• The 25cm diameter – the smallest available diameter – offers maximum flexibility in applications and is ideally suited for use in buildings with limited space or architectural restrictions, such as listed buildings.
• Within the 25 cm segment, this product offers the best mix of thermal insulation, acoustic performance, light output, and price. Looking for an optimal balance within this size range? Then this is the right choice. If the application is technically suitable for a larger diameter, we recommend the 35 cm version. It delivers up to twice the light output of the 25 cm version.
