The sealing system for aluminum window sills

How can aluminum window sills be effectively, quickly, and cost-efficiently sealed according to RAL/EnEV standards?

"With the new Kontex® Drainage System!"

Material Properties

  • "Fire resistance class B2

  • 1050 Pa watertightness

  • Air permeability class 4

  • Vapour-permeable SD ≤ 0.5

  • Resistant to alkalis

  • Resistant to microorganisms"

Good reasons for our drainage system:

  • Thermal expansion is compensated for.

  • "No leakage, no reworking!"

  • Prefabricated, accurately fitting corners!

  • "Significant time savings, more efficient construction process!"

  • Combination with KONTEX® input perforation & Power-Haft technology

  • "Optimal anchoring of the sealing membrane/building structure!"

  • Specially matched, vapor-permeable system!

  • "Thus, optimal ventilation of the building joint!"

  • For all common aluminum windowsills!

  • "One product for all, universally applicable!"

  • Permanently weatherproof construction!

  • "No rework or complaints!"

  • No cold bridges under the windowsill!

  • "Sustainable and compliant with RAL/EnEv!"
