EcoStar Roof Tiles

Viking EcoStar Roofing Tiles emulate the look and durability of natural slate at half the weight. The tiles are composed of 80% recycled polymers and are installed over a plywood or Viking SuperStrand sarking substrate.

The unique formulation of EcoStar tiles renders several advantages over slate roofing whilst still offering natural slate's timeless look and longevity.

Key Features
  • Composed of 80% post-industrial recycled rubber and plastics from the likes of old car bumpers; door mouldings; radiator hoses; and off-cuts from the manufacture of disposable diapers;
  • Tiles are flexible and won't crack and have high impact resistance;
  • Over 45 colour and profile combinations;
  • Assessed by the independent Underwriters Laboratory (U.L.), assessing their collective resistance to: wind uplift; UV; and impact (holds the highest impact rating a construction product can);
  • Formulated to resist extreme temperature variations;
  • 175kmph wind rating (officially classified as 'Very High');
  • The structural integrity of the EcoStar system is enhanced through the installation of a timber sarking substrate onto which it is securely fastened. The roof system (including substrate) is approximately half the weight of a natural slate roof and yet its durable and light-weight substrate braces the entire building; negating the need for extra structural requirements for heavy weight roofing materials.
