The Midtherm HTS 180mm (7") Twinwall Aluminium Flat Roof Plate is a metal flashing designed for flat roofs. This flashing slides over your twinwall flue once it has penetrated the roof and attaches to the flat roof from above. It has a high neck so you can weather proof your roof over the top of this item and it can be installed first. Considered a two-part flashing, the aluminium roof plate should be used with a storm collar. Available in a stainless steel finish as standard, this flashing does not have an internal diameter, however it is designed for use with 180mm twinwall with an outside diameter of 225mm. HTS is a Class 1. Twinwall chimney product manufactured by Midtherm Flue Systems right here in the UK and is suitable for use in both domestic and commercial applications.
