You could just chill out. Putting up bars or plastic on that door is truly ghetto. Doors like this are not inherently unsafe at all. Your door is appropriate for your neighborhood. Your door ...

Will window shrink-wrap make a noticeable difference in heating bill in house with single-paned windows?

What can I do to cool down the room?

First of all cardboard is not a good reflective insulator. Second, hanging cardboard on the inside will not help much since the heat has already entered the room through the glass. Get some aluminum ...

Will window shrink-wrap make a noticeable difference in heating bill in house with single-paned windows?

Air has pretty good insulation value if you can stop it from convecting. If it convects, it transfers heat fairly efficiently. Fiberglass and rock-wool matt rely on this - the point of the strands is ...

Why tape black garbage bags to outside windows, not between inside windows and blinds?

Insulating an open window with air conditioning pipe through it

How do I keep a broken window closed while waiting for a replacement to arrive?

If you really don’t want to force it, just put an oversized piece of plywood (1/2” or so) over the entire opening. *Don’t do this if the window is a legally required egress route. If you’re concerned ...

How can I reduce noise coming in a window for under $100?

Is it possible to rotate a window 90 degrees if it has the same length and width?

What is this black sooty material on the inside of my roller shutter?

Clean it up with bleach and a sponge (chlorine is the main ingredient of mold-cleaners). If your home is humid (RH >55%) consider installing a dehumidfier so with less moisture you get less mold.
