BREEAM – Building Research Establishment Environmental Assessment Method, BREEAM, is an established and international environmental certification system for comparisons of buildings’ environmental performance. The system is ultimately used for commercial buildings. Environmental performance is assessed in various areas with minimum requirements for project management, the building’s energy use, indoor climate with ventilation and lighting, water management, waste management and land use and impact on the local environment.
Electrochromism – A phenomenon in which the color or transparency of a material changes when an electrical voltage is applied.
Electrolyte – A substance containing ions with electrically conductive ability.
EMC-standard – Acronym for electromagnetic compatibility. Limits on emissions and immunity as well as various test methods are described in EMC standards in order to ensure that electrical appliances and electrical equipment do not cause interference or be disturbed by other appliances or equipment.
FreeForm®-hubb – Installations for cutting, contacting and glass lamination that are established in significant main markets in order to, through geographical proximity to the end customer, achieve more efficient distribution and lower transport costs.
g-value – The total percentage of solar energy that is passed through the glass, expressed as a percentage.
IGU – Insulated Glass Unit (IGU), also called insulating glass, is a glazing unit consisting of two or more flat glass sheets with a certain mutual distance joined at the edge so that the space between the glass sheets is completely closed off from the surrounding atmosphere. Used to improve the thermal insulation capacity of e.g. windows.
LEED – Leadership in Energy and Environmental Design, LEED, is an established and international environmental certification system for comparisons of buildings’ environmental performance. The system is used for all types of buildings.
Light transmission (LT) – The percentage of light that passes through the glass, expressed as a percentage.
Nickel Oxide (NiOx) – Oxidized form of the metallic element nickel.
PET – Polyethylene terephthalate, PET, is a semi-crystalline thermoplastic polyester.
Polymer Dispersed Liquid Crystal Device (PDLC) – An alternative technique for changing the light transmission in glass.
R2R-process – A production technique in which a rolled plastic film is transferred to another roll in a vacuum chamber, while the exposed film obtains a nano-thin surface coating by sputtering.
Sputtering – A physical method of forcing atoms out of a material to create nano-thin coatings on an object. The method means that a radiation target, the substance you want to deposit as a thin film, is bombarded with fast and heavy ions, which causes atoms and molecules to detach from the surface of the radiation target and end up on the substrate, which you want to coat with a film.
Suspended Particle Device (SPD) – An alternative technique for changing the light transmission in glass.
U-value – Also called the throughput coefficient and is a property physical parameter that measures how good insulation an entire property part, for example a wall, has. The U-value is equivalent to the inverted thermal conductivity value of a material and is expressed in watts per square meter and kelvin, W / (m2 * K). The lower the U-value of a window, the more insulated it is. Windows with a U-value of less than 1.2 and 0.9, respectively, are classified as energy windows and energy class A, respectively.
Efficiency for solar cells – A measure of the proportion of incident solar radiation that is converted into electricity.
Tungsten Oxide (WOx) – Oxidized form of the metallic element wolfram.
