Condensation
Condensation is a naturally occurring phenomenon in multi-wall sheets due to relative atmospheric humidity. Water vapor naturally form as droplets when they meets cooler surfaces. These droplets conjoin to form liquid in the multi-wall flutes or cells Multifoil AntiDUST® tape filter has a unique surface treatment that encourages rapid evacuation of collected condensation without compromising the size of the micromesh barrier that keeps other contaminants out of the cells. Condensation is also the lifeblood of algae and fungus as both need water to survive. The quicker it is removed the better. What we see with many competitors products is it simply does not drain thus creating conditions suited to algal reproduction.
Why not just seal the sheet ends to keep condensation out?
Considerable research revealed number of unusual phenomena associated with multi-wall panels in relation to condensation. The suggestion was made that both ends of multi-wall panels should be sealed to eliminate the condensation problem. This has been tried under practical conditions and it was evidently not a solution as condensate still built up within the flutes. Further analysis revealed that even if the multi-wall sheets were sealed under almost vacuum like conditions condensate would still appear.
It was concluded that the surface of the multi-wall behaved like a semi permeable membrane and water vapour could penetrate the panels. Thus the need for continuous drain-ability using AntiDUST® tape to offer an exit to condensate.

Six clear reasons to use AntiDUST® tape by Multifoil
All AntiDUST® tapes by Multifoil have been engineered to accomplish one goal: to keep your polycarbonate sheet clean and clear. This way you can enjoy all the benefits that a polycarbonate multiwall system has to offer.
The high end non-woven has been specially treated to make sure that condensation is gently guided outside. This way we ensure excellent draining.
Coated with a strong and durable adhesive, with outdoor resistance. Easy to apply and reliable. Engineered for polycarbonate application.
The filter gives perfect protection to filth and dirt, even in very small particles. Fungi, algae and insects stand no chance.
All multiwall sheets expand and contract due to its material qualities. All AntiDUST® tapes have been engineered to grow and shrink with the sheet. No more tearing or breaking of the tape.
Too much or too little ventilation, both isn’t good for the life time of the sheet. Our tape system provides the sufficient amount of ventilation.
Our specially treated high quality non-woven keeps particles >25µm out of the multiwall sheet and is anti-bacterial. Perfect protection.
