What is the benefits of the aluminum windows?

Beside energy rating, what makes for a good window?
Ratings are just one way to assist with determining “good” windows from “bad”. Here’s a list of other things to look out for:

1.Seeing an actual window or corner sample: Corner samples will show the inner structure of the window including the number of chambers, thickness of the vinyl, and cross section the infrastructure. Many thinner profiled windows offer a sleeker profile however lack strength, durability and insulating properties as they are not as robust as they should be.

2.Ironmongery: The mechanical parts and aspects of a window are some of the first places corners are cut. Different brand and material of the ironmongery influence the durability and loading ability of a window very much. We provide different ironmongery options.

3. Glass: It is very important to know about the glass or glazing options in windows. Different combinations of glass and the coatings that can be applied to them will change the Energy Ratings of a Window.
 4. Frame: Not all upvc window frames (extrusions) are created equal. As discussed above, there are many lighter weight, thinner profiled frames on the market. All of our frames are reinforced with galvanized in the whole profile, which add strength and water tightness to the window. increase the loading ability of the window. 
5. Installation: All the engineering and quality manufacturing in the world will not help your
