Best way to block out windows?

[Doc_Possum]

I want the windows to be sealed off completely from light and I don't want a bunch of bugs getting in there and making a mess. Anyone have any good idea to block out the windows?

You want to block light or close off completely? Garage window? Brick?block?stick frame?

Rigid insulation wrapped in upholstery fabric with white vinyl against window. Velcro to hold top in place. If removing and replacing, split vertically and velcro on walls like interior shutters.

Or, polygal on exterior of window. Wrap it in adhesive sign vinyl or Sunbrella fabric. Lexan will protect from flying baseball's and provide a tiny R value.

The next owner may work days and love windows.

Or, shelf paper and aluminum foil. The HOA will have rules against this and police will suspect criminal activity.

The way this guy did it seems like a great solution to your problem.

Screw a piece of plywood over it.

Black paint on the glass, works great.

Black paint on the glass, works great.

I did a basement window with black paint on the inside first coat so its dark from the outside. white paint on the inside so it doesn't look dark
from outside can't tell its been painted out, inside, well its in pantry so it is what it is.

Black paint on the glass, works great.

I did this, and that pane cracked (likely from expansion of the glass from the additional heat). I also had 3 other panes in the house crack after tinting from the same reason, so it could have a lot to do with how they were all manufactured, but it's something to be aware of...

This is the pertinent information that we need to give you the proper advice.

I bought and continue to use Venetian Blinds. This idea is a terrible idea for "darkening". I have bug and spider cities behind and around the blinds. I would never use Venetian Blinds for a black-out again. If I ever have a chance to build another shop/garage, the building will not have windows.

Being a midnight shifter for many years I used cardboard precision cut to the opening which was fast and worked well enough. I had to hoard up some bigger sheets.

Paint will work -- black to eliminate all light and thin coat of white if you want to block the view. Many light fixtures w/ glass shades are painted.

are you looking for privacy, light blocking or security? Is ventilation a concern? Tell us what you are looking for and you will get better advise. One option not mentioned yet is glass blocks, can be distorted enough for privacy, good security and still allows light. There
are even some options which would allow some ventilation.

Heavy cloth and velcro worked pretty well when I worked nights. It was also easy to open the curtain to clean the windows or let light in the room.

They sell blackout curtains if you don't want to make them yourself.

I will try out this way

I have made vinyl coverings for people on my 54 inch wide vinyl cutter. They tell me the side and its cut to fit.

We don't know why or what you are trying to do where?

My MIL sells all kinds of window blinds, we have sun blocking cellular shades in our bedroom, they are pretty great.

Depends on your window. If it's double pane, don't do anything to the inside of the glass. It will trap heat inside and cause the gas inside to expand and crack.
