How To Install a Velux Centre-Pivot Roof Window - Part 3

In this part of the installation, Mark shows how to fit the transverse drainage gutter, and the completed installation of the BDX insulation collar. Fixing it to the frame and battens and providing added protection to the roof window.

Most battens are nailed ..... so brilliant video except that part

Yeh no way you can simply just unscrew & slip the membrane bellow the bats on almost every real roof. But to be fair JJ's Velux videos are helpful info & they blow Velux's own videos out of the water any day.

Why does the slot for the drainage channel suddenly appear? There was no video for this part.

Do you have a video for this install for shingled roof?

We do not have a video demonstrating this window on a shingle roof.
