Ideal for connecting \u003cstrong\u003eextractor fans, cooker hoods and tumble dryers\u003c\/strong\u003e to external wall outlets, it offers significant advantages over PVC flexible duct where \u003cstrong\u003ehigher temperatures\u003c\/strong\u003e are expected or where fire compliance is a consideration.
