This document specifies characteristics for individual plastic rooflights. These rooflights have translucent parts made of plastic materials (e.g. GF-UP, PC, PMMA, PVC) which serve the primary purpose of introducing daylight.

This document applies to individual plastic rooflights with upstands made of e.g. GF-UP, PVC, steel, aluminium or wood and to individual plastic rooflights without upstand, intended for use on upstands. These individual plastic rooflights are intended for installation in flat and slightly inclined roofs.

This document applies to individual plastic rooflights with a rectangular or circular ground plan (see Figures 1 and 2), with an opening span (width) or diameter not larger than 2,5 m and an opening length not larger than 3,0 m. This document does not cover rooflights which contribute to the load-bearing or stiffness of the roof itself.

This document applies to individual plastic rooflights without upstand, where a single manufacturer provides all components of the rooflight and individual plastic rooflights with upstand, where a single manufacturer provides all components of the rooflight with upstand, which are bought in a single purchase.

This document applies to rooflights with one or several translucent parts.

Individual plastic rooflights can be opened by means of opening devices in one or more parts for ventilation.

The possible additional functions of day to day ventilation, smoke and heat ventilation e.g. in case of fire in accordance with EN 12101-2 and roof access, are outside the scope of this document.

This document does not apply to:

— "Individual glass rooflights" acc. to prEN 1873-2

— "Continuous plastic rooflights" according to prEN 14963-1 and "Continuous glass rooflights" according to prEN 14963-2

— "Roof windows" according to EN 14351-1

NOTE An indicative list of provisions for a proper application, use and maintenance of individual plastic rooflights is presented in Annex A.

This document specifies characteristics for continuous plastic rooflights. These rooflights have translucent parts made of plastic materials (e.g. GF-UP, PC, PMMA, PVC) with and without filling material, with or without support elements, which serve the primary purpose of introducing daylight.

This document applies to continuous plastic rooflights with upstands made of e.g. GF-UP, PVC, steel, aluminium, wood or concrete and to continuous plastic rooflights without upstand, intended for use on upstands. These continuous plastic rooflights are intended for installation in flat and slightly inclined roofs as prefabricated building elements.

This document applies to continuous plastic rooflights when a single manufacturer provides all elements of the rooflight for assembly on the roof, which are bought in a single purchase.

This document deals with continuous plastic rooflights manufactured as follows:

a) with support elements:

— symmetrical, angled, curved or flat (see Figures 1 and 4);

— constructed with support elements parallel to the span and with a rectangular ground plan;

b) without support elements:

— symmetrical, angled or curved (see Figures 2 and 5) with an angle α not more than 45° (measured to the horizontal at the line of fixing, see Figure 3).

This document applies to continuous plastic rooflights, including barrel vault rooflights, with a rectangular ground plan of plastic translucent part installed in roofs, with a minimum distance of b/3 (b = effective span of rooflights, corresponding to the light opening) between each other. The upstands may be self-supporting or non-self-supporting.

This document does not apply to:

— "Individual plastic rooflights" according to prEN 1873-1 and "Individual glass rooflights" according to prEN 1873-2;

— "Roof hatches" according to prEN 1873-3;

— "Continuous glass rooflights" according to prEN 14963-2;

— "Roof windows" according to EN 14351-1.

This document does not include calculation with regard to works, design requirements and installation techniques.

The possible additional functions of day to day ventilation, smoke and heat exhaust ventilation e.g. in case of fire in accordance to EN 12101-2, roof access, and/or slinging point e.g. in accordance to EN 795 are outside the scope of this document.

NOTE An indicative list of provisions for a proper application, use and maintenance of continuous plastic rooflights is presented in Annex A.
