    Frequently Asked Questions

    Get answers to common questions about secondary glazing installation and benefits.

    How much noise reduction can I expect from secondary glazing?

    Our secondary glazing systems provide 70-80% noise reduction, with measurements showing 45-54 dB reduction in real-world installations. This is significantly better than double glazing alone.

    Can secondary glazing be installed in listed buildings?

    Yes, secondary glazing is ideal for listed and heritage buildings as it doesn't alter the original windows. It's conservation-approved and typically doesn't require planning permission.

    How much does secondary glazing cost?

    Secondary glazing costs approximately 50-75% less than replacing windows with double glazing. Prices typically range from £200-600 per square meter depending on specifications.

    How long does installation take?

    Most residential installations are completed within 1-2 days. We work efficiently with minimal disruption to your daily routine.

    Will secondary glazing affect the appearance of my windows?

    Our secondary glazing is designed to be virtually invisible from the outside and minimally intrusive from the inside. We use slim aluminium frames that complement existing window styles.

    Does secondary glazing help with thermal insulation?

    Absolutely. Secondary glazing creates an insulating air gap that significantly reduces heat loss, potentially cutting heating bills by up to 10%. It also eliminates cold draughts and condensation.
