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.

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.

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

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
