Glazing works on historic buildings? Our window putties, EGOPUTTIES, have proven themselves for decades and are perfect for single glazing for windows to be restored.
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. V., Rosenheim.
Window putties from EGO are perfect for:
- Single glazing in timber and metal windows as well as combinations thereof
- Greenhouse glazing, industrial glazing, lead glazing, and much more

How long does linseed oil putty take to dry?
That depends on multiple factors such as chamfer geometry, temperature, oxygen, light and humidity. It can take days or even weeks until initial skin formation. Important: The putty must be painted over. After sufficient skin formation at the earliest, after 8 weeks at the latest.
What applications is linseed oil putty suitable for?
Linseed oil putty is particularly suitable for single glazing in timber and metal windows, predominantly in historic buildings, as well as for greenhouse glazing, sealing of glass roofs and industrial glazing. Linseed oil putty is also the right choice for artistic glazing in lead, brass or light metal. Glazing systems in accordance with RoTa Va1.
Can linseed oil putty be painted over?
