The Magnetglaze Sash Jointing Kit is a heavy-duty secondary glazing jointing system designed for use with Magnetglaze and Magnetglaze Pro panels. Ideal for large windows and draughty sash windows, it allows glazing panels to be joined securely, creating a practical multi-panel solution that improves handling while maintaining excellent thermal performance. Designed to divide larger glazing panels into more manageable sections, the kit makes panels lighter, easier to install, remove, and store, while also providing more convenient access to the primary window for cleaning and ventilation. It is particularly well suited to traditional sash windows and oversized window openings where a single secondary glazing panel would be difficult to handle. Manufactured from high-quality, durable materials, the Magnetglaze Sash Jointing Kit provides a strong, reliable connection between panels while maintaining the effectiveness of the secondary glazing system. Suitable for both DIY enthusiasts and professional installers, it offers a long-lasting, low-maintenance solution for improving the practicality, insulation, and overall performance of Magnetglaze and Magnetglaze Pro secondary glazing installations.
