As from October 2020 every poultry unit that is under the Red Tractor scheme will require a minimum of 3% of window space governed by their floor area.

Powell & Co can install windows into any of your poultry units, old or new, timber posted or clear span, minerit lined or steel lined, with an option on design to suit the age and structure of your units.

Options can include:

  • UPVC Framed Windows:
  • 28mm Double glazed, toughened glass, obscured to grade 2, argon filled.
  • Polycarbonate twin wall infill – various thickness.
  • Glass has a U – Value of 1.5.
  • External composite panel shut off doors will either be 25mm or 44mm thick, depending on your wall thickness, operated


  • Wooden Frames:
  • Polycarbonate twin wall infill – various thickness.
  • An external sliding blind operated on a manual hand winch (can also be automated on a pulley system).
  • External shut off door (marine plywood) operated manually on hooks and chains.
  • A sliding blind sandwiched between the internal and external polycarbonate linings within the wooden framework.
