Distance List of ventilation and the use of spacing list

摘要

The invention relates to a spacer bar (1) to the mounting ring and the valve between an outer casing (5) and an underlying structural member (7) in an outer construction of a building. Distance list includes a first abutment surface (4) for engagement with the outer casing, a second bearing surface (6) for engagement with the underlying structural member and at least the two end faces (8, 9) and at least two side surfaces (10, 11) is connected to the the contact surfaces. Distance list includes a first member (2) which can be fixed to the underlying lining by means of attachment means, and a second element (3) which is connected to the first element and which is designed as a ventable element, wherein an external air flow pass freely through the ventable element. At least one end face (8, 9) are prepared for interconnection with an end face of at least one second spacer bar. This ensures a better ventilation of the space between the outer skin and the underlying structure. Distance list is designed to be easy to handle and can be connected to the desired length.
