The insulating capacity which acts as a barrier against cold is one of the most outstanding properties of down and feathers (the capacity to store warmth, heat insulation). This property is grounded on the capability of down and feathers to store millions of insulating air-filled buffers.
You know that air is not a good heat conductor. For instance double glazed windows and cavity bricks benefit from this property.
The air between the two layers of double glazed windows has an outstanding heat insulating effect.
The same physical principle works with a down- and- feather- filled quilt. The down and feathers form countless air-filled pockets which make up a large percentage of the volume of the quilt. These air-filled pockets make up the insulating layer which prevents the heat of the body from disappearing.
It is almost impossible to examine the filling of finished products and check, whether the composition of the filling was reported correctly on the label.
At this point, you should pay attention to the indications reported on the label. The product properties are confirmed there and the quality standards that apply to the product are indicated.
The TRAUMPASS and Daunasan® / Downafresh® refer to the filling. It is stated by NOMITE that the quilt is suitable for house-dust-mite-allergy-sufferers, and the KIS® Komfort Information System is a valuable assistance for you to choose the optimum quilt.
