coating / SIVA

Plastering was made out of cement (350kg/m^3) with %50 - %50 sand and perlit mixture. Perlit helps for better heat isolation but coating the walls with rock wool plates from outside would be a better solution.




Sıvada 350 dozlu çimento harcı ve %50-50 kum-perlit karışımı kullanıldı. Oysa tuğla yüzeyleri dışardan taşyünü levhalarla kaplanarak daha iyi bir ısı izolasyonu elde edilebilirdi.
