The DR!PSTOP anti-condensation coating can absorb over 830 g of water per square metre. DR!PSTOP is available for the BTD35; BTD 45, 900 and BTD55 box profile sheets.
Other advantages include: 

  • Water-washable
  • High anti-bacterial resistance
  • High fire resistance: Class A2-s1, d0 (EN 13501-1)
  • Enhanced anti-corrosion protection
  • Noise comfort (dampens the sounds of rainfall, and mechanical noise inside the building)
