For Aluminum windows and doors, three types of glasses are highly recommended: float glass, laminated glass and tempered glass. You can choose a glass that matches your needs and preferences the best. In order to make the best selection, we will explain more about the type of glasses available for aluminum windows. You just have to make sure, any glasses that you choose, you have to use high quality material.

Tempered Glass: Tempered glasses are strong and safe. They are perfect for home safety. These glasses are made from standard glass that went through a thermal tempering process and this process made them four times stronger than regular glasses. Tempered glasses are not penetrable and when they are installed on your doors or windows, they can prevent break ins by trespassers and increase your home security. These glasses are resistant to bad weather conditions such as storms or heavy wind and rain. If tempered glasses break, they will break into small and safe pieces.

Float Glass: Float glasses are resistant and strong. These types of glasses have high density which make it to a great selection for your indoor and outdoor spaces, they are also energy-efficient glasses and you can use float glass to make low-E glass by covering it with metal oxides. Low-E glass keep your inside space cool by protecting it from severe sunlight, and decrease your need for using air-conditioning and bring down the level of energy cost. Also float glasses provides a shiny and cosmopolitan look.

Laminated Glass: Laminated glass is made of two or more layers of glass with one layer of resin, with PVB (polyvinyl butyral) in the middle. The PVB inside layer connect the glass panes together and create a high-resistant glass that can’t break easily. Laminated glasses are a great safety glass for aluminum windows and doors. Also, Laminated glass has soundproofing feature and prevent from penetrating UV rays to home space. This glass is very strong against different weather conditions and temperature changes but at the same time, it allow natural sunlight to shine inside the house.

Aluminum windows are very effective in decreasing the heat transfer and light infiltration and managing the inside room temperature. Aluminum frames can manage heat ad keep the rooms warm.
Aluminum windows with proper thermal performance can keep your home warm in winter because the prevent heat to get out of the room. On the other side, aluminum windows with good thermal performance also help to put the heat out of your room in summer and make a cool environment for you. Thermal performance of all windows, such as aluminium windows is calculated by their U-Values. The low U-Value indicate the better thermal performance. If you are replacing your windows, the new windows should have a U-value of 1.6 W / (m2K) or less. The best aluminium windows have a U-value less than this and it is crucial to keep in mind that this can define the good quality of a product as well. We believe the best aluminium window on the market are Genesis Warm Core Aluminium windows. They provide great thermal performance because they offer innovative technologies that can bring a remarkable change in design and performance. Your aluminium windows might get cold. There are may reasons for this incident. Your window maybe installed poorly therefore, the air is leaking through the window old your window is very old and you should consider installing a new window. Because old windows can decrease the surface temperature of your window frame and make the best condition for ice to shape.
R-Value is a measurement tool for thermal resistance, or the capability of a material to resist in front of the movement of heat.
U-Value is the thermal resistance or the amount of heat which is lost through the structure of a material. The U-Value is measured on a rate which heat moves through one square meter of a structure.
Low E glass is a type of glass with low-emissivity. As a example, a double-pane window with a low E coverage has a U-Value of about 0.36 which in another word, with 35% less heat gain or loss in compare to standard double-pane windows.
