Convincing Heritage Style
REHAU Heritage windows are designed with all the traditional detailing found in period sash windows, including a deep bottom rail, slim sashes, and an optional Georgian bar. Successfully approved and installed in conservation areas REHAU Heritage Vertical Sliding Windows are suitable for any style of home. The issue of draughts with timber sash is negated with the REHAU Heritage vertical slider; triple brush steels are incorporated into the innovative system, creating a high effective method of draught proofing.
