How to measure?
Measure the Outside Diameter (OD)
Pipe insulation sizes refer to the outside diameter of the pipe — not the bore (internal diameter).

|←— OD —→|
Wrap a tape measure around the pipe, divide by π (3.14) to get the OD. Or use calipers across the outside of the pipe directly.

ROCKWOOL DuctWrap Foil-Faced Stone Wool Insulation

ROCKWOOL DuctWrap is a flexible stone wool insulation roll faced with reinforced aluminium foil. It is designed primarily for thermal insulation of circular ductwork and water storage tanks, and can also contribute acoustic absorption in building-services applications.

  • Can be specified in accordance with BS 5422:2023 where appropriate for the application

Applications

Use DuctWrap for circular HVAC ductwork, warm-air and extract ducts, and water storage tanks where flexible foil-faced stone wool insulation is required. For square and rectangular ductwork, ROCKWOOL DuctSlab is the purpose-designed product.

Installation

Fit the insulation closely to the substrate and seal foil-facing joints as required by the system design. Insulation thickness should be selected according to service temperature, ambient conditions and the required thermal or condensation-control performance.
