Rain collar

Rain collar

Rain collars, also known as storm collars, are positioned between the roof flashing and the final fitted length. It is important to leave a small gap between the rain collar and both components. As it covers an area of approximately 10 cm around the chimney pipe, it helps prevent rainwater from entering.

Important: The dimensions refer to the chimney's internal diameter. Twin-wall stainless steel chimneys have 50 millimetres of insulation. To determine the exact dimensions, add this (+ 50 mm) to the internal diameter.
