It is obvious that you want the highest glass quality when buying a glass roof access hatch or roof light. Of course, including the best insulation values to comply with your project’s standards.
No wonder you should learn to exercise caution when it comes to choosing the ideal glass specification for windows. In this simple guide, we will take you through the difference between standard glass, laminated glass and walkon glass.
Starting us off is the standard double glass that has excellent insulating properties, which are comparable with HR. The glass is ‘Heat Strength Toughened,’ which means that it was tempered by means of thermal treatment. This gives the glass its special properties. It is extra strong, resistant to larger temperature differences and safer.
Standard double glass also boasts special low E coating for better thermal efficiency. The inner sheet of the glass has an invisible low E coating that ensures less loss of warmth. This means that the warmth stays out in the summer and in during the winter, while the light transmission remains the same.
For those who want better insulation, then there is nothing wrong with choosing triple glass. This consists of three glass sheets with two argon-filled cavities. That way, you can achieve the standard needed for the passive home standard. The loss of warmth, expressed in U value must in that case be below 0.8 W/m2K.
Last but not least is laminated glass or multi-layered glass. In this case, the glass is composed of individual glass sheets with transparent foil in between. If the glass breaks, the foil holds the glass together, preventing large holes.
As for the structure of laminated glass, it is determined by the thickness of the glass sheets and the foil in between. Multiple layers of foil can be applied. The maximum size of laminated glass is smaller than that of double and triple glass, where the maximum length of a horizontal glass panel for double and triple glass.
Now that you have insights into the available glass specification for windows, it is time to choose the ideal one for your needs. Well, the standards for the use of glass differ per country as well as per application. That’s why you should never hesitate to get advice from professionals to ensure you buy the ideal window glass for your building.
