- Toughened Glass: Required for safety in large systems or low-level windows.
- Low-E Glass (Thermal): Coated to reflect heat back into the room.
3. Frame Material and Finish
A lot of contemporary secondary glazing frames are made from slimline aluminum due to its strength and toughness. While standard white is the most inexpensive, going with customized RAL colors or wood-grain finishes to match existing interior décor will add to the cost.
