Hi,

I'm planing to build sunrom, wintergarden or etc...

I have plan to have some dark wals maded from glass outside ( ISO 4 mm sand
brushed float + 4 mm mirror ) and rigips / knauf and terwool inside.

Mirror will be pointed to outsided glass - 4 mm float brushed with sand and
I'm worry about thermal shock.
What will be happen when direct sunlight burn over sand brushed float,
behind is mirror pointed to the sun.

Overheated?!

Will it crack?!
Who is overheated mirror or sand brushed float, or both?

Final whish is to get opaque surface, when opalescent glass is anavailable
( Croatia )...


Please help me with some ideas, any ideas...

Thanks.
