REQUIREMENTS FOR DAYLIGHT

To provide adequate levels of natural light, VELUX recommends

that the daylight area be at least 15 % of the ﬂoor area.

In Scotland every apartment must have a window or windows of an

aggregate glazed area equal to at least 1/15th of the ﬂoor area of

the apartment and situated in an external wall or roof.

SAFETY GLASS

The Building Regulations state that if glass is less than 800 mm

from the ﬂoor then glazing units with safety glass must be installed.

VELUX also recommends that where windows are installed at high

level in eg public places, the inner pane be speciﬁed as laminated

glass. This means that if the glass is broken the lamination will hold

the glass in place preventing it from falling. This is of particular

importance for schools, games halls, conference centres etc.

For optimum performance VELUX recommends the use of

glazing variants --73, --60 and --65 (see pages 136-137).
