A U‐Value is the measurement of a material’s insulation effectiveness. Thermal performance is measured by the amount of heat loss. We refer to this as a U‐Value. When you are looking at how thermally efficient something is, the lower the U‐Value, the better the thermal performance is.

Usually, most solid conservatory roof U‐Values are 1.0 W/m2 or less, this means they have excellent insulation properties that will keep the heat in colder months and keep the room nice and cool during the summer.
