Description

Roof ventilation housing that allows daylight ingress and ventilation to improve wellbeing of building users.

Provides robustly weathered ventilation outlet for buildings that use cross-flow ventilation as a carbon reduction strategy.

Supplied in modular form complete with integral dampers, ready for over-glazing by others.

Off-site manufactured solution that reduces site-performed detailing, well-suited to design for manufacture and assembly (DfMA) projects.

Features and benefits:

  • Ability to allow increased daylight through roof for increased lighting efficiency and wellbeing.
  • Fabric-first approach; insulated and air-tight system improves thermal efficiency and enhances sustainability.
  • Robust weather defence system eliminates the risk of unwanted roof leaks due to poor detailing.
  • Pre-designed product with pre-determined free area ensures reliable performance.
  • Integral thermally broken damper allows natural ventilation effect to be controlled by the building management system (BMS).
  • Can be supplied complete with integral upstand to reduce the coordination, cost and time of site-formed upstands.
  • Offsite factory-controlled manufacture ensures a high level of quality is achieved with the detailing.
  • Polyester powder coating (PPC) provides a durable and long-lasting finish.
  • Pre-fitted with skirt flashing for simple roof interface detail.
  • Over-glazing by the project glazier enables single-source glazing.
