What is Secondary Glazing?
Secondary glazing refers to the addition of a second layer of glazing-- typically a transparent sheet of glass or plastic-- placed inside or outside of an existing window. This additional layer acts as a barrier to sound while also improving thermal insulation. Secondary glazing is especially popular in older homes where replacing initial single-glazed windows might not be practical or desirable for visual factors.
How Secondary Glazing Reduces Noise
Secondary glazing lowers noise through 2 primary mechanisms:
Increased Air Gap: By developing an air area between the two layers of glazing, secondary glazing improves sound insulation. The air gap serves as a buffer, soaking up sound waves before they can go through to the interior area.
Damping Effect: Secondary glazing includes mass to the window system. The combination of mass and the air space helps to moisten sound vibrations, leading to additional noise attenuation.
Key Benefits of Secondary Glazing
| Benefit | Description |
|---|---|

| Glazing Type | Common Thickness | STC Rating * | Noise Reduction Capability |
|---|---|---|---|
| Single Glass | 4-6 mm | 28-32 dB | Low |
| Laminated Glass | 6-12 mm | 32-38 dB | Moderate |
| Double Glazing | 12-24 mm | 34-42 dB | Good |
| Triple Glazing | 24-30 mm | 38-45 dB | Exceptional |
| Acrylic/Perspex | 3-5 mm | 25-30 dB | Low to Moderate |
* STC = Sound Transmission Class: A greater STC ranking shows higher noise insulation abilities.

Frame Type: Consider the type of frame used for secondary glazing. Options like uPVC, wood, or aluminum effect not just aesthetics however also total noise insulation.
Air Gap Size: The efficiency of secondary glazing increases with the width of the air space. A space of 100mm or more is perfect for achieving optimum noise reduction.
Sealing: Ensure all edges and joints are well-sealed to avoid sound infiltration. High-quality seals can considerably boost the overall efficiency.
