The insulation owes
its unique qualities
to the in-built binder system. At the time of spraying, the
binder - waterborne polyvinyl alcohol polymer and the hardener
(disodium tetraborate) are being mixed together. On reaching the
surface, the resultant mixture is hardened into a gel engaging
the mineral wool in the process. The hardened binder is not
soluble in water, which means that the insulation coating,
composed of binding agents and sealants that expand in water,
will dry out faster than the insulation material. In addition,
the hardened polyvinyl alcohol will shrink at drying, as a
result of which a porous insulation coat is formed, exhibiting
ideal
adhesion properties while still preserving its shape. |

Heat conductance
of
is tested, being equal toe
l=0.033 W/mK. Heat conductance ratio reaches up to U=0.33 W/m2K
depending on the thickness and density. This is a very good
value, having in mind that after spray-on application, no
thermal bridge
forms due to the fine adhesion with the surface.
It is considered ideal for insulating ceilings and terraces but
can also find application in ventilated structural glazing
facades. The binder finds no parallel in road heat insulations
and can be used in difficult to reach narrow spaces, building
foundations, tunnels, subways, winter
garden structures and green-houses. |
