Environment - Health

Laudescher has developed several ways of analysing and auditing the impact of the company's business activity on the environment. The inclusion of Laudescher products in eco-construction schemes means that the environmental impacts of a project can be anticipated and reduced while also optimising comfort and health criteria for building occupants. Life Cycle Assessment (LCA) is used to quantify the long-term environmental impacts of Laudescher products. Use of Environmental Product Declarations (EPD) provides costed and qualitative indicators on the impacts generated by our products during their life cycle. These datasheets are compliant with standard EN15804.EPD (Environmental Product Declaration) and the Life Cycle Assessment (LCA) of a product.

The life cycle of a product consists of five successive phases (raw materials, manufacturing, transport and installation, use, end of life), from the acquisition of raw materials to their disposal or potential recovery at the end of the life cycle. Life Cycle Assessment (LCA) of a product consists of evaluating the level of environmental impacts generated for each of the five stages and drawing up a quantified assessment. This assessment is included in the product's Environmental Product Declaration (EPD). Environmental consequences are numerous and varied during the life cycle of a product : impact of transport-related energy consumption, significant maintenance required by certain products, etc.
In order to make sense of these impacts, only a scientific process can objectively determine whether a product is good for the environment. Environmental Product Declarations (EPD) have been produced to allow building designers to make the best product choice based on a scientific environmental and health "passport".

An EPD provides objective quantified and qualitative indicators on the impacts generated by the product throughout its life cycle. It is produced in compliance with standard EN15804. The life cycle of a product consists of the following phases:

1. Production : includes manufacturing of the product but also the extraction, preparation and transport of the raw materials required to produce it. This phase ends when the product leaves the factory.
2. Transport : includes transport of the product from the manufacturing plant to the site where it will be used.

3. Installation : consists of the installation of the product in a building. Transport of installation waste (offcuts, consumables, etc.) is also taken into account.
4. Use : phase during which the product performs its function in the building. During the use phase, the product may be serviced, maintained or partially replaced and this is included in the environmental assessment. 5. End of life : consists of the removal of the product during a demolition, refurbishment or maintenance operation. The transport of waste produced in this phase to a recycling or disposal site is also taken into account.

Assessment of the life cycle can be used to obtain environmental impact indicators as a mean of comparing different products
• Energy resource consumption (in kg or MJ)
• Resource depletion (in kg of antimony equivalent)
• Solid waste (in kg)
• Climate change (in kg CO2 equivalent)
• Atmospheric acidification (in kg SO2 equivalent)
• Air pollution (in m3 of air required to dilute products)
• Water pollution (in m3 of water required to dilute products)
• Destruction of the stratospheric ozone layer (in kg CFC11 equivalent)
• Formation of photochemical ozone (in kg ethylene C2H2 equivalent)

• Modification of biodiversity (deleted as non-quantifiable) Added to these indicators are measurements of health and comfort impacts
• Indoor air quality
• VOC (Volatile Organic Compound) and formaldehyde emissions
• Behaviour of materials exposed to fungal and bacterial growth
• Natural radioactive emissions from construction products
• Water quality whether or not for human consumption
• Indoor humidity comfort
• Acoustic comfort
• Visual comfort
• Olfactory comfort
• Space quality

In order to compare products, it is also important to define the functional unit (m2 for a covering product or ml for a pipe for example) and the typical lifetime (or TL) for each construction product.

Health labelling

Since 1 January 2012, all new construction and decoration products sold in France must be labelled to provide information on VOC emissions.

Indoor air emissions

Construction materials, paints, wall and floor coverings and coatings, insulation products, etc. can all emit volatile pollutants which are dispersed into the air inside buildings during and after construction work.
Since 1 January 2012, all new construction and decoration products sold in France must be labelled to provide information on VOC (volatile organic compound) emissions after 28 days of testing.
Products brought to market before this date must be sold with a label from 1 September 2013 onwards.
The objective of this regulation is to inform consumers about the risks of inhalation

toxicity associated with volatile pollutants such as formaldehyde, toluene and styrene, which may result in diseases such as asthma or allergies.
The products affected by this new regulation include construction products and wall and floor coverings and coatings such as paints, varnishes, glues, adhesives, etc.
The product emission class is indicated by letters ranging from A+ (very low emissions) to C (high emissions), in line with the principle already used for household electrical appliances and vehicles.
Emission classes (regulation of 19 May 2011) Laudescher products have been tested in an independent laboratory and classed "A+"


