energy-efficient
house is increasingly appealing to investors' awareness. Energy efficiency becomes a
desirable feature of the building and an important criterion for good design
and quality of workmanship. For a building user, this results
in measurable benefits in the form of low heating costs. You should start thinking about
energy saving your home already at the house design stage. The very shape of the building and
its orientation towards the world's sides is of great importance for future
energy efficiency. In order to heat buildings
efficiently and cheaply, it is first of all necessary to limit heat losses
through external barriers: roofs, walls and floors.Thanks to the use of H + H
cellular concrete, the savings associated with heating the building are higher
than with the use of other masonry materials.
9. Saving money
Why can we save money by choosing H
+ H cellular concrete? First of all, H + H cellular
concrete is the material from which we build a house, saving money on labor the
fastest. Secondly, by making one-layer varietal walls of 350 and 365 mm thick, we will save on the insulation of the
building, because the bricked wall has a coefficient of U = 0.25 W / m2K. Thirdly, the smooth surface and
minimal dimensional deviations ( 1.5 mm ) will allow the use of thinner
plasters, which is impossible when using other building materials. Fourthly, when masonry (gluing) for
thin-bed mortar, we will use less mortar, the consumption of which also affects
the unit cost of 1 m2 of the wall. Therefore, it is very important not
to be guided by the unit prices of materials, because they can be very
confusing. Calculate the cost of making the
wall ready
10. Time saving
When building a house, we want to
enter it as soon as possible. However, building a house requires
time. To limit the time of building a house, you need to use
reliable and proven solutions. Building in the H + H system allows
to minimize the time of bricking the house, because all elements are made of a
homogeneous material and easy to process. Bricklaying time is also shorter
because we use only 7 blocks per 1m2 of the wall, which is impossible in other
technologies. The use of finished lintel beams
results in shorter bricklaying time and the lack of technological breaks
related to binding and hardening of concrete in traditional lintels. In addition, the very high
dimensional accuracy of H + H blocks allows you to limit time during
installation and finishing works
