Wood Cored Roll

Application

Used as the basis for lead sheet joints on flat roofing and pitched roofing as well as traditional 'hard' metal roofing.

Unsuitable for use on curved surfaces of small radii, such as semi-circular dormer tops.

Description

Premium Wood Cored Roll is used as the basis for lead sheet joints on flat roofing and pitched roofing as well as traditional 'hard' metal roofing. When there is the prospect of foot traffic, the wood cored roll joint is preferable to a hollow roll joint, as it is less prone to pressure damage. Premium Wood Cored Rolls are available in both treated and untreated condition. Treated wood has been subjected to high pressure impregnation of a wood preservative, which protects the wood against timber rotting fungi and wood destroying insects.


Features and benefits:

  • For lead sheet joints on flat or shallow pitched roofs.
  • Recommended for areas where ponding or storm flooding is possible.
  • Resistant to damage by foot traffic.
  • Forms aesthetically pleasing joint.
