Opalux® bronze 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 bronze lower mirror 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 bronze lower mirror solar control films are used where a more 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 bronze lower mirror outside appearance, whilst from the inside, the visual effect, much less noticeable, is a light tint.
