From the time I ordered my custom window till the time it was delivered everything went well. They emailed that my order was received and paid for, emailed me - thanking me for the order - and that the order was in their system and a scheduled delivery date. They then emailed when the window was ready for delivery (the previous day). On the morning of the delivery, I was sent a tracking link - via text message - that showed how far the delivery was and where I was in the queue! Window was delivered as promised on time, undamaged by a very polite delivery guy. I wish all my purchase experiences for building products was this easy and carefree!!

There are differences in how air passes through the openings, depending on how each type of window is made. Most hinged windows open halfway, so air can pass through half of the opening. With conventional aluminum sliding windows, half of the window is closed or overlapped, so the windows provide less ventilation. However, Alusys aluminum sliding windows are designed to allow both windows to open simultaneously, allowing maximum ventilation from the sliding window. This factor is important in Middle Eastern countries such as Iran, which have hot summers

These windows and doors are a new generation of door and window systems that offer a new solution for providing advanced technologies and a high quality system for homes. In addition, these systems are a good option for covering large openings due to the optimal design and numerous innovations that have been used in the design of these systems. Also, due to their diverse capabilities and high efficiency, they increase the ability of architects to design and create very beautiful constructions.

Both sliding and hinged windows are energy efficient, but there is a difference between the two options. Since you must be able to open an aluminum sliding window, the sealants must be somewhat flexible so that the window can move easily on the rails. But the hinged window sealant is not flexible. While both window options are energy efficient, hinged windows are more energy efficient because they are not flexible in design.
