Can ordinary Lualloy windows be modified with insulating glass?

Can't change, track and pulley size specifications are different, mainly due to the influence of the force structure, if forced to change, there will be problems.

If it's just because of sound insulation, there's no need to change it. Find a nearby door and window processing shop, and ask the master to help install the fully invisible sealing material (automobile grade) for the windows, and seal the gaps in five directions of the doors and windows (without affecting the push-pull switch of the doors and windows), which not only keeps warm, but also has good environmental sound insulation and dust prevention effects (80% sound insulation, 90% dust prevention, etc.). ).
