NedZink Batten Roll
Application

  • Designed for covering of large and small inclined and vertical surfaces.
  • Can be used on ventilated and damp proof facades.

Description

The roll cap roof system is suitable for large and small roofs with a pitch of the roof of at least 3°, preferably >7°, and as facade cladding. The standard NedZink roll cap roof consists of zinc bays with upstands on both sides and separated by trapezoidal wood rolls. Zinc caps are used to cover these wood rolls. This gives the roll cap its characteristic and robust appearance.

The rolls have a trapezoidal cross section with a width of 40–50 mm and a height of 60 mm. The watertight finishing between roof bays and wood rolls is obtained by a covering profile (roll capping).

NedZink produces titanium zinc in accordance with EN 988, an alloy based on electrolytically refined zinc with a minimum purity of 99.995% Zn (Z1 in accordance with EN 1179) with small additions of the alloy elements copper, titanium and aluminium.

Roofing or facade cladding in NedZink titanium zinc protects a building for up to 70 or even 150 years. An environmental product declaration with ECO platform label for NedZink NATUREL, NedZink NEO and NedZink NOIR are available, consult literature for details.
