<p>A lightweight, partially evacuated load-supporting insulation panel (1) comprising an outer gas-impermeable envelope (2) and an inner gas-permeable envelope (3). The inner envelope is filled with a mixture of coarse gas-permeable granules (4) and fine gas-permeable particles (5), void spaces formed within and between said granules and particles containing a gas of low thermal conductivity. An intermediate gas-impermeable envelope (7) may also be used.</p> |
