To Install You will Need:

• Corotherm Polycarbonate Sheet
• Corotherm Glazing Bar
• Corotherm Side Flashing
• Corotherm End Caps
• Corotherm Super Fixing Buttons
• Corotherm Breather Tape
• Corotherm Aluminium Sealing Tape
• Flashing Tape
• Wood Screws
• Silicon Lubricant Spray
• Low Modulus Neutral Cure Silicon Sealant

  • Starting at the downslope end, line up the ends of the cap and base and tap home with a rubber mallet until the edge seals have flattened against the sheet. Over driving the glazing bar cap may cause damage to sheets over time as they expand and contract with temperature changes, continue laying sheets and glazing bar caps in this way
  • Fitting the F-Profile. Finish the edge of the roof with an F-profile which can be secured to the rafter or barge board with screws. Fit the final glazing bar cap and complete the run of flashing
  • Fitting End Caps U-Profiles. To protect the breather tape, fit end caps or U-Profiles to the end of the sheet.
  • The U-Profile should be cut into sections to fit between rafters. Run a bead of sealant along the top edge of the end cap to prevent water penetration. Fit U-Profile into place with the drip detail leading into the gutter. Wipe off any excess sealant. Once the U-Profiles are in place, fit the glazing bar end caps. Finally, remove all protective film.
