About H-Flachs

„I take the liberty of doing things away from established structures. Always aware that I have responsibility for my environment and future generations.“

Wolfgang Hagenauer

Flax stands for the philosophy of H-Flachs: generate a sustainable and individual benefit for the customer.

When founding his company in 2010, Wolfgang Hagenauer decided to make flax the basis and name of his company.

Due to its properties, the raw Flax is the material of choice for H-Flachs in the range of door systems for fire and sound insulation.

Flax represents the pioneering spirit of the company. Together with the customer, H-Flachs to finds solutions away from established paths and structures.

In 1998, H-Flachs managing director Wolfgang Hagenauer got to know flax as a raw material in the Netherlands. He was impressed by the advantages of the material: lightness with stability at the same time, high insulating effect and above all the residue-free processing of the plant.

Flax Boards

For centuries, flax short fibers have been produced in the linen industry as waste product in the processing of flax into linen. They are used to make natural boards or stuffing material, for example for door seals. Flax is ideal for both. Flax boards are tensile and stretchy. They absorb moisture without damage and release it again. A big plus of the flax board is that it keeps its shape constantly, so it doesn’t shrink. Flax is characterized by very good heat and sound insulation.

The fire protection class is easily achieved by adding fire-retardant substances. Flax is not only suitable as a door panel, but also as a floor covering or as a board for furniture construction.

Closed cycle in the production of flax

The raw material is ideal for ecological construction and therefore particularly well suited for allergy sufferers. The bitter substances contained in flax keep insects and rodents away. The plant is not susceptible to mold or putrefaction. There is virtually no need for chemical treatment when growing. The closed production cycle and the full use of the plant is the special characteristic of flax. From organic cultivation to complete processing, composting and use as a mulch material, flax is a sustainable raw material.

 „What fascinates me about flax is the closed material cycle, based on a naturally grown, traditional agricultural structure.“
