  • A 'roof in a box' solution - nice and convenient
  • Free-spanning, with integral aluminium strengthening bars - perfect for homes or large commercial properties
  • Built-in sun diffusion, plus excellent light transmission properties
    Unique controllable ventilation system
  • Clean, uninterrupted lines - ideal for a contemporary Mediterranean-style conservatory

  • Available in a variable pitch of 2 1/2 degrees min. to 10 degrees max
    A free span of upto 4m without the need for a goal post

The combination of these features ensures an interior climate that is cool in summer and warm in winter - the perfect conservatory!

Not only this, but for your peace of mind Ultralite 500 comes with:

  • 'Life expectancy of at least 25 years' - BBA-certified
    Fire safety ratings after stringent tests
  • U-Value of 1.9
  • 10-year manufacturer's warranty (white only)




Ultralite 500 has been put through extensive accelerated weathering tests to simulate the worst of British weathering conditions. The tests were the equivalent of a 10 year 'live' period on the roof and have given Ultraframe the confidence to offer a 10 year warranty (on white) in addition to the BBA's assessment of at least 25 years life expectancy.
