Flashing with Additional Thermal Insulation EHV-AT Thermo, EHN-AT Thermo

The new universal EHT-AT Thermo flashing with an integrated insulation layer is designed for the installation of roof windows and helps ensure a tight connection with the roof covering while improving thermal insulation around the window. EHT-AT Thermo makes it possible to apply insulation of the window above the level of battens. To the inside of the flashing there is glued flexible insulating material which adheres tightly to the window frame constituting a thermally insulated frame that helps reduce heat transfer around the window. Below the level of the batten the window is insulated by a wool insulating kit XDP. The Thermo flashing helps improve the thermal performance of the window installation while helping to reduce thermal bridging and heat loss. The EHV-AT Thermo is a universal flashing designed for use with a wide range of roof coverings up to 90 mm in profile height and with compatible wooden and aluminium-clad plastic roof windows. It is applied as standard to individual windows in the slope of the roof. The flashing may also be used as module flashing for windows used in horizontal and vertical combinations or block groups available for installation of windows at a depth V (0 cm), on roofs with pitches between 15° and 90°.

Constituents of the Flashing

The EHV-AT Thermo is a universal flashing type, compatible with most types of roof coverings. The flashing is 22mm wider than standard and is made of four basic elements (bottom element, two sides elements and top element), each element is equipped with glued insulation material already made to size. The lower element has a long, wide aluminium plastic apron with an adhesive PVC fillet adhered to the underside. This allows the flashing to conform to the roof covering, supporting proper installation. The flashing is equipped with side sealing channels to protect against wind blown dust, leaves, rain and snow. In the set there is a weep flap to allow condensation to drain away from the window.
