Basic science lessons tell us that heat and sound are absorbed when they come in contact with a material obstruction. Window coverings provide exactly this kind of an obstruction and absorb a certain amount of sound and heat. Absorption of sound and heat is known as insulation. While all window blinds provide some amount of insulation, some window blinds are manufactured with an enhanced capacity for insulation. Such window blinds are known as insulated window blinds. Insulated window blinds also prevent heat loss from houses during cold seasons.
While all materials absorb sound and heat to some extent, some materials are better insulators than others. Such materials are used to make insulated window blinds. Certain methods of construction also have an effect on the insulation properties of window blinds. Manufacturers make use of such construction methods and materials to optimize the insulation properties of insulated window blinds.
The insulation effectiveness of window blinds is also affected by their position. One cannot expect any amount of insulation from open window blinds. While closed window blinds offer maximum insulation, the effect comes down with the blinds being left even partially raised.
The earliest insulated window shades were generally the creation of innovative people who had to solve problems of heat loss and excess sunlight streaming through their windows. As the idea caught on, insulated window shades were made commercially. From their earliest form of quilted window coverings, insulated window shades are now seen in their latest form of cellular window shades. Box shells are constructed to trap air; this increases the insulation capacity of these blinds.
Cellular shades are very compact and lightweight. Soft textured, woven and non woven fabrics are sandwiched together to enhance insulation properties of window blinds. Manufacturers offer single, double and triple cell designs in combination with a variety of pleat sizes, fabrics and colors. Options for manual operation and motorized operation are provided for ease of use as per positioning of these insulated window blinds.
Some insulated window blinds are treated for flame resistance and color fastness. These blinds are easy to clean and maintain in a pristine condition that optimizes their insulation properties.
