A U-value is a sum of the thermal resistances of the layers that make up an entire building element – for example, a roof, wall or floor. It also includes adjustments for any fixings or air gaps.
A U-value value shows, in units of W/m²K, the ability of an element to transmit heat from a warm space to a cold space in a building, and vice versa. The lower the U-value, the better insulated the building element.
A building element’s U-value is extremely important as there are certain standards that should be reached according to Building Regulations / Standards.
Therefore, to supply you with a U-value of a Kingspan insulation board in a floor, wall or roof, we need to know the full build-up of the element. If you have these details, follow the link below to request a U-value calculation from our expert team.
