Thirachai Thonchai, 47, his wife, and their three children escaped uninjured after the fire broke out in the first floor of their house in Tambon Thepa of Ban Chang district about half an hour past midnight.
Firefighters took about 30 minutes to control the blaze.
Thirachai told police that he was woken up by the smell of smoke and the heat. When he opened the bedroom, he saw thick smoke coming up from the first floor so he woke up his wife and children.
He managed to remove the iron grille of the window and shouted out to his neighbours to help receive his children from him before he and his wife climbed down.
