Due to high sheet metal conductivity the condensate occurs on the inner side of metal roof covering and starts merging into droplets. In time these droplets begin dripping from the inner side of metal roof into the room and consequently cause damage.

Metal roof tiles with affixed ATIDRIP membrane which absorbs condensate and prevents dripping.

During condensation ATIDRIP can absorb up to 1000ml/m2 condensate. At natural ventilation and at higher daily temperature the condensation between membrane fibres gets dry.

Additionally to condensate control ATIDRIP features other advantages:

• Faster process of roof covering – lower costs.
• It replaces the function of vapour-permeable film.
• Adhesive additionally protects the sheet metal surface against corrosion.
• Decreases noise created in rain by raindrops.
• Material is resistant to bacteria.
• Incombustibility (A2).

Antidrip is a new type of needle punched polyester non-woven fabric, produced by amending processing and special technology. From the production processing, the technical requirements of Antidrip are much higher than the ordinary non-woven fabric; At the same time, from the quality of view, Antidrip also has the functional characteristics that other non-woven fabrics do not have, with high moisture absorption, strong drainage and high flame retardancy.

Antidrip has very high physical and chemical properties. It can burden several hundred kilograms of tension without breaking up. Antidrip is self- adhesive. Its use hot-melt, flame retardant ，and environment-friendly glue. It’s very sticky and no smell.

Antidrip can quickly bring the vapor outside the building avoid breeding mold, effectively improve the energy efficiency of the building structure, keep it in the best use state, and solve the moisture-proof and human living health perfectly. It is a new and environment-friendly energy-saving material.

Antidrip is a cost-effective solution that can replace insulation materials and humidifiers to protect roof systems and buildings from the interference of condensate. The base material is specially made of self-adhesive non-woven fabric. From roll forming equipment fitted to the back of the steel plate. By absorbing the Vapor inside of the steel roof, drained the water into the bottom of the slope and evaporates the water content in the non-woven fabric by natural ventilation. Thus it could replace the insulation material (PU foamed, rock wool. EPS, XPS, PIR). The user can easily cut, fit and using fully automated equipment to apply the non-woven fabric to the color steel sheet on the roof. It must have ventilated in the building.
