Insulating & Energy Saving with Curtains and Blinds
A significant percentage of heat loss in winter and gain in summer is transferred through glass of windows and doors. Glass account for a sizable proportion of the total surface area of buildings. Quality curtains and blinds help insulate a room and so reduce energy consumption, saving you money, and reduces your green house gas emissions.
Windows left uncovered allow the transfer of both warm and cool air. Lined drapes place a barrier between the room and the window. Either cool or warm air is trapped between the back of the lined curtain and the glass, while the warm or cool air stays within the room. Pelmets and curtains that return back to the wall on each side of a window help further stop the transfer of air.
The addition of an interlining, will insulate even further. Interlinings are sewn between the drape fabric and the lining forming an additional insulating barrier. Curtains made with bumf interlining also help sound insulation (ideal for home theatres). Blinds made with fabrics developed specifically to reduce both UV heat and glare will insulate a room while still providing good vision to the outside. Blind materials now available with interwoven aluminium reflect direct UV heat and also radiated heat. Until the use of interwoven aluminium fabrics there had been no fabrics that effectively reflected radiated heat. Heat inside a room can be reduced by up to 12’C with the use of these fabrics.
