The Superglaze – Screw Down Glazing is a durable secondary glazing system designed to provide a secure, professional installation while improving thermal insulation, draught reduction, condensation control, and noise reduction. Ideal for homes, offices, schools, listed buildings, and commercial properties, it offers an effective way to upgrade existing windows without replacing the original frames. The system features rigid PVC glazing channels that push securely onto the edge of the glazing sheet before being fixed to the window surround with screws. Once installed, a clip-on cover strip neatly conceals the fixings, creating a clean, professional finish while protecting the screws from view. Manufactured from high-quality rigid PVC, the Superglaze – Screw Down Glazing is lightweight, durable, and easy to install, making it suitable for both DIY enthusiasts and professional installers. It provides a strong, long-lasting glazing solution that enhances window performance by reducing heat loss, limiting outside noise, and improving energy efficiency, while maintaining a neat, low-maintenance appearance.
