• Acoustic Glass: Laminated glass (generally 6.4 mm or thicker) designed particularly to dampen acoustic waves.
• Low-E Glass: Coated to show heat back into the space, enhancing thermal performance.
• Obscured Glass: For personal privacy in bathrooms or ground-floor units.

2. Frame Type and Material

Can secondary glazing avoid condensation?

Yes. Condensation happens when warm, damp air hits a cold surface area. By creating a thermal barrier, the inner pane remains closer to space temperature level, which considerably reduces the possibility of condensation forming on the glass.
