    • A vacuum insulation panel 2 comprises a first layer 4, an intermediate connecting layer 6 and a second layer 8. The first and second layers 4, 8 are each formed by a generally planar base 7, 9 having an internal side and an external side, and formations 12, 14 extending from the internal side of the base 7, 9. The intermediate connecting layer 6 comprises a generally planar base 11 with formations 16 extending generally perpendicularly from both sides corresponding to the formations 12 and 14 of the first and second layers 4, 8. The first layer is provided with an array of apertures 10 on the base 7. The formations are arranged such that they connect together to define substantially circular chambers 20 having outer cavities (22) around them within a matrix of generally square cells 30. Air is evacuated from the chambers 20 and cavities 22 through the apertures 10. By evacuating all possible areas of the vacuum insulation panel 2, heat loss and sound transmission is reduced to a minimum. The panel 2 is then sealed airtight by sealing the apertures 10.
