A border for anyone to use. And an image showing solid internal window shutters (maybe a corner of a room in Europe) and text about the usage of internal window shutters. They can help to make a room warm at night in winter and cool in the summer. They could be 'bifold" so they sort of fold agains each other on the sids of the window frame, or like this that go out against the wall and are pretty much half of a windows width. Louvered shutters you would need to point inward and upward to keep the heat from going out through them to the window and hence outside and be lost in winter. But louvered shutters can control air flow when the outside window is open. Sometimes it is a privacy issue. If you have louvers horizontal you can see out but people from the ground below have a hard time seeing into your window.
I like the solid ones so that if you want to you can leave them open a small space between them having a vertical shaft of light and less ability for folks to see in. But most of all I like the way the solid shutters can turn a window into a wall at night to keep the winter heat in. Hardly ever do I need to look out the window if it is time for sleeping when I do want the warmth to stay in and not have to run a furnace a lot at night.
Can not remember where I saw the image of I think his first name is David, but when I saw it I thought of those shutters and wanted to search and tell people about them. If you had multiple shutters, like top and bottom the top could be open to allow light and such in and the bottom ones closed for privacy.
I have talked enough, enjoy the day and look into the many benefits of internal shutters for your home.
