Attachment	Loose laid (and suitably ballasted). Guidance for specification option: Setting out: Loose lay insulation directly over the capping sheet to brick pattern with staggered joints. Minimize cutting and avoid small pieces at perimeters and penetrations. Dependent upon the total thickness required, it may be necessary to construct the insulation using two layers of board. The manufacturer/supplier can advise on the available combination options. Joints: Butt together. Loading over inverted insulation (minimum): Ballast (landscaping) should be installed onto the Bauder WFRL Membrane (Water Flow Reducing Layer) to a minimum depth required to achieve a permanent minimum 80 kg/m² and load which prevents wind uplift and flotation of the insulation in high winds and/or heavy rainfall. Additional loading at perimeters: On high buildings in more exposed areas, wind uplift may be a problem and in these instances paving slab ballast must be considered. Paving slabs should be a minimum of 50 mm thick. The slabs should be laid on paving slab supports of minimum 175 mm diameter (or equivalent base area). All final details must to be confirmed with Bauder before proceeding.
