Thermal Insulation. Heat loss is normally measured by the thermal transmittance or U-value, usually expressed in W/m 2 K. In its most basic terms, the lower the U-value, the greater the thermal insulation, however, the amount of free heat energy from the sun, the solar gain or g-value can also have a big impact.

It offers substantial improvement on thermal insulation when compared to clear float glass. It is also characterised by high solar heat gain, which means that as well as retaining heating warmth in a room, it allows high level of solar energy to enter, for warmer and brighter interiors in sunny spells, and reduced heating and lighting costs.

The standard gas in insulating glass units is dry air. The space between the glass panes can be filled with other gases that have different properties that improve the thermal resistivity. Argon and krypton are the most likely alternatives.

11 Apr 2021 Higher standards of air-tightness and thermal insulation in new build properties has meant some modern homes have become vulnerable to overheating. How glazing can help control the temperature of a home?

Our revolutionary Pilkington Spacia™ vacuum glazing technology provides unrivalled thermal performance in an ultra-thin unit that fits seamlessly into traditional and conservation properties. With this innovative unit you can retain the aesthetics by using the original frames.

These use a vacuum rather than air or argon between the two panes to achieve a similar energy efficiency performance to a highly insulating double-glazed unit, but in an even thinner profile. For example, Pilkington Spacia™ can achieve a 1.1 U g -value – the thermal performance of double glazing – while being as thin as a single glazed ...

The more thermally insulating the glass is, the lower the outer pane temperature is likely to be and the greater the risk of condensation on the external surface. In northern European countries, where levels of thermal insulation are higher than in the UK, the phenomenon is understood and accepted.

Pilkington Solar-E™ - good solar control and thermal insulation in a range of colours. Pilkington Eclipse Advantage™ Pilkington Eclipse Advantage™ is a range of high performance solar control on-line coated clear or body-tinted glass, with unique colours and low-emissivity properties.

Low-emissivity Glass What is Low-emissivity glass? 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 your windows to the cold outdoors. Low-e glass such as Pilkington K Glass™ or Pilkington Optitherm™ has an invisible coating which dramatically reduces heat transfer and reflects interior heat ...

Glass is playing an important role in society’s efforts to reduce greenhouse gas emissions and to mitigate the effects of climate change. We aim to be the global leader in innovative high-performance glass and glazing solutions, contributing to energy conservation and generation, while working safely and ethically.
