It is the best energy-saving insulator of all construction
insulators for having low heat conductivity.
Since it is made of PIR foam, even
small thickness can satisfy the energy-saving
design standard of buildings and it prevents
heat conduction perfectly and also
allows the maximum use of space.
PIR, the hard urethane foam insulator,
is a quasi-noncombustible, high-molecular
construction material with improved functions
and therefore carries the outstanding
flame-resistant property compared to
Hard urethane foam (PIR) carries the outstanding
noise-insulating property so as to block
noises coming from the outside the building and
it also makes the whole space quiet and
cozy by preventing the leakage of indoor
Even amongst the same 'A' class insulators,
a hard urethane insulator is the best and
ultimate solution, considering the excellent
energy efficiency and slimness.
This insulator adopts vapor barriers and PE coating papers
as surfacing materials so there is no need to form separate
dampproof layers and such advantage shortens
construction schedule and also saves construction costs.
This insulator prevents dew condensation on the internal surface
of walls and on the inside and also prevents the
performance of insulators from degrading.
