Bi-colour fillers available (Black on one side white on the other)
Sold as pairs (long flute and short flute foam fillers)
The "Long Flute" half of the pair will sit on top of the sheeting and fill the profile between the sheet and the ridge or abutment flashing
The "Short Flute" half of the pair is pinned below the sheet at the eaves line
Should be fitted whilst fixing sheets and flashings so that either the main fix screw pins the filler in place whilst fixing the sheets at the eaves, or so that the stitcher screw pins the filler down while adding ridge or abutment flashings
If used on a free standing mono pitched roof with no flashings two pairs of fillers will be required per sheet width so that a short flute half can be used at both the front and the back
