![]() If you are unsure of the regulations that correspond with your project, it's possible to refer to the current regulations found in Europe or the United States as a way to ensure the efficacy of the solutions you have chosen for your project. Within every regulation, there are specifications that dictate every facet of design and construction and there are even certifications for products according to international testing, such as the ANSI SGCC (for laminated glass) and IGCC (for double-paned glass). In Argentina, IRAM is the regulatory body, while in Chile it's the NCH, in Europe the EN, in the US the ASTM, and so on and so forth in every country in the world. Regulations provide guidelines for executing processes correctly, be it manufacturing a product or designing and constructing and building, and eliminate the possibility of arbitrary decisions. In high towers, for example, many builders opt for a mix of the previously mentioned solutions, combining Double-paned, laminated, and tempered glass. White dots are painted on the exterior and reflect the sunlight and prevent it from passing through while black dots painted on the interior, while blocking the sun, still allow you to see everything outside the window.Īnalyzing the particulars of every project will allow you to get the most effective results from the fixtures you choose to build with. In the case of light shafts, you can use the double point technique, painting dots over a certain percentage of the glass (for example, 50% of the surface). You can choose based on the look of the glass, like adding images, or the function, like solar performance. For example, if you add white points on the glass, this will create shade spots in the interior space. Surface printing, or digital printing, consists of applying a layer of paint that permeates the glass through heating. It's three times more expensive to cool than to heat a space, making solar protection an essential factor to consider when choosing glass fixtures. ![]() The more selective a glass, the more light and less heat that it will let pass through. In areas with stronger sun exposure, it's important to avoid the overheating of the structure while at the same time allowing light to enter.įor this, you should research glass selectivity, choosing a glass fixture that filters and "selects" the specific percentages of light and heat that will enter the interior space. Solar rays emit both heat and light energy. In special applications, you can use monolithic glass fixtures but they should be thermally treated. ![]() The Importance of Double-Paned Glass in Every Projectīefore seeking out more specific results, it's important to understand that double-paned windows are a minimum requirement to ensure the efficiency of glass fixtures in a project, especially in terms of the thermal transmittance and sun protection required by the structure based on its location and orientation.
