THE SCIENCE BEHIND INSULATING CURTAINS AND BLINDS
When it's cold outside the windows panes in our homes become cool to touch, and the air close to these window panes will be cooled. Cool air is denser (heavier) than warm air, so as this cooled air sinks, it is replaced by warmer air from other parts of the room. This creates a circulating air current which will cool the entire room. Window furnishings are designed to trap the air between the window and the curtain or blind, to prevent this circulating air current from forming.
Insulating curtains have been identified as one of the most effective ways of reducing heat loss through windows. What gives a curtain its insulating properties is its insulating lining, and its well-fitting design.
Lewis’s also partner with Luxaflex to provide a range of attractive insulated blinds. Duette Blinds are very effective at trapping large amounts of air in their cellular structure. They are also available in block-out materials that have a reflective foil layer to reflect radiation. As a result, Luxaflex’s Duette Architella range in a block-out fabric offer 33% more insulation than double glazing.
