With large glazing areas in architecture becoming in an increasingly desirable feature, correct specification of glass is essential. Typical ‘A rated’ glass is intended to maximise heat gain per square metre and for good reason – but when fitted into a large feature opening it’s far less suitable and can create unwanted issues of glare and heat build-up. Designed specifically for this highly popular door market, SMARTGLASS Bifold Glass offers clarity and high light transmission, yet minimises both heat loss and heat gain for optimal all year round comfort.
