Green public procurement specification for general construction and flooring adhesives. The goal of the specification is to set to set a hierarchy of flooring covering preferences, establish minimum environmental goals for flooring installations in state properties, and provide recommendations for additional aspects of flooring performance, cleaning and maintenance for a healthier indoor environment.

In January 2019, the California Building Standards Commission unanimously approved changes to the state building codes proposed by the California Office of the State Fire Marshal. The changes allow use of polystyrene insulation without flame retardants below a concrete slab-on-grade. These changes would maintain fire safety while improving human and environmental health.  This fact sheet details the key considerations for implementation of a policy on allowing flame retardant-free insulation within a building code, and the associated health and technical considerations.

At face value, cabinetry may seem to be made of one type of wood, but its construction is much more complex. Many prefabricated cabinets are built using a combination of three or more wood composites and veneers, which typically use toxic glues containing formaldehyde, a known human carcinogen.

By comparing the material contents and construction in prefabricated cabinets, we created a spectrum that indicates the relationship between affordability and health. We typically consider the health effects during all phases of product development, but these diagrams are focused on the health effects during installation and inhabitation.

Currently, prefabricated cabinets are composed of 5%-30% healthier materials. Designers can increase this percentage by requesting manufacturers to build with NAF (no added formaldehyde) composite woods. This often comes with an increased price. Our Composite Wood Product and Spec Guidance gives a range of healthier substitutions.

This guidance document aims to give an overview of potential hazardous substances that might occur in construction products and when appearing as waste need attention during renovation and demolition activities. Focus in this guideline is on hazardous substances regulated by EU or international agreements or national legislation.

Although the present legislation restricts the use of many hazardous substances in new building products, there is a considerable concern for compounds present in old construction products, since their presence in construction and demolition waste may limit the recyclability of the material and potentially cause waste management problems. One group of substances that has recently received attention are persistent organic pollutants (POP substances) such as e.g. some brominated flame retardants.

Important characteristic of the construction and building products is the relatively long life span. Because of long lifespan the restricted substances will enter the waste stream many decades after a ban has been placed on their use and they can therefore be found in renovation or demolition waste for a long time. Many of these substances provide important functionality in a wide range of products, e.g. flame retardants.

Besides hazardous substances also degradation in composition and quality aspects (e.g. mould) of construction products needs to be considered.

Tarkett have introduced an eco-innovation programme with the aim of providing more comfortable, healthy and people-friendly indoor spaces without compromising performance and design experience. Key initiatives include:

• Phthalate free technology in their New Generation Vinyl flooring;
• Low VOC emissions in flooring;
• ReStart Takeback and Recycling Programme, and use of recycled materials in new products.
