The Magnetglaze – 12.5mm Wide – Magnetic Glazing is a simple, effective secondary glazing system designed to improve thermal insulation, reduce draughts, minimise condensation, and help lower external noise. Ideal for homes, offices, listed buildings, and conservation properties, it provides a removable secondary glazing solution without permanently altering existing window frames.

The 12.5mm wide magnetic system provides a secure hold while maintaining a clean, discreet appearance, making it ideal for seasonal insulation or year-round secondary glazing. For a complete installation, Magnetglaze Sash can be used to join plastic glazing sheets, while Magnetglaze Finishing Trim creates a smart, frame-like border around the panel for a professional finish. Available in a range of lengths, the Magnetglaze – 12.5mm Wide – Magnetic Glazing is suitable for both DIY enthusiasts and professional installers, offering a durable, low-maintenance solution for improving window insulation and energy efficiency.
