Pleated Blind in a Large Window

Best Window Coverings for Insulation

Roller Blinds 

When pulled down, Roller Blinds create a barrier between the room and the glass of the window. This creates an air gap, which in turn improves thermal insulation. However some fabrics create a better barrier than others. 

Thicker fabrics such as ones with a Blackout or dim-out backings work very well, especially with Solar Gain. 

Roman Blinds

Roman Blinds with a lining also make excellent Thermal Blinds. Again the addition of the lining adds another layer which subsequently improves the thermal properties. With some of our Roman Blinds it is possible to add a thermal interlining for added heat loss protection. 

Shutters 

With a full frame and thick louvres, Shutters make excellent insulators. Especially the wood shutters. Wood is a fantastic natural insulator for both heat and noise, however, even Polyvinyl or MDF Shutters will work well too.

Pleated Blinds 

Cellular Pleated Blinds are also excellent for keeping the heat in! The honeycomb finish helps to trap air, helping to prevent the heat loss.

The great thing with Pleated Blinds is they can be mounted to Bi-folding doors where there is a wide expanse of glass. Thus reducing the heat loss or Solar Gain through the glass.

Best Practice

During the Winter

  • Close the blinds as soon as the Sun goes down to prevent heat from escaping.
  • Open your blinds fully on sunny days to maximise Solar gain from the sun to warm the room.

During the Summer 

  • Shade rooms on South elevations to reduce heat from Solar Gain
  • Open Blinds on West and North elevations especially during the night to assist with night-time cooling
  • Close Blinds on East and South-East elevations over night to reduce heat gain caused by early moring sun
