It was really hot summer, and finally the air got livable and nice one to work on project lately here So I decided to make another window DIY before it gets cold.
The DIYing the second layer window, inner ones, was my project last year on north side of the dining room. That old window had a normal but thinner glass which was letting both heat and coldness into my house.
Asking and hiring constructors are wise choice, I know, but I have no other choice with very limited budget. Here is what I have done.
