ISOTHERM is safe and easy to install, will not sag in hollow wall frame structures and will not support the spread of flame.

Cut the ISOTHERM to size or slightly bigger than the frame size depending on the thickness of product used.

ISOTHERM is available in 40, 50, 75 and 100mm. However, we recommend no less than 50mm for exterior as well as interior walls.

Variable widths are available, but a minimum of 50mm is recommended.

To install:

  • Position ISOTHERM correctly. Position closely to the cladding and ensure a snug fit.
  • Ensure continuous insulation. Carefully butt the ends of the rolls or lap to ensure maximum effectiveness.
  • Ensure that the ISOTHERM is positioned behind cables, conduits and plug points, leaving them exposed.
  • Do not waste off-cuts. Use them wisely by filling in gaps, crevices and corners.
