The twinwall sealer and dust tape combo pack contains one 11m roll of aluminium sealer tape, and one 11m roll of dust tape.

The sealer tape (silver) goes at the high end of the sheet to prevent water getting into the flutes.

The anti-dust tape (blue) goes at the lower end. This allows any moisture that does get into the sheet, to run out. It also prevents dust, dirt, sediment and insects from getting in the lower end.

It is essential to use polycarbonate end caps in conjunction with the Laserlite twinwall anti-dust tape, to prevent the adhesive in the tape from drying up (unless tape is encapsulated by a glazing system).
