1.1. Vocabulary concept

Window-frame

Framing fixed in the masonry on which will be fixed an opening (door or window) or a frame (fixed window). The frame material can be wood, PVC or metal.

Glazing bead

Removable profile fixed to the frame (opening or frame) of a window in order to hold the glazing in the rebate of the frame. With this glazing bead is placed a seal (putty, rubber or silicone) which allows the sealing of the frame.

Clear glass

Glass surface visible from an opening (opening or frame) located between the edges of the glazing beads without the gasket.

1.2. Taking measurements

HPRA

High Performance Resin adhesive
Adhesive with excellent heat resistance, the adhesion of which to the support is ensured by a physical bond between the glazing and the film.

CDA

Clear Distorsion Adhesive
In addition to excellent heat resistance, this adhesive offers great visual clarity. With low initial adhesion, the chemical bond between the glazing and the film becomes very strong, after the drying time, ensuring a long service life.

PSA

Pressure Sensitive Adhesive
Adhesive that requires pressure during installation to trigger a mechanical link between the glazing and the glazing film. This type of adhesive is used by security films.

RPSA

Reduced-tack Pressure Sensitive Adhesive
Adhesive that requires pressure during installation to trigger a mechanical link between the glazing and the adhesive film. On the other hand, the adhesion strength is lower in order to allow easy removal without leaving any adhesive residue on the support.

Ultraviolet Radiation

High energy radiation of the electromagnetic spectrum with wavelengths between 190 and 380 nm.
UVc - Absorbed by the ozone layer
UVb - Partly filtered by the atmosphere
UVa - Transmitted by the atmosphere and glass

Visible Light

Visible part of the electromagnetic spectrum covering all colors from purple to red with wavelengths between 380 and 780 nm.

Infrared radiation

Sum of visible and invisible radiation from the sun partially absorbed by matter and re-emits as long wavelength heat.
IRa - 780 à 1400 nm
IRb - 1400 à 2500 nm

% Visible light transmission (VLT)

Part of the electromagnetic spectrum with wavelengths between 380 and 780 nm (or visible light), transmitted through the glazing towards the inside.

% Reflection of visible light

Part of the electromagnetic spectrum with wavelengths between 380 and 780 nm (or visible light), reflected by the glazing.

Low emissivity value

Ability of a material to re-emit absorbed far infrared. The lower the emissivity value (on an absolute scale of 0 to 1), the better the insulation against heat loss from the glazing system. With a thermal camera in indoor shooting, a Kryo low emissivity film becomes an infrared mirror.

Coefficient of thermal transmission or U value winter

Measurement of heat transfer on each side of the glazing between the interior and the exterior. The lower the U value, the less heat transfer for better thermal insulation. Value expressed in W / m²K or W / m²C according to standard EN673.

Total energy transmission coefficient or Solar g-value

Sum of solar energy transmitted directly and by retransmission or reverberation to the interior of the building. On an absolute scale of 0 to 1, the lower the coefficient, the better the sun protection.

Shading coefficient or b-value

Ratio of solar energy transmission between glazing with adhesive film and bare glazing. The lower the value, the better the shading effect of the glazing.

% Transmission of solar energy

Amount of solar energy entering a building through glazing. This includes wavelengths between 280nm and 2500nm (UV, Visible light and infrared).

% Solar energy reflection

Amount of solar energy reflected by the glazing towards the outside of the building. This includes wavelengths between 280nm and 2500nm (UV, Visible light and infrared).

% Absorption of solar energy

Amount of solar energy absorbed by the glazing and converted into heat. This includes wavelengths between 280nm and 2500nm (UV, Visible light and infrared).

% Total solar energy rejected

Value opposite to the solar g factor which measures the capacity of an adhesive film for glazing to reject total solar energy (visible light, infrared and UV) towards the outside of the building.

% Ultraviolet transmission

Part of the electromagnetic spectrum with wavelengths between 280 and 380 nm and transmitted through the glazing to the interior of the building.

Compliance with standard EN 12600

Resistance to pendulum impact, the classification of which depends on the type of glass breakage.
Class A: breaking mode of an annealed glass,
Class B: breaking mode of a laminated glass,
Class C: breaking mode of a tempered glass.

Compliance with standard EN 356

Resistance of a security film to attempted break-ins or vandalism depending on whether or not an object has passed through the glazing.
Anti-vandalism classification P1A to P5A
Break-in classification P6B to P8B

Limited warranty

The limited warranty covers a period listed on the technical sheets for installation on vertical glazing, halved for inclined planes.
The limited warranty covers installations on glass substrates only and is limited to the market value of the film, and excludes all costs associated with removing or replacing the product. Changes in appearance due to normal aging are not included in this limited warranty. For information refer to the Terms of Sales.
