Acoustic Glass: Laminated glass (generally 6.4 mm or thicker) designed particularly to dampen sound waves.Low-E Glass: Coated to show heat back into the room, enhancing thermal effectiveness.Obscured Glass: For privacy in restrooms or ground-floor units.2. Frame Type and Material
While aluminum is the industry standard for secondary glazing due to its strength and slim profile, the complexity of the frame impacts the price. A fixed panel is substantially more affordable than a vertical moving system that should simulate the movement of an original sash window.

Fixed Units: These remain permanently in location.

They offer a balance in between the low expense of fixed systems and the requirement of occasional access to the primary window.Horizontal Sliders: Ideal for casement windows, these panels slide left or right on tracks.Vertical Sliders: Designed to match the conference rails of conventional sash windows. These are frequently the most expensive due to the spring-balance systems required to hold the glass at various heights.Hinged Units: These open like a standard door or window.
