Light Management window films fall into two categories - Light Diffuser Films and Light Blockout Films.
Light Diffuser Films
Light Diffuser Films are specially designed to offer better and more uniform light diffusion across a window or lightbox. This means that they will diffuse the sun's rays, daylight or artificial light in a more effectively measured way than a standard privacy, solar control or tinted film.
They can also be used in conjunction with a heat or glare control film to improve its performance by effectively diffusing the light, in addition to the glare control already provided. However this will convert the film to a 24 hour privacy film and you will not be able to see out through the window. That is, they will convert the glazing from transparent to translucent.
These Light Diffuser films can be used as specialist privacy films to give even more effective privacy than a standard privacy film. They are white and come in two densities - 30% light transmission (denser) or 60% light transmission (less dense) Light Blockout Films.
Light blockout films have a visible light transmission of less than 1%. This means they effectively block out daylight or artificial light through the window or lightbox, and are totally opaque.
The two films offered are white/black (adhesive on the black face) or black/white (adhesive on the white face), and can be installed to the inside face of the window or lightbox, or to the exterior face..
Some example uses would be to the windows of a museum display area to prevent any daylight coming through the glazing, or to the windows of a laboratory room or a theatre for the same effect.
To prevent light seepage between the film edge and the window frame it may be necessary to seal the edges with a black or white waterproof silicone mastic.
Exterior application may be necessary in certain circumstances from an access point of view or to prevent undue heating up of the window units from the sun, reducing any risk of unit failure through seal breakdown or thermal fracture.
Accurate selection of film requires specialist knowledge and end-users and specifiers are encouraged to consult Opalux technical department.
Where appropriate you will be connected to an Opalux approved dealer who can discuss your requirements, visit site if necessary, and provide costings for the film installation.
