- Acoustic Glass: Specially laminated to disrupt acoustic waves for optimum sound reduction.
- Toughened Glass: Required for security in big systems or low-level windows.
- Low-E Glass (Thermal): Coated to reflect heat back into the space.
3. Frame Material and Finish
The majority of modern secondary glazing frames are made from slimline aluminum due to its strength and sturdiness. While basic white is the most cost effective, going with customized RAL colors or wood-grain surfaces to match existing interior decoration will contribute to the rate.
4. Installation Complexity

The Benefits of Investing in Secondary Glazing
While the in advance cost can be substantial, the return on financial investment (ROI) is realized through improved comfort and lower utility bills.
Considerable Heat Retention
Secondary glazing can minimize heat loss through windows by as much as 60%. By creating an extra barrier, it eliminates drafts and keeps the internal surface area of the window warmer, which considerably minimizes the need on central heater.
Superior Noise Reduction
For properties near busy roadways, airports, or train lines, secondary glazing is often more efficient than standard double glazing. When installed with a gap of 100mm to 150mm from the primary window, it can reduce external sound levels by as much as 80% (as much as 50 decibels).
