Acoustic Glass: Laminated glass (typically 6.4 mm or thicker) created particularly to dampen sound waves.Low-E Glass: Coated to reflect heat back into the room, improving thermal performance.Obscured Glass: For personal privacy in restrooms or ground-floor units.2. Frame Type and Material
While aluminum is the industry requirement for secondary glazing due to its strength and slim profile, the complexity of the frame impacts the cost. A set panel is substantially cheaper than a vertical sliding system that needs to mimic the movement of an initial sash window.

Repaired Units: These stay completely in location.
