The λ coefficient is specified by the manufacturer of the insulation, e.g. for mineral wool it is 0.035-0.045.
The lower the λ coefficient, the better the insulation (“thermal insulation in the room”).
The thickness of the insulation is calculated in accordance with the formula:
𝑔 = 𝑅 · 𝜆
where:
g – thickness of the insulation (partition) [m];
λ – thermal conductivity coefficient [W/m·K];
R – coefficient of thermal resistance of a layer of material [m²·K/W].
For materials with thermal resistance of , with λ=0,035 and R=2, the thickness of the insulation layer is 0.07m i.e.
7cm

Connecting the hot air distribution system.
The hot air distribution system allows the convective heat generated by the furnace to be used to heat other
rooms. Depending on the power of the device and building conditions, different solutions are used. Choosing the
right one should be entrusted to a person or company with experience in this field. A simple gravity system is
perfect for small single-story houses. On larger surfaces, sometimes it is necessary to use blowers forcing air
circulation.
CUBO cassettes allow a hot air distribution system connection from above. During assembly it is necessary to cut
out fragments of casing connections in places marked on the drawing. We gain uninterrupted airflow. Montage of
the tubes is takes place by to a special set of fittings with a diameter of 100mm. Cutouts allow with assembly to
thin or thick sheet metal.
