Light spill or light pollution is excessive, misdirected, or obtrusive artificial light, often emitted from buildings. If there is too much light pollution, it can wash out starlight in the night sky, interfere with astronomical research and disrupts ecosystems.

The householders are focused on saving energy and maintaining a comfortable internal environment. Overall though, in many cases the condensation does not last long and a little heat from the sun warms the outer glass enough to evaporate the moisture, a gentle breeze or wind will also do the same job.

Haze is an optical phenomenon which makes the glass look like it is covered in a very fine, uniform layer of dust when viewed from an oblique angle or viewed under strong light incident on the glass at an oblique angle. Our original Pilkington K Glass™ can, under certain lighting conditions, display this phenomenon to a limited extent.

How is toughened glass defined? Toughened glass is defined in BS EN 12150-1: 2015: Glass in building – Thermally toughened soda lime silicate safety glass. In this standard, it is defined as:

The U value for glass is determined in accordance with BS EN 673: Glass in building - Determination of thermal transmittance (U value) - Calculation method.

BS 6206 has now been superseded and replaced by EN 12600. Marking of safety glass has now changed. Please see BS 6262 Part 4 for requirements. EN 12600 defines the term ‘breaks safely’ by reference to the outcome of the impact test.

Pilkington Mirai™ has 52% less total embodied carbon when compared to standard float glass produced by Pilkington UK. The glass offers the lowest carbon alternative to regular float glass on the market, with no difference in performance, quality, or aesthetic appearance.

Sir Alastair and his R&D team spent seven years and £28 million of investment, which equates to £150 million in today’s money, developing the technique and building the float process machine.

NSG Group, known for its Pilkington glass products, will introduce its new HomeComfort range at Glasstec 2024. The event, taking place from October 22 to 25 at the Messe in Düsseldorf, will highlight these products designed to enhance home comfort, alongside NSG Group’s ongoing make change™ sustainability initiatives.

Low-e glass such as glass from the Pilkington K Glass™ Range and Pilkington Optitherm™ Range have an invisible coating which dramatically reduces heat transfer and reflects interior heat back into your room.
