all my windows ket cold air in, so even with the heating on the place is so draughty. its a council place with double glazing, but its so cold. there is a weird air vent thing as well on the ceiling in the hallway, if you switch it on, it blows cold air in during the winter and boiling hot air in the summer. but even with it switched off it does let draughts in. i need to call the council in, but i have a feeling it wont be a prioity, so what can i do about the windows in the meantime?
