MultiWeave textile-based ventilation duct - textile ventilation duct

This is a representative EPD representing the MultiWeave product group. The textile ducts made by KE Fibertec A/S are either round, semi-round or quarter-round ducts made of a light weight textile material. They are designed for delivery and distribution of cooled or heated air. The textile is suitable for ventilation purposes in schools, offices, shops, showrooms production facilities and food industry, and other types of rooms. The textile ducts primarily consist of two parts. One being the textile tube and the other the mounting equipment consisting of an aluminium rail. The textile used is manufactured at KE Fibertec's own weaving mill and is designed for air distribution. The mounting equipment is made of aluminium. Textile ducts can be equipped with nozzles to enhance good ventilation in large rooms.

The textile-based ventilation ducts of KE Fibertec AS MultiWeave line consist of two main components. Being polyester and aluminium. Other small components are zippers, nozzles made of POM, steel bottom rings and other small metal components e.g srews. KE Fibertec receives polyester fibers. The fibers undergoes the following manufacturing steps: Warping Weaving Laser cutting Sewing The aluminium profiles for the mounting rails are purchased externally and consisting of 73% recycled aluminium. Technical data: The main components - polyester and aluminium - of the ventilation duct covered by this EPD are tested in accordance with the following standards. Polyester: ISO 9001 EN 779 ISO 14644-1 ISO 13937-2 DS 428 EN 13501-1Aluminium rail: BS EN 573-3:2019+A1 EN 515 DIN EN 10204 2.2 Declared unit: The declared unit is 1 kg of MultiWeave ventilation duct including mounting equipment. This study describes the environmental impacts of a representative textile-based ventilation duct of the MultiWeave line manufactured at KE Fibertec. The input material represents a weighted average for all the products under the given product group. The data is based on the production in 2021 and the total production volume of the same period. The processing at the production site is almost identical for the different products. The only difference is the amount of clipping and the addition of nozzles for one type of ventilation duct. An average amount of clippings is applied in this study and an amount of nozzle is added in the modelling. This EPD represents the MultiWeave product group. The differences within the MultiWeave ventilation ducts are the dimensions and permeability of the fabric. However, the production processes of the products within the MultiWeave line are the same. Therefore, a representative EPD is made to cover this product group. The representative product is compiled by using 5 solutions varying in size and calculating a weighted average of each component of the ventilation duct.

KE Fibertecs MultiWeave textile-based ventilations ducts are custom-made to provide the optimal service in the specific room and under the specific conditions they are placed in. The ventilation ducts are made for blowing in and distributing air.
