ARSO/TC 25/SC 1, Roof covering products
Standardization in the area of general and specific requirements and test methods for roof covering products for discontinuous laying and products for wall cladding.
The essential characteristics for wall coverings include:
- Reaction to fire (only for coverings intended for uses on walls subject to reaction to fire regulations;
- Release of formaldehyde (where relevant, according to material);
- Release of pentachlorophenol (where relevant, according to material);
- Release of other dangerous substances;
- Susceptibility to the growth of harmful micro-organisms;
- Water vapour permeability (only for coverings intended for use on walls subject to water vapour control requirements);
- Water permeability (only for coverings intended for use on walls subject to water penetration requirements)
- Thermal resistance (only for coverings intended for use on walls subject to thermal insulation requirements.
Roof covering, floor coverings and wall cladding products are used worldwide to cover roofs, floors and external walls of all types of buildings. Some of the products are used internally as well.
The various materials used include natural raw materials, like clay, natural slate and stone, combined materials like concrete, ceramics, fibre-cement and bituminous products, metals, metal faced insulated sandwich panels and plastics.
The shapes in which they are used include:
- small elements: tiles and their fittings, shingles, sidings, slates
- large elements: flat, profiled and corrugated sheets, sandwich panels, flexible sheets for waterproofing and
- accessories for inclined roofs: rooflights, roof access, roof ladders, eaves gutters and downpipes.
