VELUX comfort venting Modular Skylights meet the requirements of the harmonised standard EN 60335-2-103 (2015). Therefore, comfort venting skylights can be installed within reach, i.e. at installation heights below 2.5 m above floor level (inside) and ground level (outside). We recommend that you observe national regulations and consider if the planned specific use of the building requires additional safety measures that must be applied by the installer/user to prevent serious injury. For more details and information on smoke venting Modular Skylights, please refer to the Technical Handbook and the safety guidelines delivered with each product. If VELUX roller blinds are installed, please observe recommendations.

VELUX roller blinds have a recommended minimum installation height of 2.5 m above floor level (inside) and ground level (outside). In case of installation below that level, safety measures must be applied by the installer/user to prevent serious injury. No instruction or measure can eliminate the inherent hazards resulting from installation heights below 2.5 m.
