The current harmonised European Standards EN 1873:2005 (individual rooflights of plastics) and EN 14963:2006 (continuous rooflights of plastics) will be revised in light of the new Construction Products Regulation (CPR) 2024/3110.
In the meantime, the current harmonised standards remain valid and the basis for the development of the Declarations of Performance for Rooflights.
The Importance of Declarations of Performance
The Declaration of Performance (DoP) is a mandatory document that provides information on the performance of the construction product.
The Declarations of Performance support engineers, architects, building designers and contractors to make informed design choices when planning and designing a building.
For rooflights, the DoP includes parameters such as:
- Load Resistance: Ability of the rooflights to withstand downward and upward forces, such as snow loads or wind pressure.
- Thermal Transmittance: Measure of heat transfer through the rooflights.
- Fire Performance: Including reaction to fire, resistance to fire, and external fire performance.
- Water Tightness: Ability of the rooflight to prevent water penetration.
- Sound Insulation: Ability of the rooflight to reduce airborne sound, enhancing acoustic comfort.
- Daylighting Metrics: Including solar factor and radiation properties, enhancing the occupant well-being.
