Glazing allows natural daylight to enter buildings, which is great for wellbeing and, in work situations, productivity. It also reduces the energy required for artificial lighting.
However, it is important that the glazing enables daylight to enter without the associated heat and glare that accompanies direct sunlight.
Nowadays, there are many different kinds of glass available that can help to control the amount of heat and glare that enter a building through the glazing (and thus reduce air-conditioning energy consumption).
These include various shades of tinted glass, as well as coated glass and reflective glass.
The other kind of energy efficient glazing is the kind that prevents heat escaping through the windows, thus improving energy efficiency and reducing heating bills.
Low-emissivity glass (or low-e glass as it is commonly referred to) is a type of energy-efficient glass designed to prevent heat escaping through windows to the cold outdoors. It has an invisible coating that dramatically reduces heat transfer and reflects interior heat back into the room.
Low-e glazing can improve the energy efficiency of buildings, reduce monthly bills and decrease the size of the building’s carbon footprint.
Airlie Glass & Aluminium offers super clear toughened glass that is heated in a furnace to approximately 620°C and then rapidly cooled, increasing its strength by 4-5 times, while not affecting its visual characteristics.
This ensures high clarity and maximum transparency, while making the glass stronger, safer and giving it greater insulation capabilities, whether that’s keeping the heat and glare out, or keeping warmth in.
The glass can be manufactured in any colour or finish to suit the building’s requirements and décor.
