The type of glass is an important feature to consider when choosing windows. It is recommended to choose windows with at least double glazing. It is similarly important to consider whether the type of glass and glass system offers the right level of insulation. In the case of double-glazing, without any further insulation increasing features, the U-value will be around 2.8-3. If at least one panel has a very thin film metal coating, this value goes down to 1.4. This glass called low emissivity glass commonly known as Low-E glass. In cases where argon is used between the two panels, the U-value lowers to be around 1.1. The lower the U-value the better the glass system is as the U-value is used to measure the glass system’s ability to retain constant temperature within the house. With triple-glazing where at least two glass panels are Low-E glass the U-value can be further decreased, the thermo-performance of the glass system increased.
Our windows are made with double-layered glazing
A seamless bridge between the inside and out, LightBridge is a revolution in window technology. While ordinary glass has high levels of heat gain and heat loss, LightBridge TM double glazed units have an enclosed Low-E coating which actively insulates your home up to 77% better than ordinary glass.
LightBridge TM is also available in a range of levels of enhanced security, noise reduction, and UV protection – putting the power back in your hands to make your home your sanctuary.
Sound attenuation is particularly important in the vicinity of noise sources such as high traffic roads, airports, plants, loud neighbors. The sound-absorbing ability is determined by the so-called. Rw value that is measured in decibels (dB). The higher the Rw value is, the better the noise protection, the more the glass filters the adverse effects of noise. The basic two-layered glass structure’s sound-absorbing property is Rw=32dB, which can be enough in an average traffic-congested residential area. However, this can be further increased to even Rw=38-42dB if one does not necessarily want to listen to the music of the parties from their neighbors.
It is very important to buy windows with the right insulating ability because our choice will have an impact on our energy bill and later when we sell houses, we may have to present an energy certificate. The more stars one can achieve on the energy certificate the better the rating of the house becomes, thus the value of the house grows as well.
The U value shows the thermal insulation and thermal conductivity of the window, the unit of measure is W/m2K. The smaller the U value is the better the thermal insulation ability is.
Most burglaries are attempted through windows and balcony doors, so it is especially important that each window meets the technical requirements of anti-burglary protection. In addition to the circular locking points placed in the windows and doors, we recommend glued safety glazing, which can be achieved by gluing two or more glass sheets together. There are film layered and glued in between these glass sheets that interlock each other to prevent penetration and bread the glass.
