FRAME INSULATION COLLAR
The frame insulation collar from installation set BDX 2000 consists
of four long pieces of polyethylene foam fitted on steel rails. As-
semble the rails as a frame then position on the battens around
the roof opening before installing the window. It is then fixed along
with the installation brackets of the window.
If the free distance between the rafters is not sucient, it may be
necessary to adjust the frame insulation collar to ensure correct
positioning. Adjust by tearing along the slit on the sides.
The frame insulation collar allows for the installation of VELUX
linings.
When using on-site linings the top and bottom parts of the frame
insulation collar may need to be adjusted by tearing along the slit
on the sides.
