What is the minimum U value for windows?
1.6 W/m2KTo comply with building regulations, windows (like every other element of your property) must meet a certain minimum U-value. In the case of a window, it’s 1.6 W/m2K. Double-glazed windows, filled with argon, are typically 1.4 W/m2K, while thicker triple-glazed windows can go as low as 0.7 W/m2K.

What is the minimum area of a room in a house for better ventilation?

What is the U value of single pane glass?
