One of the easiest ways save energy in the home is by the use of good quality soft furnishings at the windows or sliding doors.
Curtains with Pelmets are by far the best option as they trap the heat/cold behind the Curtain better than Blinds.
One of the best ways to ensure you have control over your environment is to Motorise the curtain tracks. This way they can be programmed to open and close at set times or even controlled with a phone when away from the home.
These days, Battery motors are becoming increasingly popular as there is no need for an Electrician and can be installed as simply as a normal Curtain track.
With increasing demand in these products the prices have become much more affordable with a wide variety of options to chose from.
