THERMALLY INSULATING BUILDING ELEMENT |
摘要 |
A building brick or block (1) has two opposed surfaces (2 and 3) which define a heat transfer area for the flow of heat along a path from one surface to the other. High aspect voids (4) are provided in the brick of block to form between 10 % and 90 % of the volume thereof, and satisfy the following requirements: (i) the notional thickness of each void is 6 millimetres or less; (ii) notional perpendiculars P to the voids lie within 30 DEG of the perpendiculars to the surfaces (2 and 3); (iii) at least 40 % of the heat transfer area has a minimum number of voids in series in the path of heat flow, which is equal to B/16 rounded up to the nearest integer, B being the distance in millimetres between the surfaces (2 and 3); (iv) at least 30 % of the heat transfer area has no voids in the path of heat flow. |
