MODERNISATION WITH XERAL INSULATING PLASTERS
XERAL’s innovative mineral insulating plasters can be used indoors and outdoors and really display their strengths in the energy-efficient renovation of listed buildings through their inconspicuousness compared to other façade insulation.
Beyond the effectiveness of the thermal insulation, this insulating plaster stands for a balanced indoor climate, a healthy living environment due to fungus protection, fire safety and sustainability thanks to the use of recyclable non-fossil raw materials.
Prestigious buildings from the Wilhelminian era are very attractive – especially after successful modernisation – due to their mixture of today’s living comfort and the charm of stucco and high ceilings.
Core refurbishment of such properties is often confronted with the demanding requirements of protecting historic buildings. Not infrequently, the elaborate street façades of such buildings are not allowed to completely disappear behind a thermal insulation system.

INCONSPICUOUS INTERIOR INSULATION
SUCCESSFUL DEPLOYMENT OF XERAL PRODUCTS
This property is a city mansion in one of the most attractive residential areas in Heidelberg. The village character around the marketplace, the bourgeois city houses with Wilhelminian frontages and the lively, mixed-use green quarters make this area so popular. The quarter gains additional charm through its proximity to the riverside Neckarweise green area and the Philosopher’s Garden.
This prestigious building was built around 1900 and used as a residential building. Today, following successful modernisation, there is a paediatrician’s surgery in the basement and attractive period apartments on the remaining floors. The property is listed.
Before renovation, it stood empty for a number of years. Core refurbishment was unavoidable in order to breathe life back into the building. Heidelberg’s Building Legislation and Monument Protection Authority was involved right from the start. After gutting the building, extensive renovation and modernisation was carried out. The protected façade was also cleaned, coated with renovation plaster and repainted. Red sandstone typical of the period was used for the window surrounds and the corners of the building.
The main building measures took place in 2018. Renovation was finally completed in mid-2019 with the completion of the apartment in the basement.
