EHV-AT Thermo

The EHV‑AT Thermo flashing with additional insulation ensures a tight and thermally efficient connection between the roof window and the roof structure. It enables insulation of the window above the batten level. The flashing is equipped with an internally bonded flexible insulation material that closely adheres to the window frame, forming a continuous thermal insulation layer after installation. The insulation material features very good thermal performance (low thermal conductivity, λ). Below the batten level, additional insulation is provided by natural sheep wool included in a separate product – the XDP insulation set. The Thermo flashing improves the thermal performance of the window, reducing the heat transfer coefficient by up to 15% (depending on the window type), while minimizsng the risk of thermal bridging and heat loss.
