Single-layer walls are
the optimal solution for investors who value the speed of brickwork and
accuracy. The lack of additional
insulation layers significantly reduces the duration of construction and
protects the investor against manufacturing errors, also in the load-bearing
structure. Often, a wall that is
supposed to be insulated is made with less accuracy and worse materials. The time of making single-wall walls
is often 2-3 times shorter than the rise time of laminar walls.

It is worth noting that
laying an additional layer of insulation from materials such as polystyrene or
rockwool may worsen the acoustic insulation by up to 3-5 dB. In the case of homogeneous materials
and walls, this phenomenon does not occur.
Specially dedicated
material for single-layer walls are YTONG ENERGO blocks, which are available in
two thicknesses: 36.5 and 48 cm . 36.5
cm thick blocks allow you to build walls, which,
without additional insulation, meet the stricter thermal standards for
residential buildings. However,
YTONG ENERGO with a thickness of 48
cm does not require insulation,
even in the construction of energy-efficient houses, where the heat transfer
coefficient U must be less than or equal to 0.20 [W / (m2▪ K)].
YTONG ENERGO blocks are
masonified with a thin SILKA-YTONG adhesive mortar, 1- 3 mm thick . There
are also no vertical joints - they are replaced by a tongue and groove system. Such masonry is possible due to the
very high dimensional accuracy of the blocks (± 1.5 cm ). The
blocks adhere closely to each other and the heat remains at home.
Choosing YTONG ENERGO
blocks, you can opt out of additional thermal insulation, and thus, generate
savings already at the stage of building a house. In the future - significantly reduce
the heating costs of the building.
Bricklaying instructions
Bricklaying of walls
made of YTONG ENERGO blocks is carried out on the same principles as
bricklaying of walls made of other materials.
Masonry of each wall
should be started by laying a damp proofing on a board or foundations. For walls made of 48 mm wide YTONG ENERGO blocks , the recommended foundation width is
at least 32 cm .
Precise leveling of the
first layer is extremely important, because any errors and deviations will
affect the entire structure. For
this reason, the first layer of blocks is laid on a cement mortar with a ratio
of cement to sand 1: 3, starting from the corners. As a result, the first layer blocks
can easily be leveled using a leveler and a rubber mallet.
Subsequent layers of
blocks are laid on the mortar for thin joints with a thickness of 1-3 mm . Before applying the mortar to the
surface of the blocks, they should be slightly undone and cleaned of dust.
YTONG blocks have a
tongue and groove connection, thanks to which the mortar should only be filled
with horizontal joints.Vertical joints are filled only in places where there is
no connection to the tongue and groove, eg in corners or cut blocks.
The mortar is applied
with a trowel. In the case of
YTONG ENERGO blocks, gr. 48 cm is best used with a 24 cm wide trowel.
lintel
Lintels in walls made of
YTONG ENERGO 48 cm wide can be made as reinforced concrete
beams or finished YTONG YN and YF elements. The
simplest solution is to use two YTONG YN beams with a width of 24 cm arranged in parallel, or a lintel
combined with two YTONG YF beams. 17.5
cm and one YF 11.5 cm . More
demanding investors can make a lintel with two20 cm thick YTONG YN beams and fill the resulting gap with
insulation to improve the thermal parameters of the wall.
The advantages of YTONG
ENERGO blocks
• The hottest structural
material thanks to the λ = 0.095 W / mK coefficient
• Single-layer wall with
a coefficient of U = 0.19 W / m2K (width 48
cm )
• Available in 36.5 and 48 cm thicknesses
• No thermal bridges
thanks to thin joint mortar and tongue and groove joints
• Ergonomics of erecting
walls thanks to mounting brackets
• Minimal consumption of
mortar (5-7 l
/ m2)
• Fire safety -
non-combustible material (A1) and fire-resistant (REI 240)
• Vapor permeable wall
• Produced from only
natural ingredients: lime, sand and water
