How curtains and blinds can save you money and retain heat!

Stepping into the New Year is the perfect time to reassess ways of saving money and insulating your home.  The thermal properties of curtains and blinds can have substantial effect on your overall energy bills.  Curtains can reduce heat loss through single glazed windows by up to 60%, and up to 40% to 50% through double glazing.


But what are thermal curtains or blinds?

The aim of a good pair of curtains or blind is to create a seal between the curtain/blind and the window, preventing cold air from getting into the room and keeping warm air in. Often, a curtain or Roman blind is made up from either two or three layers:


Two Layer Curtains

A two-layer curtain or blind consists of an outer layer of fabric (this is the side which is coloured or patterned) and a lining layer. A plain lining offers segments of thermal insulation but primarily, helps the curtains to hang nicely and protects the outer fabric from sunlight damage. A blackout lining is a coated cotton lining; providing better insulation.


Three Layer Curtains

Three-layer curtains are generally more expensive due to the amount of fabric used but they are the most cost effective in conserving energy. Intertwined in a two-layer curtain; their secret component is an extra layer sandwiched between the outer fabric and the back lining. This interlining layer provides more heat insulation and added weight to help curtains hang and look fuller in appearance.


How to achieve good insulation from your curtains and blinds


To achieve optimal energy conservation and still retain a great interior look, ensure your curtains are:

  • Floor-length and touch the floor (heat can still escape if the curtains touch a window sill); and have an almost touching pelmet to retain the heat.
  • Wider than the window frame but are as close to the wall/frame as possible
  • Double layered with a thick lining.


Blinds can also achieve great thermal retention if positioned correctly.  Reduce your energy bills by ensuring your blind:

  • Fits tightly in the window frame, trapping the air between them and the window. Smaller the gap, better the thermal properties.
  • The thicker the blind, the better it will hang and retain heat. Use blinds which have a thick lining; helping achieve optimal usage from our window dressing accessory.
