Hi,
Thanks Harold.
Yes this material is mutch lighter then glass. Its only about 0.6 kg/dm3. The normal floatglass is 2,5 kg/dm3.
I use the 12 / 13mm thick material.
On the top i have only two small stripes of glass (100mm each). On the front- and backside. the rest is (how do you say them?) mull / gaze.
I hope you understand what i'm writing
Regards,
Markus
