Question 1

What is secondary glazing?

Secondary Glazing Noise Reduction · Accepted Answer

Secondary glazing is an additional window panel installed on the inside of your existing windows. Unlike replacement double glazing, it preserves your original windows while providing significant improvements in noise reduction, thermal insulation, and security.

Question 2

How much noise reduction can secondary glazing provide?

Secondary Glazing Noise Reduction · Accepted Answer

Professional secondary glazing typically achieves 70-80% noise reduction, which equates to a reduction of 35-45 decibels. This transforms busy, noisy environments into peaceful sanctuaries. The exact reduction depends on factors like gap size, glass thickness, and seal quality.

Question 3

Is secondary glazing suitable for listed buildings?

Secondary Glazing Noise Reduction · Accepted Answer

Yes, secondary glazing is ideal for listed and conservation area properties as it's installed internally without altering the external appearance. It's fully reversible and often the only approved solution for heritage properties. We have extensive experience working with conservation officers.

Question 4

How long does secondary glazing last?

Secondary Glazing Noise Reduction · Accepted Answer

Quality secondary glazing systems last 25+ years with minimal maintenance. We provide a comprehensive 25-year warranty on all installations, covering materials and workmanship.

Question 5

What is the cost of secondary glazing installation?

Secondary Glazing Noise Reduction · Accepted Answer

Residential secondary glazing typically starts from £450 per window. The exact cost depends on window size, opening style, glass specifications, and specific requirements. We offer free on-site assessments and detailed quotes with no obligation.

Question 6

Is secondary glazing worth the investment?

Secondary Glazing Noise Reduction · Accepted Answer

Yes, secondary glazing offers excellent value. Beyond immediate noise reduction and comfort improvements, you'll benefit from reduced heating bills (up to 10% savings), increased property value, and improved security. Most customers recover their investment within 5-7 years through energy savings alone.

Question 7

Question 9

Is the installation process disruptive?

Secondary Glazing Noise Reduction · Accepted Answer

Installation is minimally disruptive. Our experienced installers work cleanly and efficiently, with most rooms only requiring access for a few hours. There's no external scaffolding, no mess, and no structural changes required.

Question 10

Do I need to prepare anything before installation?

Secondary Glazing Noise Reduction · Accepted Answer

Simply clear the area around your windows of ornaments and furniture. Our team will protect your flooring and furnishings. We'll handle everything else, including final cleaning after installation.

Question 11

What type of glass do you use?

Secondary Glazing Noise Reduction · Accepted Answer

We use high-performance acoustic glass, typically 6.4mm or 10.8mm laminated glass depending on noise levels. For maximum performance, we can specify acoustic-grade laminated glass with specialist interlayers designed specifically for noise reduction.

Question 12

What is the optimal gap between primary and secondary glazing?

Secondary Glazing Noise Reduction · Accepted Answer

For optimal noise reduction, we recommend a gap of 100-150mm between the primary and secondary glazing. This air gap is crucial for sound attenuation. Smaller gaps are less effective for low-frequency noise.

Question 13

Will secondary glazing cause condensation?

Secondary Glazing Noise Reduction · Accepted Answer

When properly installed with good seals on both the primary and secondary units, condensation is rare. We ensure adequate ventilation and high-quality sealing to prevent moisture issues. Any existing condensation problems are typically improved.

Question 14

Can secondary glazing be installed on any window type?

Yes, we can install secondary glazing on virtually any window type including sash windows, casement windows, bay windows, and skylights. We custom-manufacture each unit to fit your specific windows perfectly.

Question 15

How do I clean secondary glazing?

Secondary Glazing Noise Reduction · Accepted Answer

Clean your secondary glazing with a soft cloth and standard glass cleaner. Most of our systems are designed for easy removal, allowing you to clean both sides of the primary and secondary glazing. Annual cleaning is usually sufficient.

Question 16

What maintenance is required?
