S3 Tilting Spring Balance Thermal Data
Barnsdale's are committed to developing thermally efficient windows using traditional profiles and double glazing units. This means that all high performance products do not need a sacrifice in aesthetic appearance. For more information on the thermal performance of our window you can contact us or see our Thermal Performance Specification Guide.
We now offer as standard a full U-Value report with every order, which details the U value of each window and its frontal area, simplifying the data required to calculate whole building energy efficiency.
