PVC windows

Modern PVC windows can be used in practically every type of building.

They can be easily fitted in historic buildings, single-family homes, avant-garde office buildings, or tower blocks as well. Stylish profiles and decorative mouldings allow them to be seamlessly blended into the building’s facade and interior.

Differences in the construction of the profiles have a marked effect on the technical properties of the windows. STOLLAR PVC windows are exceptional not only for their good looks, but also for their outstanding thermal properties.
