Istoric: de la fatade grele la fatade usoare

Inchiderile traditionale erau grele (caramida, piatra) si aveau dublurol: de protectie si portant.

Grosimea peretilor de inchidere era mare (40-100 cm), reprezentando fractiune importanta din suprafata construita.

Etapa urmatoare: inchideri din zidarie de BCA: greutate mai redusa,rosime mai mica 25-30 cm izolare termica mai buna fara rol

portant.

Din anii 50 apar peretii cortina: fatade usoare (40-60 kg/mp),grosime mica (circa 10 cm), fara rol portant.
