High quality blind fabric from Living Shade to reduce heating costs
With the heaters on we are often asked "how effective is aluminium
in reducing heating costs?" We know about 40% of energy is lost through average
windows in a house with single glazed windows.
The U Value
This is a measure of the insulation capacity and here we are comparing our three
main products, Ombra, Mood and Optic. The more aluminium used, the greater the
insulation capacity is. Also, it is important to have 'good quality' aluminium and
then the tighter the fabric, the more effective it is.
Insulation is a factor that sometimes is neglected when choosing window covering
products. However, the savings on heating are sometimes substantial in cold climates.
U Value describes the heat flow through the glazing per unit of time and area when
the difference in temperature between the two sides of the construction is one
degree, given in W/m²K.
For example, if the U Value is 4.0 without a blind - with our Ombra as a blind, it
becomes 2.6. A 35% reduction.
Tests done in Toluca Mexico shows the reductions under single glass. With a normal
blind fabric, the savings are about 25%, but with Svensson aluminium, you can see
they can be as much as 50%.
Summary
A better result is obtained by using more aluminium and higher quality fabric. If
