Flashings for changing window installation angle ESA, EZA, EHA. EA flashing is ideal for a flush fit of the window with low pitch roof coverings of 10 or more. It enables the installation angle to be raised by an additional 10. This flashing is used in attics and lofts to provide additional space. It is commonly used to install single windows in roof slopes. It is also available in modules for horizontal joining the windows. Three flashings are available, use of which is dependent on the roof covering: ESA flashing is a flat covering with a profile depthof 10 mm (2x5 mm) for use with slates and similarly flat roof coverings. EZA flashing is a profiled covering up to 45mm, for use with roof tiles and profiled sheeting. EHA flashing is a profiled covering up to 90mm, for use with roof tiles, corrugated and deep profiled sheeting. Can be used on roofs with pitches between 10 and 75. Constituents of the flashing: The flashing is made up of four elements. The lower element is fitted to the roofing material. The upper and side elements are profiled in away to create an insulated are abetween flashing and side element, insulating the elevated elements. EZA and EHA flashings come with weep flaps, to allow condensation to drain away from the window, as well as side sealing channels to protect against wind blown dust, leaves, rain and snow.
