The protection measures for church windows are of great importance, especially for windows that are made of leaded glass and are often of historical and cultural value. Installing protection devices such as Hammerglass Single helps to protect these valuable windows from vandalism and damage without compromising their appearance and aesthetics. This report describes the installation of Hammerglass Single to secure large leaded church windows.

In 2016, Hammerglass Single was installed to protect large leaded church windows of approximately 6 metres in length. The panes were connected using a tongue and groove system and mounted with transparent Hammerglass angles for security. Hammerglass was chosen as the material for the guard due to its light weight and high safety rating. Hammerglass weighs only half of normal glass, which allows it to be fitted into existing structures. In addition, it offers greater security than conventional glass.

The system installed was Hammerglass Single 12 mm. The installation was carried out by Hammerglas AB, a company specialising in glass protection and producing products such as Hammerglass Single.
