Sustainable, functional, and organic.
Träullit is a building material that contributes to a healthy and restful atmosphere. It is eco-friendly and renewable, consisting of wood wool from Swedish spruce, water, and cement — nothing else.

Local forest produce

Forest produce that is grown and harvested locally
We cooperate closely with our timber suppliers and always strive to utilize locally grown and harvested forest produce in our production. That means fewer and shorter transports, less use of fossil fuels, and reduced greenhouse gas emissions.

Highest classification from Byggvarubedömningen
Byggvarubedömningen is a Swedish non-profit organization that evaluates building products from a perspective of biochemical contents and environmental impacts throughout their expected life span. Byggvarudömningen aims to enhance and promote the product development of sustainable and healthy constructions with eco-friendly materials and responsible supply chains.

Träullit Acoustic has been awarded Miljöbyggnad Guld, Byggvarubedömningen’s highest possible classification.


Top scores, class A, from SundaHus
SundaHus Material Data is a market-leading tool for effective and result-oriented work with environmentally conscious material choices. Their assessment criteria are based on regulations from the Swedish Chemical Agency’s KIFS 2005:7, Regulation (EU) 1272/2008, CLP, and PRIO, a tool developed by the Swedish Chemicals Agency to help detect and substitute hazardous substances in products and articles.

Träullit Acoustic has, in both painted and natural variants, received the best possible classification, class A, from Sunda Hus. This verifies that Träullit Acoustic does not contribute to negative health effects according to the Swedish Chemical Agency’s PRIO guidelines (e.g. carcinogenic substances, reproductive toxicity, endocrine disruption, allergens) and that it does not harmfully impact the indoor environment by emitting volatile organic compounds. Furthermore, SundaHus establishes that Träullit Acoustic has prominent technical longevity, transparency of material components and that it composes minimal strain on natural resources and landfills.


Declared and registered with EPD Norway
EPD, Environmental Product Declaration, is a standardized, third-party verified declaration that quantifies environmental information on the life cycle of a product to enable comparisons between products fulfilling equivalent functions. The International EPD System provides relevant, quality-ensured, and comparable information that is used in most markets globally to measure products’ real environmental performance.

Träullit is environmentally declared with EPD in White Cement and Cement Grey.


ECOproduct tested — with great results
ECOproduct is a product evaluation certificate for selecting environmentally friendly materials and products in construction projects. It is a collaboration between Green Building Alliance, SINTEF, and the Norwegian Building Centre and is used by architects, contractors, and developers to make the most environmentally superior material selections that are available on the market. ECOproduct is also used as demands on environmental material quality for BREEAM-NOR certification. ECOproduct is the only method that assesses materials’ actual environmental impact based on a third-party verified Environmental Product Declaration (EPD), with recognized international standards and references as a basis for the assessment.

Träullit Acoustic achieved excellent results with regards to the product’s emission values, material contents, resource efficiency, and global warming potential (GWP). Click below for the complete evaluations and results from the ECOproduct testing:

M1 Emission Classification

Träullit Acoustic holds M1 emission classification
M1 classification is a voluntary labeling system open to all manufacturers, importers, and exporters of building products. It sets limit values for the emission of VOC, formaldehyde, ammonia, as well as odors associated with the material, and aims to enhance the development and use of low-emission building materials.

Building materials are classified into three categories, with M1 being the highest ranked. M1 classification means the product has been tested in an independent and impartial laboratory and that it has met the specified criteria four weeks after manufacture.

Material contents

Träullit is completely free from toxicants and synthetic substances.
Our products consist of wood wool from Swedish spruce, water, and cement — nothing else. The result is a sustainable, functional, and organic building material with many different functional characteristics such as heat accumulation, moisture regulation, sound absorption, fire protection, and resistance to mold and rot.

Wood wool — from a sustainable and local forestry

All forest produce utilized in Träullits production originates from locally grown and sustainable forestry. That means fewer and shorter transports, less use of fossil fuels, and reduced greenhouse gas emissions.

Water — clean and fresh, from local groundwater wells

The water used in Träullits production is clean and fresh and is taken from local groundwater wells.

Cement — for strength, fire protection, and persistence

The grey cement utilized in Träullits products consists of limestone and marlstone that is both quarried and manufactured in Skövde, Sweden. Our white cement is manufactured in Aalborg, Denmark.

Träullit is 100% powered by locally produced sustainable energy

Environmentally friendly hydroelectricity locally produced in Ydre
We are proud to take yet another large leap forward in our environmental- and sustainability work by switching completely to renewable hydropower that is locally produced in our municipality of Ydre. Long-term sustainability and care for our local environment and surroundings are two of our fundamental core values. Therefore, the decision to move to a renewable energy source, locally produced in the hydropower stations Forsnäs and Visskvarn situated only a few kilometers from our production center and headquarters, was easy.

Sustainable energy from right outside our doorstep

The beautiful river Bulsjöån runs with its clear water just outside Träullits doorstep and further through Ydre, connecting the lakes Västra Lägern, Östra Lägern, and Sommen. The active hydropower stations are located where the river and lakes intersect, generating the sustainable and renewable energy that powers Träullit’s entire business.

Close cooperation together with our surrounding nature

Our electricity supplier, Tranås Energi, has continuously worked to modify its facilities to minimize their impact on the surrounding biotopes. The geological and biological values in and adjacent to Bulsjöån are of high appraise; the watercourse is appointed as nationally valuable from the perspective of nature conservation and fisheries management. This is due to Bulsjöån’s exceptional water quality, naturalness, and being home to several red-listed species such as inland trout, freshwater pearl mussel, kingfisher, and otter. Träullit is proud to support active environmental efforts that promote biodiversity and ensures a sustainable habitat, today and tomorrow.

Open pathways for fish for the first time in over 100 years

For several years, Tranås Energi has actively worked to create fishways between the lakes Västra Lägern, Östra Lägern, and Sommen: a waterway that has been closed for more than 100 years. However, this is now changing.

The intersection points and power stations have one by one been modified with the addition of fishways in the form of fish ladders and steps. These structures facilitate fishes’ natural migration as well as movements between the waters as it enables fish to pass around the barriers by swimming and leaping up a series of low steps into the waters on the other side. Only a millpond remains until free passage has been created for the fish to wander upstream and back — something that has not been possible for more than a century.
