About Monument Glass

Monument glass, also known as historic glass, is used in the restoration or renovation of historic buildings and monuments. Characteristic of monument glass is the wavy distortion, which originated from the drawn glass technique dating from the 19th and 20th centuries.

By using this monumental glass, the authentic appearance can be preserved and significant savings can be achieved on energy and maintenance costs.

U-value of monumental glass

The U-value of regular double monumental glass depends on the composition and construction of the total package, but varies between 1.5 and 5.6. However, by processing BENGglas

 

Why choose monumental glass?

Sustainability and energy efficiency are essential in today's world, but heritage conservation is equally important. That is why monument conservation may decide to protect certain monuments by imposing rules and guidelines that should protect the authentic appearance of a building or home. This often means that window frames should not be replaced. BENGglas offers a great solution here, as the glass is only 8.3 mm thick.

Nevertheless, specific requirements may be imposed on the finish of the glass, which must correspond to the original glass which shows slight distortions. Monumental Glass is then the ideal solution. However, the insulating capacity of monumental glass is limited (U: 1.5 – 5.6). To improve this, BENGglas offers the option of combining vacuum glass with a monumental counter pane. This way you benefit from the highest possible insulation value, while still complying with the regulations of historic preservation.

*Note: the rules and guidelines of monument care may differ per municipality and monument. Therefore, always consult the local historic preservation office for more detailed information.

Costs of monumental glass

 

Combining BENGglas with monumental glass entails additional costs, but the monument care industry is increasingly accepting BENGglas MAX and BENGglas Extra Clear, where the glass with counterpane does not fit in the frame. It is therefore advisable to always contact the monument care department first to request the exact requirements.
