How good is secondary glazing at reducing noise?

Secondary 1

Secondary glazing has a reputation for considerably reducing external noise from leaking into the home. Our secondary glazing has undergone sound tests, which measures sound intensity in decibels (dB) to assess how well it reduces noise pollution. The higher the dB value, the louder the noise in the home. An example of the outcomes of the test is our 4mm glass at 39db, which reduced noise by an astonishing 65%.

Is secondary glazing effective?

Sound pollution isn’t the issue some homeowners have with older windows, energy efficiency and security are also compromised by keeping the unique character of these classic windows. Secondary glazing is an effective and popular choice with homeowners living in a listed building or conservation area, or just love the look of their existing windows. This glazing option has a variety of benefits, including:

Retaining more of a home’s valuable heat and saving money on energy bills

Draughts, cold spots and high energy bills can be a headache for homeowners with older windows. Secondary windows retain more of precious heat and eliminate draughts to maintain a more consistent temperature in the home, helping to reduce the cost of energy bills and the home’s overall carbon footprint.
