Ventilator
The Scottish Building Standards, Part I. Technical Handbook – Domestic, Appendix A Defined Terms, defines a ventilator as: ‘…a window, rooflight, grille or similar building component (and in the case of a dwelling includes a door) capable of being opened to provide ventilation.’
Short Guide, Scottish traditional shopfronts, published, on 18 April 2017 by Historic Environment Scotland, defines a ventilator as: ‘A horizontal band at the window head which is used to allow ventilation into a shop. May be of cast iron and decorative or plain. ‘Hit and miss’ ventilators can be slid across to vary the level of ventilation. Popular for fresh food shops which required higher levels of ventilation.’
