Description
INTRODUCTION
Llumar window film from CP Films is constructed from micro-thin high clarity
polyester and various special coatings. Advanced engineering techniques are
used including multi-lamination, polyester dye impregnation, and specialised
vacuum processes such as sputtering. The film is designed to be applied to
the fiat glass of windows to enhance the performance of the glass for a variety
of purposes including safety and security, protection from solar heat and
glare, protection from fading of fabrics, insulation against winter heat
loss, provision of privacy, or simply a visually attractive finish.There
is a vast range of individual Llumar films offering a choice of performance
and visual characteristics. The specifier may select a film which satisfies
a primary requirement, e.g. security, and which may also offer a solution
to a secondary requirement, e.g. fade protection. This Specifiers Guide presents
the films in groups according to their primary performance characteristic.
Each film is then cross referenced to indicate its secondary performance
characteristics.
MANUFACTURE
The manufacturing process to create Llumar window film is as follows:Dyeing:
Base films are dip dyed in a proprietary batch process exclusive to CP Films.
Metallisation: Standard vacuum evaporation equipment is utilised.Sputtering:
High vacuum is used along with a glow discharge to create ions which bombard
the deposition material, ejecting neutral atoms on to the film surface. Several
such sources may be used sequentially during the same production run to give
multiple layers.Lamination: Standard techniques of adhesive coating and laminating
are used.Release Liners: A separate PET film is coated with release agent
and joined with the final adhesive surface of the product.
SHAPE AND SIZE
Film thicknesses vary from25 - 300 microns (1-12 thousandths of an inch)Roll
widths are available in 0.51, 1.22, and 1.52 metres widths (20, 48, and 60
inches).
WEIGHT
Polyester biaxially oriented film has a density of around 1.41 g/cm3. This
is approximately equivalent to 70.6 g/m2/50µ thick
APPEARANCE
Most Llumar window films are available for internal application, whilst certain
films are suitable for external application. Once the film is applied, it
is not easy to detect it as film.Rather the film "lends" its appearance to
the glass. The specifier may select from films which are clear, tinted, reflective,
or semi-reflective. Various colours and tints are available.
