What can I use to draw heat/sunlight into the windows of my home?

Is there a product/film for windows on the market to help draw in the suns heat to warm up a limited use room?

    No the film treatments do the opposite. Plain glass windows do that. You must have good windows that protect you from the sun.
  • I would agree with Kelli.

    All film treatments I am aware of keep the sun or heat out. The best you can do is to place windows in south facing walls and avoid any type of over hang. You could also prune trees or any plants that are blocking the windows.

    Hi Rochelle,

    The window treatmemnts block the sun and provide privacy, you might consider replacing your windows with good quality windows. How is the insulation in that room including the ceiling? It might be a good idea to have an energy audit for your home so you can proceed with correcting the problem.

    If the room has a door, opening it more often might help with evening temperature in the room with the rest of the house. Best to you.

    Tilting blinds will enable you to better control sun's angle to admit most available light. Although a pain to clean if not between the glass panes, metallic blinds will hold and reflect more heat.

    Note that mirrors, placed on walls perpendicular to the windows may help to "bounce" more sunlight into the room. Rugs and fabrics may also help with heat retention, as will thermal, ceiling to floor length draperies, which preclude massive heat loss, after dark.
