All dimensions are nominal

*The 50mm and 65mm DriTherm 37 products are manufactured to 0.035W/m²K and 0.036W/m²K lambda respectively. This higher specification allows the thinner 50mm and 65mm materials to achieve a robustness normally associated with thicker materials and so allows for easier installation.
