CHOOSING THICKNESS AND KIND OF THE WINDOW PANE
Thicker sheet will of course insulate better both for sound and temperature though the weight is a consideration here too.
CALCULATING WEIGHT
CALCULATING WEIGHT
You can calculate the weight by the following formula:
0.855m x 1.384m x 6 mm x 1.19 = 8.44 kg
The most common thickness manufacturers have is 3, 4.5 and 6 and more mm. I wouldn't recommend more than 6 mm.
As
for the kind of plastic, there is Acrylic and Polycarbonate. The former
is about 2x cheaper than the latter. They say polycarb will last longer
without going yellow but this is not such a worry since the internal
window is behind glass and glass has some UV qualities that will protect
the plastic against sun. If it was outside, that would be another
story.
Polycarb is said to be less fragile than Acrylic
and might have better anti-scratching properties but that differs by
manufacturers. There are different kinds of both depending on the
manufacturer.
For me Acrylic was
good enough. If you go to your supplier, ask for a sample. I was
surprised how clear it was. Indiscernible from glass. I chose 6 mm
thickness.
This
thickness is great for one particular trick. When you get 4.5mm plastic
cap profiles, sometimes called "U" channels (they are 4.5mm but they
are actually slightly larger), it will be a perfect fit and will serve
as the window plastic edge. More on that later.
Have a look at the picture and compare for yourself. It's up to your preference. Just make sure that you buy the same shade.
From a sample (that I am sure your supplier will give to you) you can make yourself a little model of your window to see how thick it will be. You will need that to mark it on the new wooden recess to mount steel profiles.
