WarmRoof - a waterproof roofing insulation system

RJJ_viking-aerial_180418_042.jpg

A warm roof (for low slope roofs) is “a roof where the insulation is installed on top of the roof structure” i.e. insulated from the outside of the building.

One if the benefits of a thermally efficient warm roof is the transfer of a building's dew point to the outside. This prevents internal dampness of structural materials and negates the need for vents that would normally allow air to escape.

A Viking WarmRoof system is BRANZ appraised (Appraisal No. 713), insuring it meets New Zealand building code requirements.

Components of a Viking WarmRoof system:

  • Vapour barrier (for cool stores and regions with extreme climatic variances)

  • Kingspan Polyiso insulation panel (including tapered)

  • Any of Viking’s sheet membrane systems

A Viking WarmRoof system is perfect as an overlay option on any existing roof - including metal
