Church St. Trinitatis
St. Trinitatis Provost Church in Leipzig is the largest church building in East Germany. Sustainability and durability of the construction were two main goals for the structure. FOAMGLAS® cellular glass was the perfect insulation solution for the façade and roof insulation as it does not absorb water and is vapour diffusion tight.
The principal’s high demands on the sustainability and, in particular, the durability of the constructions were satisfied thanks to the outstanding properties of the FOAMGLAS® cellular glass insulation. “The holistic optimisation and execution of the reconstruction of the St. Trinitatis Provost Church in Leipzig as a model ecological project” was funded by the German Federal Environmental Foundation (DBU) with a total of EUR 450,000.
“A large new church with a new community centre is being built here, and the principal wishes for the construction to be as sustainable as possible. Against the background of the fundamental commitment of the church to the integrity of creation, this can truly be regarded as a lighthouse project and a concrete sign of responsible and ecological building,” said DR.-Ing. E. h. Fritz Brickwedde, General Secretary of the Foundation. The funding notices provided for the priory church to spend a total of a further roughly EUR 790,000 in order to enable this sustainability orientation.
A core insulation of FOAMGLAS® W+F on a supporting structure of steel-reinforced concrete and a cladding shell of Rochlitz Porphyry natural stone was used for the façade. As FOAMGLAS® insulation does not absorb water and is vapour diffusion-tight, the normal ventilation level was not required, with the corresponding benefit for the use of the construction window, i.e. the maximum area of land that can be built on.
