Rooflights and roof hatches – Performance characteristics for energy efficiency and resistance to selected environmental conditions – Assessment methods and specification of results cen:proj:79547

Scope

This European Standard specifies the assessment methods for the determination of the performance characteristics for energy efficiency and resistance to selected environmental conditions of rooflights and roof hatches to be used on upstands in flat and slightly inclined roofs.

This European Standard specifies the assessment methods for :
• radiation and heat transfer
• resistance to passage of water and air
• sound transfer

This European Standard applies to rooflights and roof hatches with upstands as well as rooflights and roof hatches supplied without
an upstand, intended for use on upstands.
This European standard applies to fully factory assembled individual rooflights and roof hatches which are supplied as one unit as well as to continuous rooflights that are made from more than one prefabricated sections to be assembled onsite.

This European Standard does not apply to:
• doors, gates and barriers
