Please pay proper attention to the protect
cap
and give certain explanation as you turn
it to the house owner.
Especially, an ample explanation is necessary
for not having
a child remove it or mistakenly comes off
during window cleaning.
Irregular allocation of the micro-spacers can be seen under most
circumstances.
Micro-spares are not used for the pattern
of the glass but are used for maintaining
the vacuumed layer.
It does not affect to the function of the
glass and such disorder of allocation has
no
problem with the function.
We, of course, ship you qualified vacuum
tested products.
Please be aware that dew condensation of
the sash cannot be reduced if you changed
the conventional glass with Spacia.
We cannot assure you 100% that dew condensation
of the surface of glass can be
eliminated, but majority of our customers
satisfy with it.
(Up to this point in time, we have received
no complaints from those premises
constructed under the Standard Type.)
We like you to give ample explanation to
your customer about soundproofing
(sound insulation) effect of Spacia.
You can feel the effect if you change conventional
glass with Spacia,
However, noises come not only through the
glasses but pass sashes as well as openings
of house. In some cases, noise level cannot be improved,
as sound cannot be seen,
so it is felt different depending on a person
who listens to the noise.
It is important for you to measure the noise
levels prior to the construction
and after the construction with a noise meter
(available at OSG) in order to clarify
and demonstrate the noise level reduction.
