| A hard plastic mandrel with an "arrow-like" leg design facilitating reverse bind. Available in 4 different lengths matching the thickness of the insulation material. Galvanizing depth necessary for concrete is min. 5 cm. Application: For binding plated heat insulation materials installed for internal mouldings (XPS or wood wool plates) into fresh concrete. The necessary material demand on vertical surfaces is min. 8 pieces / m2, for ceilings min. 10 pieces / m2. The mandrel when pushed through the insulation plate (with necessary pre-boring) is bound at the time when the worked-in concrete solidifies. |
