The basic elements are the Silvacor W07 and W08 clay blocks with a coefficient of thermal conductivity λR [W/(mK)] of 0.07 or 0.08, available in the wall thicknesses 30, 36.5, 42.5 and 49 cm.
In addition to these, special, newly developed reveal and levelling blocks are now available. With the levelling block, Hörl & Hartmann has brought out another product for optimizing efficiency. With standardized intermediate sizes in heights between 12.4 and 22.5 cm instead of the normal size of 24.9 cm, room heights and window parapets can be installed without the need for sawing on site.
Minimizing thermal bridges
Particular attention is needed to avoid thermal bridges at typical joints in the building envelope, which can have different properties if the masonry is not homogeneous. A ceiling edge block supports energy-optimized installation of floor slabs. It consists of an outer clay shell and two thermal insulation layers of Neopor and is available in the standard wall thicknesses between 30 and 49 cm as well as for slab thicknesses between 18 and 24 cm. For installation at floor slab edges without supports, like, for example, lintel-free window openings, the company manufactures a variant with back anchoring.
