| Résumé : |
The external use of wood in buildings is widespread across Europe where it is valued for bath structural and aesthetic reasons. Wood is a renewable resource, with 90% of the wood consumed in Europe being grown in European forests. To enhance the appearance and extend the lifetime and use of wooden joinery (windows, doors, cladding etc.) it is typically coated with paint, varnish or stain. The two latter are often preferred since they enhance the appearance. However, their transparent nature does not protect against the damaging effects of UV light as efficiently as opaque paints. During its lifetime coated wood needs maintenance which is costly and needs to be kept to a minimum. There is a need in Europe to maximise the use of timber as a sustainable resource, and in common with all materials coated wood must extend its service life. However this raises a major challenge. The best wood coatings already last 7-10 years, although reports of even 28 years have been recorded. Coatings manufacturers constantly have to re-formulate their products in response to environmentaf legislation and such changes can easily affect durability. Products must be launched before they have been fully tested for long periods under all conditions, which introduces commercial risk. |
