Loft insulation is rated based on its thermal conductivity, typically measured in Watts per meter Kelvin (W/mK). This rating, known as the ‘U-value’, determines the effectiveness of the insulation material in preventing heat loss. The lower the U-value, the better the material is at insulating. For instance, a U-value of 0.040W/mK indicates better insulating properties than a U-value of 0.044W/mK.

In selecting the right insulation for your loft, it’s important to consider this rating alongside other factors like thickness and material type. At Workplace Interior Shop, our range of loft insulation products includes detailed specifications, including U-values, to help you make an informed choice.
