How is the warmth index graded?

Working with the internationally recognised "Neutechnikum Buchs" we have developed a sensitive, computerised measuring system for the classification of quilt warmth.

This classification grades on two specific parameters:

  • the warmth retention capacity of the quilt
  • the moisture absorption qualities of the quilt

Both parameters together allow the quilts to be classified into four categories. The warmth index will be provided with every quilt.

Warmth index

Quilt with very little warmth retention. Recommended as a summer quilt or as a quilt for heated water-beds or for sleepers with very little warmth requirement. Also for sleepers in heated bedrooms.

Warmth index

Quilt with little warmth retention. It is recommended for warmer regions and between seasons. A quilt for water-beds and for sleepers with little warmth requirement or in heated bedrooms.

Warmth index

Quilt with average warmth retention. It is recommended as a quilt for all year round and for sleepers with an average warmth requirement. Also for sleepers in gently heated bedrooms.

Warmth index

Quilt with high warmth retention. It is recommended for use in every season and especially for the cold seasons and for people with high warmth requirements sleeping in unheated bedrooms.

Index by double quilts with various quilts halves

The 4 seasons or double-quilt consists of two single quilts, each with different warmth retention capacities, which can be buttoned together. They are designed to be used separately or together to meet the sleeper's personal warmth requirements for all four seasons.
