General

Make sure the clearly marked UV protected side of the sheet is facing outwards

Allow a minimum of 10° roof slope for water drainage

Use only low modulus neutral cure sealant and cross-linked butyl flashing tape

The flutes of the sheets must run from top to bottom of the slope, never from side to side

Sheets cannot be joined top to bottom

Cutting
Corotherm can be easily cut and will not crack or shatter. When cutting parallel to the flutes a sharp knife can be used but when cutting across the flutes a fine toothed saw is required. For cutting curves use a fine toothed jig saw.

Thermal Expansion
When installing Corotherm sheet it is important to allow a sufficient expansion gap at the top end of the sheet. When drilling fixing holes an expansion allowance of 3mm around all fixings is required. Do not fix or clamp sheets too tighly - leave room for thermal movement.

Cleaning
Corotherm can be easily and quickly washed with luke warm soapy water and a soft cloth or sponge. Do not use brushes or sharp objects and avoid any abrasives or cleaners of high alkaline nature.
