We equipped our entire house with insect protection last week. The lift-and-slide doors received pleated sliding doors, and our windows also got sliding pleats because we always wanted to have the option, for example, to pass something through the window/to air out a blanket at the window, etc. Additionally, we had all the windows made because I didn't want to decide between individual windows which one to open and which not to... and that was the right decision; we've had all the windows open at night for days now.
These are aluminum frames with fiberglass insect protection. For 3 lift-and-slide doors + 14 windows, including delivery and installation, we paid around €2500. I discovered the company via Instagram through a random promotional ad from a person, with a discount promotion :)
