I am thinking of covering the window panes with 5 fold newspapers.

What other inexpensive items/materials can be used to cover the window panes for keeping the house cool from inside?

  • Why not some thick shades, or curtains? – Tester101 Jun 24 '11 at 11:55
  • @Tester101, in India, DIY takes on a new meaning. I'm amazed by the creativity there. – BMitch Jun 24 '11 at 11:59

I see you're writing from India, so the standard US answer of installing light blocking cellular blinds may not apply to you.

Consider using a thin material that reflects light instead of absorbing much of it, such as aluminum foil. If you want it to look nice, you can stack the foil between a light piece of paper for the outside (so the neighbors aren't blinded by the reflection) and cardboard (for rigidity).

    The aluminum foil works, I've done it myself, but I like the idea of backing it with cardboard. Maybe making a sandwich out of a few layers of cardboard and foil and then taping it to each individual frame would work. Do you run AC? – electricsauce Jun 24 '11 at 13:42

    Newspaper will insulate, but it still absorbs a lot of the light, rather than reflecting it away. That said, it's good enough for Air India pilots, so it can't be that bad of an idea :) nytimes.com/2011/05/26/business/global/26airindia.html – BMitch Jun 24 '11 at 15:46

    You want the light for heat in the winter, so I'd take the foil down. Then, block any drafts from the windows. Here, that involves weather stripping and maybe a plastic wrap. If you're improvising, a rolled up towel along the bottom of the window sill is a start. – BMitch Jul 2 '11 at 11:04

    Your English is better than my Hindi. Drafts are gaps that allow cold air to pass. Weather stripping that we get in the US is usually a foam or rubber material that can be compressed in the gap to form an air-tight seal. – BMitch Jul 2 '11 at 15:45

    I did use Aluminium foil in the past summers, and they "did work" superbly. The temperature downfall was remarkably noticeable. Thanks to you. – Aquarius_Girl Dec 6 '12 at 4:13

Foam Panels

I'm not sure that this would be available to you locally, but this is what I use on my bedroom. Cuts easy and has a reflective side and is very cheap. Works well enough to keep the Florida heat out of 50 year old leaky windows.

  • That looks cool, but I am not sure if it'll be available here! – Aquarius_Girl Jun 24 '11 at 13:18
