  • If you are looking for special acoustic protection glass, you can generally add around €100 to the price of your window. Other types of glass such as mirrored, self-cleaning and other special coated glass will come at different costs. This depends on your window provider and their supplier. For such special requirements, speaking to a professional is the best course of action.
  • We estimate that you will have to pay €40 more for a window with toughened glass. If you require laminated glass, the final price of your window will increase by €55 relative to the price of a window with standard A-rated glass.
