445 Double Glazed Disc

Product Details

The 445mm Clear Double Glazed Disc is a genuine Solatube part compatible with 400mm Solatube skylight systems, this diffuser uses a double-glazed acrylic design to improve insulation while maintaining excellent natural light transmission.

Constructed from high-impact UV-stabilised acrylic, it provides exceptional clarity while resisting yellowing, impacts, and long-term environmental wear. The clear double-glazed construction helps reduce heat transfer and minimise convection, improving comfort without reducing daylight performance.
