Our environmental performance in the various impact categories

As a company whose products are based primarily on fossil raw materials, we have committed ourselves to a strategy of environmental efficiency. Our strategy aims to provide the function “waterproofing” while consuming the least amount of resources (raw materials, energy) and producing as little waste as possible. The long service life and long-term performance of our products and systems is an essential part of this strategy.

e have thus decided to demonstrate our specific environmental performance, or the environmental impact we create in each impact category, in relation to the functional unit “1000 m2 of membrane produced”. “Membrane” here refers to our polymeric roofing and waterproofing membranes. The calculation of the functional unit is based on the average membrane thickness.

This average is the weighted arithmetic mean thickness of all the membranes we produce. The weighting reflects the amounts of each product produced annually. Changes in production output are thus taken into account.

The functional unit takes into account every PVC and FPO membrane we produce for every field of application. Because we produce different amounts of the different products each year, the average thickness varies from year to year. The average thickness over the last four years has been as follows: 1999: 1.44 mm, 2000: 1.52 mm, 2001: 1.47 mm, 2002: 1.44 mm.
