Windows and Entrance Doors
We use thermally insulated resin window frames with double glazing (argon gas-filled, Low-E glass) or triple glazing (argon gas-filled, Low-E glass).
Alternatively, aluminum-wood hybrid insulated sash frames with triple glazing (argon gas-filled, Low-E glass) are also available.

Entrance doors are either pre-fabricated insulated aluminum-resin composite doors with double locks, or custom-made wooden insulated doors, also featuring double-lock systems.
