Type 3: Stone walls with
wooden flat roof
Location: Mountainous and
cold regions, provinces: Fars,
Azerbaijan, and Khorasan.

mud, gypsum or sometimes no
mortar is used; stone and mud
mortar are not consistent
materials.
Walls are about 40–60cm
thick, more than 2m high and
weigh about
2
1000–1500kg/m .
Type 4: Wooden walls (Zegali/

heat insulator; the structure of
the roof is a truss built from
wood and sometimes steel that
results in a light roof.
Walls are about 25–30cm
thick and weigh about
2
250kg/m .
Type 5: Cement block walls
with inclined roof
Location: Caspian coast in
north of Iran, provinces: Gilan,
