Velux Recessed Flashings EDN / EDJ

Recessed flashings provide a sleek and streamlined finishas the roof windowis installed deeperinto the roof structure, meaning that less of the roof window protudes above the roofline. We reccomend BDX insulation collar and BFX underfelt collar, included in EDN and EDJ 2000, for optimum energy efficiency. Recessed installation height - install the brackets at the sides of the roof window frame, at the blue line level.
