Replacement of roof window

A. REPLACING LINING

Install the roof window following standard procedure and with a

standard ﬂashing.

VELUX installation products BDX, BFX and BBX should be used if

possible.

Note! When using VELUX linings while maintaining the old window

opening, the lining must be specially adjusted (see page 88).

B. KEEPING LINING BUT REDUCING DEPTH

If the window to be replaced is from before October 1998, the new

window will be installed deeper in the roof than the old window.

This means that the lining must be reduced by 27 mm on all sides.

Position frame in the lining and secure with installation brackets.

Fit standard ﬂashing following standard procedure. The lining ﬁts

at the sides but it is necessary to ﬁt facings (a) at top and bottom.

VELUX installation products BDX, BFX should be used if possible.

The frame insulation collar from installation set BDX may have to

be adjusted at the top or bottom.
