Anti-Condensation Liner

This simple method of rolling a flock material to the underside of our box profile and corrugated sheets reduces the risk of condensation* and drastically cuts the cost associated with full insulated panels.

* Anti condensation liner requires good air circulation around the sheet to allow water held by the liner to evaporate away. We recommend that eaves and ridges are left open but if you insist on using foam fillers you should notch them out to allow air circulation. Minimum recommended roof pitch is 10° for liner to be fully effective.

If your roof does not have sufficient ventilation and pitch you may find that in some instances the anti condensation liner may hold too much water and drip, especially in extreme temperatures (e.g. cold mornings)

Adding anti condensation liner to our roof sheets is a cost effective method of handling condensation problems in many buildings. If you believe that there is a chance of condensation we would highly recommend Dripstop anti condensation liner as an extremely effective solution.

Controlling condensation

When the temperature and humidity conditions in the building reach dew point, moisture will condense on the underside of an uninsulated metal roof sheet. If there is a lot of condensation, water droplets will form and start to fall. The traditional method for eliminating build up of condensation is to insulate the roof so that the temperature on the metal sheet never reaches the dew point.

Drip Stop anti condensation liner is pre rolled onto the sheet and will provide a much more cost effective solution than full roof insulation.

Advantages of anti condensation lined sheets

  • Save up to 25% on traditional solutions
  • Durability (Drip Stop anti-condensation felt liner is not susceptible to ripping, tearing or deterioration like standard insulation and vapor barriers are)
  • Easy to clean (with hose or pressure washers)

The Drip Stop solution

Roofing sheets lined with Drip Stop anti-condensation material provide a medium for trapping this moisture in the specially designed pockets formed in the membrane. Drip Stop holds the moisture until conditions go back below the dew point. The moisture is then released back into the air in the form of normal humidity.

Drip Stop is self adhesive felt liner that is applied to our sheets during the roll forming process. This means that the sheets will arrive with you with Drip Stop already in place, ready to be installed immediately. Your sheets are then installed as normal.
