Overview EGO putty

Possibilities of glazing systems.

Window putties from EGO are produced using mountain chalk from Kaltenbrunn which we mine ourselves. Window putty has the advantage of adequately sealing single glazing in listed buildings without damaging the property to be renovated. It also guarantees a seal in accordance with Groups 1-5 of DIN 18545: Sealing of glazing with sealants and the “Chart for determining the load-bearing groups for window glazing (RoTa)”, developed by the Institut für Fenstertechnik e.
