Acoustic Glass: Laminated glass (generally 6.4 mm or thicker) designed particularly to moisten acoustic waves.Low-E Glass: Coated to show heat back into the space, improving thermal efficiency.Obscured Glass: For personal privacy in restrooms or ground-floor units.2. Frame Type and Material
While aluminum is the industry standard for Secondary Glazing Maintenance glazing due to its strength and slim profile, the intricacy of the frame impacts the rate. A set panel is considerably more affordable than a vertical sliding unit that must imitate the motion of an original sash window.

Fixed Units: These stay completely in place.
