WebWall 1 with U-Value of 0.3 W/m2 K will lose heat at half the rate of Wall 2 which has a U-Value of 0.6 W/m2 K . So, the LOWER the U-Value, the BETTER. The lower the u-value the more efficient the construction is at keeping heat flow through the structure to a minimum. Are U-values important in the Building Regulations Approved Document Part L? WebNov 13, 2013 · The best insulating materials have a U-value of close to zero – the lower the better. Building regulations currently stipulate that for a new building, the elements must have maximum U-values as follows: Wall – 0.3 W/m 2 k. Roof – 0.15 W/m 2 k. Windows – 1.6 W/m 2 k. So in each section below we are going to examine each of the different ...
WebJul 30, 2024 · A material’s thermal resistance depends on its thickness (d) and its thermal conductivity (’λ-value’ or sometimes ‘k-value’). Thickness – Cool. Got it. Intuitively, the thicker a material is, the more insulating it is. Thermal conductivity, however, is a bit trickier. There are tons of resources out there that can tell you how this ...

WebMar 15, 2024 · The lambda value, also portrayed as ‘K-value’ or ‘λ-value’, measures a product’s thermal conductivity in units of W/mK. Good insulation will have as low a lambda value as possible to reduce heat loss. For example, our lower lambda products each have a lambda value of 0.019 W/mK across all thicknesses. What about an R-value?