The FSC® (Forest Stewardship Council ®) is an international independent, non-governmental and not-for-profit organisation. The aim of the FSC® is to constructively encourage forest management initiatives that are socially, environmentally and economically responsible, and to make them visible and credible through a label awarded to products from certified forests. The FSC® logo denotes a product that complies with clear and transparent specifications audited by independent certifiers. It therefore allows consumers to identify wood and wood-based products from forests managed in compliance with the sustainable development principles defined in Rio in June 1992, these principles being :
• environmentally sound ;
• socially beneficial ;
• economically prosperous ;

The FSC® Chain of Custody ensures traceability of FSC® materials during the different processing stages, from the forest to the distributor to the end consumer. CoC certification covers the manufacturing, processing and retailing operations of timber and non-timber forest products.
The CoC standard requires companies to identify the origin of the raw materials used to manufacture their FSC®-certified products and to keep FSC®-certified products separate from other products throughout the transformation process. Only groups of products manufactured from FSC® raw materials covered by a company's FSC® CoC certificate can be sold with the FSC® label. The FSC® label acts as a link between production and responsible consumption, allowing the consumer to make environmentally and socially responsible purchasing decisions. Laudescher is convinced of the long-term future of solid wood an outstanding material that the company has been working with since its foundation. Wood is a naturally legitimate material in the face of the global challenge posed by sustainable development and has established itself as a genuine solution to numerous environmental problems.


Originally known as "Pan-European Forest Certification" and now standing for the "Programme for the Endorsement of Forest Certification", PEFC is generally presented as a certification eco-label, designed to promote the sustainable management of forests. When applied to a wood or wood-based product, the logo guarantees that it includes at least 70% of wood from forests managed in compliance with the recommendations of national and regional PEFC™ entities. 9% of the world's forests, or 280 million hectares, are certified as meeting sustainable forest management criteria. Out of these 280 million hectares, 200 million are PEFC™ certified, making it the world's leading certification body in terms of surface area certified. Around a quarter of France's forests are PEFC™ certified (i.e. just under 5.06 million hectares in December 2008). PEFC™ activities cover two main areas :
• Forest certification. To certify management of a forest as sustainable, the organisation PEFC France requires that a certain number of its sustainable management rules be implemented. To ensure credibility, these rules

must be verified by an independent third party ; this is a certifying body that has itself been accredited by the COFRAC (French organisation responsible for the accreditation of laboratories and certification and inspection bodies). The forest owner undertakes to comply with a set of specifications that contain specific requirements in terms of sustainable forest management. The forest operator - responsible for felling the timber - also signs a set of specifications.
• Certification of companies in the wood-processing industry. In addition to forest certification, the PEFC™ system is used to track timber from the forest to the end user (PEFC™ wood chain of custody). For consumers, the PEFC logo on a wood product guarantees that it includes at least 70% of wood from PEFC™-certified forests. The primary objective of PEFC™ is to further expand the sustainable management of forests, and therefore to develop the world's market for wood and by-products from forests managed in accordance with its principles; as a result, the PEFC™ system has been expanded since the 2000s to take account of the diversity of the world's forests beyond the pan-European zone. It is based on the principle of subsidiarity, in other words, respect for the three main functions of the forest : economic, environmental and social.

Sound absorption

How sound behaves in a room
When a sound wave hits a surface, part of the energy is reflected, the material absorbs part of it and the rest is transmitted. The quality of sound absorption is determined by the layout of the space and the materials used.
By nature, stone wool offers excellent sound absorption properties.

Proper sound absorption
• Sound absorption controls the ambient sound pressure level in a room to create comfortable environments in which people can concentrate and work productively without noise-induced irritation or stress
• It increases speech intelligibility making presentation and conversation easier to understand
• It reduces reverberation (echoes) and the ‘cocktail party’ effect where sound levels rise uncontrolled in a room as people talk louder and louder to make themselves heard until everyone is shouting

Reaction to fire

Reaction to fire determines whether a material fuels a fire
The EU Reaction to Fire evaluation criteria (EN 13501-1) measure a material’s ignitability, rate of heat release, rate of spread

of flame, rate of smoke emission, toxic gas emission, flaming droplets/particles and/or a combination of these safety aspects.
