The Sun-X 'MT' range grows!
Introducing Sun-X MT70E! The ultimate UV window film for UV protection, winter heat retention, and summer heat rejection, crucially, with a non-reflective finish for historic and/or listed buildings.
The Sun-X 'MT' range of museum-grade UV window films has been trusted for over 30 years to protect furnishings and artwork in historic properties from damage caused by sunlight. The 'MT' stands for 'museum transmission', i.e. a guarantee that the window film performs to exact requirements set by the museum industry, started by Garry Thomson, Head of the Scientific Department at the National Gallery from 1960-1985. The 'Thomson specification' sets out parameters that UV window filters must transmit below certain levels at three different points on the UV spectrum (in particular between 300-400 nanometers), as well as an overall reading of UV transmission being below 50 microwatts per lumen. The former requires a specialist piece of equipment, the latter just a hand-held UV meter. If a product is in the Sun-X 'MT' range, it means it is tested at least annually to ensure it meets these standards. Simply stating a film reduces UV by (eg) 99%, does not mean it is museum-grade, and indeed, probably isn't.
The new MT70E is a ground-breaking combination of the following elements:
- Museum-grade UV filtration (responsible for rotting, and 40% of fading)
- 40% improvement in the insulating 'U' value of single glazing
- over 40% reduction in solar heat gain - more comfortable in summer, plus heat is 25% responsible for fading
- exceptionally high visible light transmission - will not noticeably darken the room, but will provide additional protection against damage caused by
visible light (also 25% responsible for fading)
- non-reflective neutral finish - will not alter the external appearance, perfect for listed buildings
