Glass Wiki
Building regulations, planning, warranties, guarantees and how to specify roof glazing.
Many roof light installations fall under permitted development rights and do not need a planning application — but restrictions apply. This beginner guide explains when planning permission may be required for roof lights in England.
BS 6262 is the UK code of practice for glazing in buildings. It defines critical locations, material selection and design considerations that underpin Approved Document K — essential reading for specifiers working with roof lights and structural glazing.
Safety glass is required in glazing locations where breakage could injure people. This beginner reference explains the critical locations in UK practice, the types of safety glass and how the rules apply to roof lights.
Approved Document O addresses overheating risk in new dwellings in England. Large or south-facing roof lights can increase solar gains — this reference explains Part O and how glazing design influences compliance.
Approved Document F covers ventilation in buildings. Openable roof lights can contribute to purge ventilation and background air paths — this reference explains how Part F relates to roof glazing and what specifiers should consider.
Approved Document B covers fire safety in buildings. Where roof lights pierce fire-resisting roofs or serve escape routes, glazing may need to meet fire resistance or reaction-to-fire requirements — this reference outlines the key considerations.
Approved Document L sets energy efficiency requirements for buildings in England. This reference explains what Part L covers, how compliance is demonstrated and where roof lights fit within the overall building envelope.
Approved Document K covers protection from falling, collision and impact. Roof lights sit at the intersection of overhead glazing safety, guarding and safe access — this reference explains how Part K considerations apply to skylight specification in England.
