Service Temperature

FRF states an operating temperature of 780°C when tested according to DIN 52271 at 80 mm thickness and 100 kg/m³ density.

The Rockwool fibres can withstand temperatures above 1000°C without melting.

For foil-faced products, the maximum service temperature of the facing and adhesive may be lower than the insulation itself, so the complete insulation system should be selected according to project requirements.

HVAC Duct Installation Guidance

For foil-faced Rockwool Blanket used on HVAC ductwork:

• Make sure the duct surface is clean and dry before installation.
• Cut the insulation accurately to suit the duct dimensions.
• Fit the blanket closely without unnecessary gaps.
• Use suitable insulation pins or mechanical fixing where required by the approved project specification.
• Seal foil-facing joints with suitable aluminium foil tape.
• Make sure corners, joints and penetrations are properly sealed.
• Follow the approved project or consultant installation requirements for final fixing and pin spacing.

Note: Exact pin spacing and fixing details should follow the approved HVAC insulation system or project specification.
