Patent applied for

The Roofbox K series modular roof kerbs are an offsite approach to forming kerb upstands around roof openings. It removes the need for formwork involved in creating concrete kerbs and associated labour costs involved with this process. The standard Roofbox K kerb upstands K1 - K6 are compatible with the Roofbox M roof cabinets M1 - M6. The K series kerbs feature a thermal break helping to improve efficiency and reduce potential condensation issues. The K series modular kerb system can also be used on timber and steel deck roofs providing a ready to fit option that is quickly installed. The benefits of using the Roofbox K system are as follows;
  • Significant cost savings avoiding concrete formwork
  • Reduced weight of roof structure
  • Can be used on timber or concrete roof deck structures

  • Made to size and supplied in kit form
  • Any height up to 600mm available
