DRIPSTOP® Condensation Control

Keep condensation under control

Dripstop® – the original. Since 1996. The high-tech condensation control membrane effectively prevents damage caused by condensation dripping from uninsulated metal roofs.

Where there are large differences in temperature and humidity (e.g. day to night, indoor to outdoor), condensation forms on the underside of uninsulated metal roofs. High humidity amplifies this unwanted effect. Serious consequences can include corrosion or damage to the building structure, stored goods, and furnishings, along with negative effects on humans and animals resulting from dampness, mold, and mildew. Graber Post Buildings has the capability of applying this product to the underside of our ag-panel during the roll-forming process. When you receive your shipment, you are ready for installation!

Why choose Dripstop®

  • Meets the highest quality requirements
  • Efficient, easy, and safe to process
  • Quick to install
  • Meets all construction standards
  • Improve interior acoustics and reduce rain noise
  • Retains its full effectiveness throughout the roof’s life







Glazing Edge Treatment

We recommend heat treating the edges, eaves and end laps for a couple of reasons. By itself, DR!PSTOP is resistant to mold and mildew. But as dirty rain water runs down a roof, organic material can get trapped in the air pockets in the membrane. These organics provide food for mold and mildew to feed off of and grow from. Besides hurting the appearance, this mold and mildew can spread once it takes hold. This can accelerate the second problem which is wicking moisture in the building. Glazing prevents the wicking of moisture back up which can slow the evaporation process. On end laps (panels lapped over each other from ridge to eave typically found in wider buildings where a single panel length is not possible), heat treating keeps the water from wicking in as it runs down the roof during rain or snow. Holding water on a panel like this can void manufacturers’ warranties. To view the glazing instructions, click the link below.

**Please keep in mind it is important to ensure proper ventilation in order to turn the air over enough times to clear the moisture from the membrane. This will vary based on the construction, use and contents of each building.
