gräfix 76 grey
Grey adhesive and coating mortar
CS IV · grey, for gräfixtherm external thermal insulation systems
This emulsion-modified thin-bed mortar, containing additives to facilitate application, is primarily used for bonding and coating gräfix polystyrene rigid foam and other rigid foam, mineral fibre and soft wood fibre boards, and similar materials across the entire spectrum of thermal insulation applications. As a coating mortar, its high elasticity makes it ideally suited for embedding reinforcement mesh. Once dry, the applied render layer can be easily covered with a thin-layer finishing render. We generally recommend priming the surface with RABOLIN 160 render primer before applying the finishing render.

External thermal insulation composite systems
Thermal insulation for new builds and refurbishments
Thermal insulation that is professionally planned and installed can reduce heat loss through the building envelope, thereby influencing a building’s heating energy requirements. The extent of the potential savings depends, amongst other things, on the building, the existing wall construction, the insulation thickness and the building’s use.
gräfix-therm external thermal insulation composite systems offer tailored system solutions for the insulation of external walls. Funding opportunities may also be available for certain energy-efficiency refurbishment measures.
In addition to the technical properties, the façade design offers a wide range of possibilities: with different colours, textures and finishing plasters, the various insulation boards can be individually finished and adapted to the design of the respective building.
In combination with suitable products from the gräfix lime range, mineral-based and vapour-permeable surfaces can be created for interior applications.
