Sealants

Sealant strips

Sealant strips should be continuous along end laps and side laps, over and under ridge and eaves filler blocks and under barge flashings.

At sheet corners it is essential that the seals meet and do not leave a gap under the four way lap.

The sealant should be soft enough not to interfere with the fit of the sheet and sufficiently elastic to fill uneven gaps.
