Our manufacturer is not only known for producing high-quality frame profiles, but also for producing a large array of glass types. With new technologies and first-class testing facilities, our glass along with the frames that hold them, are always produced at the highest quality. This results in the possibility to produce curved edges and large glass packages with easy use and functionality, with absolutely no optical distortions.
Glass types can be combined to create double, triple and even quadruple glazing systems. Double glazing is the combination of two panes of glass separated by a cavity. As a standard, our glass cavities are pressurised with argon gas, to greatly increase the performance of the double glazing unit. Optionally, krypton gas can be applied instead, to further increase the performance of the glass system.
Our standard double glazed system is represented like this (4TMP/16Ar/4). This means the system has a 4mm pane of energy efficient glass (TMP) with a 16mm argon gas cavity (Ar) and also with a standard 4mm float. A standard double glazed unit package has a heat transfer coefficient Ug = 1.0W/(m 2 K) according to the PN-EN674*
Glass Type Options Include: float, thermo-float, colour-float, multi-float (safety, anti-burglary, bulletproof), mato-float (anti-reflective) ornament and even an electric self-obscuring glass (priva- lite). As an alternative to glass, Oknalux also has many door panel options made of PVC or Polycarbonate in a wide range of colours.
Glass Types
Low-E Glass
The ‘E’ in Low ‘E’ refers to ‘emissivity.’ Emissivity is the ability of a material to radiate energy. When glass has low emissivity, it emits low levels of radiant thermal (heat) energy. Reducing the radiant energy of one or more of the glass surfaces significantly improves a window’s insulating properties and works effectively for both hot and cold days.
As a standard, throughout all glazing combinations, Oknalux offers at least one pane of energy efficient glass (low-e glass) and is represented with the code (TMP). Low-e glass significantly reduces the heat transfer through the windows, and is a contributing factor to our low u-values throughout all our products. Our e-glass has a thermal insulation coefficient of Ug = 0.3 W/(m² K)*
Low-e coatings on glass have absolutely no effect on the visibility through the glass, and one single pane of our e-glass has a better u-value than our competitor’s double glazed system. It also makes window tinting obsolete. Low-e coatings have been developed to be ‘spectrally selective’ to affect particular wave lengths of light and not others. Our sun emits three types of solar energy; Ultraviolet (UV) light, visible light and infrared (IR) light and all occupy different parts of the solar spectrum. The differences between the three are determined by their individual wavelengths. Low-e glass reduces ultraviolet and infrared light which are the contributing factors for both fading of materials, and heat transfer into the house. The
low-e glass still allows visible light wavelengths to pass through and can reduce the amount of heat that is conducted through the glass by around 30%, compared to ordinary glass. This results in the possibility to have large window panes and feel comfortable within the space, while maximising energy savings due to minimal heat loss.
Priva-Lite
Oknalux, in association with the Saint-Gobain Glass Company are excited to introduce a modern laminated ‘Priva-lite’ glass, which can instantly change from an opaque to a transparent appearance. The Priva-lite system is a laminated glass, which has a special liquid crystal (LC) foil that when under the influence of the electric field the liquid crystals align, and the glass becomes transparent. When the electrical power source is turned off, the glass immediately returns to the opaque/matte appearance. This opaque appearance can be in 10 different textures, 12 different colours and can reduce light transmission by 77%. It gives complete privacy for both domestic and commercial use.
