Planning

10 VELUX

MINIMUM SILL HEIGHT REQUIREMENTS

The bottom frame of an opening window must be positioned at

least 0.8 m above ﬂoor level.

Restrictor locks can be used for centre-pivot windows with sills

below this level.

If the window functions as a means of escape/access, the bottom

frame must be positioned as shown on page 7.

VENTILATION

In habitable rooms fresh air must be admitted for the health and

safety of its occupants. VELUX roof windows provide both purge

(rapid) and background ventilation to meet these requirements.

Additionally mechanical extraction is required in kitchen and bath-

rooms etc to rapidly remove large volumes of aqueous vapour.

Building Regulation requirements should therefore be checked as

to the provision of the correct amount and type of ventilation for a

room depending on its size and use.
