External roller shutters made in the INTEGRO flush-mounted system are intended to be used in newly erected buildings as well as the existing ones which do not require any changes in the lintel area.
After completing all facade works, the roller shutter box remains invisible, fitting into the facade of the building and being its integral part at the same time.
This system shows high thermal and acoustic properties confirmed by a certificate issued by the Passive House Institute in Darmstadt.
