I’m using Optima Windows
Laminate…7mm++ can’t remember the specs and price too long ago. But sound proofing and build quality is top notch.

It was expensive but boy, nothing to complain about for the product delivered.

Feedback on my glass configuration: 4mmTempered + 4 PVB + 4mm Tempered LowE + 12 Airgap + 4mm Tempered works very very well. Glass barely gets warmer than ambient. Direct sunlight around 38°C top temperature.

Installation and frame were soso. If you can tahan a standard installation then its fine. I would have expected more but well. I assumed this would be the case. Frame margin or error is sometimes visible, workmanship is OK but not great. If anyone wants I can share contractor. Cannot give an unreserved recommendation if you want to retrofit.
