Bottom-Up Insulating Shades for Light and Insulation -- Our R8.3 Window

On some of our windows that we have no need to look out of, but still want some light, we use a 3/4 insulating shutter on the bottom of the window.   I like the 3/4 shutter idea because it does a very good job of insulating most of the window, while still letting a lot of light into the room.

The 3/4 shutter got us to wondering if a top-down/bottom-up insulating shade could be used in the same way -- we decided to try this on one of our windows.

Our first try at an insulating top-down/bottom-up shade.
This window is a bit odd with the triangular top, and I had to add a support board to hold the top bar of the shade in place.

This arrangement allows us to have the shade fully up at night for privacy and maximum insulation, or during the day to have the shade part way up to allow more light and views with some insulation.  Normally we would have it up more than the picture shows during the day to get somewhat more insulated area.

The new shade is from Symphony Shades and in addition to being a good double cellular insulating shade, it has side tracks that reduce air flow around the sides of the shade.

The side tracks prevent airflow around the edges of the shade.

It turns out that this window already has a double Mylar inside storm window on it (bet you could not even see it :), so the total insulating value is:  low-e window (R3) + double Mylar storm (R2) + insulating shade with side tracks (R3.3) is a sort of amazing R8.3!



  1. Looks like a nice neat super shade. Good solution.
    Now you can save heat and still have a great view.

    1. Hi John,
      We find that we use the top down quite a bit -- it lets you look at the views, and still insulates part of the window.
      Very satisfied with them.

  4. I guess there is no harm in trying. Testing what could be the perfect type of window for your home is efficient for future events that may occur.

    1. It is really a great solution described in your post, most of the time we lack ideas, but the current scenario is really appreciable and we can get the hold on energy efficient products.

  5. It is a very innovative concept in which a window can work as a door also with the help of shades.
    It prevents the extra sunlight causing glaring problem.There is a variety of shades available in the market so a buyer is free to pick and choose the color and design of their own.

  6. Top down, bottom up is popular because it can meet privacy needs while still allowing access to natural light. This fully functional window treatment gives a clean and contemporary look.
