Ridgeline is a New Zealand made linear timber fin system designed for application over plasterboard wall and ceiling linings without the need for secondary backing boards, which allows fins to be randomly placed for greater design freedom.

The hidden fixing system prevents unsightly screw or nails being visible for a clean finish, and the bottom quirk negative detail accommodates for slight variations in wall / ceiling lining flatness to present clean sight lines to the fin / lining interface. The aluminium mounting system helps keep fins straight and true.

Key Features
  • Provides an attractive linear aesthetic to plain plasterboard surfaces
  • Can be mounted over wall papered or painted surfaces
  • Concealed fixing system
  • Fins can be from solid or laminated timber, laminated FR MDF and finished in a range of stains, paint coatings
