10M x 45mm Breather (Vent) Tape for 25mm Polycarbonate Sheets

Sold in 10M rolls and used for sealing the ends of your polycarbonate sheets, vent tape (also known as breather tape) is used at the bottom ends of sheets (gutter end). This tape allows the air to circulate through and around the sheets, helping to stop sheets from developing condensation inside.

The tape can be used on the top end of the sheets as well, but this is normally covered with aluminium tape which is cheaper. 

The size stated is the thickness of sheet these roll is use on and not the width of the tape.
