Condensation protection for roof sheets with Borga DropStop™
When warm indoor air comes into contact with the cold steel sheets, the condensation fabric absorbs the precipitated drops and binds them to itself. Through a combination of ventilation and rising temperatures during the day, the moisture is transported away and the fabric dries out.
DropStop™ is used on uninsulated roofs and in cases where the insulation is installed below the light beam. It is the perfect solution in buildings with a regular, non-aggressive environment with average humidity.
The good reflecting properties of the light grey film maintain a good light level in the building. DropStop™ can be used in most well-ventilated buildings, factory premises with production operations during the day, as well as buildings with minimal heating.
DropStop™ is a composite fibre fabric that is glued onto the underside of the painted sheets. The fibre fabric comprises a mixture of natural and synthetic fibres, bound together with resin/binding agent.
