The Schiedel ICID Adaptor to Single Skin is a starting component designed to connect Prima Smooth single skin flue to Schiedel ICID Plus twin wall pipe. Available for 125mm (5″) and 150mm (6″) internal flue diameters, it provides the transition point between the two flue systems.
Its purpose is specific: where a flue route begins in Prima Smooth and needs to change to insulated ICID Plus twin wall chimney, this adaptor provides the corresponding system connection.
Two diameter options are available, allowing the adaptor to be selected to match either a 125mm (5″) or 150mm (6″) flue system. The size should correspond with the adjoining components being connected.
The adaptor is listed within the Schiedel ICID Starting Components range, reflecting its role at the transition into the ICID twin wall section rather than as a standard straight chimney length.
The wider ICID Plus system is designed with a load-bearing outer case and an inner liner that is free to expand independently. This arrangement allows thermal expansion to be accommodated within each joint of the system.

Expert Insight
This adaptor should not be confused with a general ICID pipe connector. Its specific purpose is to create the transition from Prima Smooth single skin flue to ICID Plus twin wall, making the correct system and diameter particularly important when specifying the component.
Suitability
The Schiedel ICID Adaptor to Single Skin is suited to chimney installations where Prima Smooth flue transitions into an ICID Plus twin wall chimney system, with options for 125mm and 150mm internal flue diameters.
Installation / Technical Notes
This component is designed specifically to convert from Prima Smooth to Schiedel ICID Plus twin wall pipe. Select either the 125mm (5″) or 150mm (6″) version to match the internal flue diameter of the adjoining system.
