All Brett Martin flat glass rooflight variants feature high performance glazing units with laminated inner panes as standard (as recommended by The Rooflight Association). These glazing options are available for Brett Martin Flat Glass, Circular Glass and Glass Link products.
All glass types are available with Ritec ClearShield Eco-System® easy-clean coating. Please note this coating will only offer a benefit on flat glass rooflights installed at a minimum 7° pitch.
To maintain consistency of supply Brett Martin use a variety of glass suppliers and so the values above are typical but may vary slightly from time to time.
