Opalux® neutral grey lower mirror solar control films offer a balanced year-round
performance of good solar heat rejection with higher light transmission and additional
winter heat-saving benefits.
These neutral grey coloured films are specially metallised to allow plenty of light along with good solar control properties.
Avoiding the mirrored look of traditional solar control films, these present a pleasing architectural appearance.
These films help to reduce cooling costs and therefore Climate Change Levy liability by lightening the load on air conditioning equipment. Government and business organisations can use Opalux® solar control window films as an integral part of seeking to comply with the Carbon Reduction Commitment scheme and The Carbon Trust policies.
Opalux® Neutral Grey Lower Mirror Solar Control films are used where a neutral appearance is required, and are ideally suited to architecturally sensitive applications such as listed buildings. These films achieve good solar heat and glare control but, depending on the type chosen, can still allow vision both ways, and make less visual impact than traditional mirrored films.
The films are applied internally and, in daytime, lend the glass a neural grey lower mirror outside appearance, whilst from the inside, the visual effect, much less noticeable, is a light tint.
