Our double-glazed units achieve U-values of 1.1, while our triple-glazed units reach U-values as low as 0.5 (R=2). The R-value is calculated as R=1/U, highlighting the impressive insulation properties of our glazing solutions.
Our triple-glazed units achieve up to 74% light transmission, while double-glazed units reach up to 82%. Despite their high insulation values, these units maintain excellent levels of natural light, creating bright and welcoming interiors.
