How do shades insulate your windows?

Did you know that large uncovered windows are the biggest source of heat loss from a well insulated home?

Innovative Openings has specialized in Insulated Shutters and Shades since 1980.  The key to understanding window heat loss starts with an analysis of your home and windows.


Heat escapes through windows by 3 different methods:

Conductive Heat Loss at Window Openings

Window Quilt Insulated Shade

If the windows tightly sealed (weatherstripping), conductive heat loss is typically the largest source of heat loss.  R-value becomes the most important measure of heat loss through these windows.  An insulated window shade that adds an R-value of 2 will cut the heat-loss through a double glazed window (approximately R-value = 2) by 50%.  An R-6 shade would reduce heat loss through the same window by 75%.

Some of our best solutions include Duette Architella Honeycomb Shades and Window Quilt Insulated Shades.

Air Infiltration at Window Openings

With windows that have a loose fitting window sash, air infiltration can be a larger source of heat loss than conductive heat loss.  The first step is to address the window seal with caulk, weatherstripping, storm windows, or replacement windows.  Window shades with tight sealing track systems will further reduce any air infiltration.  This is often a good solution for aluminum sliding windows.

Some of our best soutions include ComforTrack Insulated Shades and Window Quilt Insulated Shades.

Radiant Heat Loss at Window Openings

Radiant heat loss is shown by the cold drafty feeling that you get by sitting next to a large uncovered window on a cold winter night.  Closing any type of window covering over this window will make the room feel warmer, but certain window treatment choices will provide greater comfort and efficiency.  Ideally, a shade with reflective properties will reflect the cold out and keep the heat from radiating out and provide an effective radiant heat barrier.

Some of our best soutions include SilverScreen Shades Duette Architella Honeycomb Shades and Window Quilt Insulated Shades.
