principle of building RIKO houses is based on the use of natural materials and
therefore priority is given to heat insulation from wood fibres. Such insulation has
a large mass and stability, and therefore it does not shrink or sag. Its most
important quality is a favourable thermal lag because it protects the building
against overheating in the warm months. Other solutions of
thermal insulation are also possible, e.g. cellulose flakes, Rockwool,
polystyrene, sheep’s wool, etc. Apart from providing heat insulation, all materials
used also provide good acoustic insulation, water repellence, temporal and
dimensional stability, etc.
In places with potential wetness, insulation from expanded polystyrene
foam – Styrofoam – is used.
the RIKO Lesena construction system with solid glued wood walls, we use
exclusively stiff insulation boards because they are stable in size and do not
sag, which prevents the formation of thermal bridges. Soft insulation is used to insulate the
ceiling and roof elements or in places where the insulation is laid
horizontally and there is no danger that it could sag. Soft insulation is also used for
sealing small openings.
