Dear 100 Hour Board,
Cold air comes in through my closed window. I put some clothes along the bottom of the window to try and help with it and I keep the blinds and curtains closed. But it's still coming in, especially from the sides. As a university student renting an apartment, what can I do that will help keep me warm without getting in trouble with my landlord?
already too cold
Dear Cold Outside,
Well, I can't tell you what you can do without getting in trouble with your land lord, but I can tell you about what you can do keep yourself warm.
So there are two ways that the heat gets out: warm air escaping, and heat transferring through the window. If air is leaking out, then sealing the windows better will keep you warm. If heat is transferring through the glass then the way to prevent heat escaping is by insulating the windows. My first thought was to duct tape a blanket to the window, but if you want to go with something a little less make shift then there are some good suggestions on this site.
In Canada, plenty of people use plastic film insulation on windows. Click here to get any idea of what you need and how to do it.
It's a crude solution, but cardboard is a reasonably good insulator and jamming a flattened box into the window frame is a temporary solution that blocks quite a bit of heat loss, much of which is through the window itself. Plastic kitchen bags can be used along the sides to block air flow. It's dark, but temporary, and it's helped me before. If you're not a fan, just take it out and go with some of the more elaborate solutions discussed above.
