Sheerline’s Classic Window range now matches the double-glazing performance of their Prestige range, achieving a U-value of 1.4 W/(m²K). This is made possible by the addition of a Q-Lon self-adhesive glazing seal, which delivers ultra-low thermal transmittance and is discreetly positioned within the glazing chamber, beneath the glazed unit.
An independently verified U-value report details the specific test conditions used in the simulation and outlines the product’s performance when assessed against these parameters.
