Application

  • Insulated housing for mounting over a roof opening, with provisions for the weathering of ducts, pipes and cables as they exit a riser onto a roof.
  • Can be ordered with various base options to allow integration with most roof constructions, including cold, inverted and green roofs.

Description

Modular riser-weathering cabinet in two different heights, to suit roof openings of 1000 x 1500 mm.


Features and benefits:

  • Insulated aluminium construction provides enhanced thermal performance and helps to prevent condensation.
  • Polyester powder-coating (PPC) provides a durable finish.
  • Modular frame and panel system with removable lid allows easy access for the installation of services such as cables, pipes and ducts through the cabinet.
  • Engineered flashings provided to MEP services to ensure an effective and durable seal.
  • Can be retrofitted to existing kerb upstands and around existing services - allows flexible program sequencing.
  • Additional weathering hoods available for weathering multiple service penetrations as they pass through the side of the cabinet.
  • Supplied in kit form, easy to handle and suitable for fast assembly on site.
  • Compatible with the ROOFBOX® K modular kerb upstand system, which are available in a range of heights (to be specified separately). Alternatively, ROOFBOX® cabinets can be provided to suit site-formed kerbs.
