Introduction ![A technical detail drawing labeled '1' showing a close-up section of a window frame, illustrating the proposed replacement window design.](https://images.planningportal.im/2016/09/167321.jpg) ![A detailed architectural section drawing showing a window frame and reveal detail, marked with figure number 2.](https://images.planningportal.im/2016/09/167322.jpg) REHAU Heritage is the brand name for a particular group of REHAU PVC-U window and door extruded profiles and other components collectively known as the Window 'System'. The word 'System' describes that the individual profiles and components have been designed in such a way as to be capable of being used with each other in different combinations to make a variety of window styles in different sizes. REHAU Ltd. is the 'System' designer and produces and sells the PVC-U extrusion profiles. Other components of the system such as plastic mouldings, steel reinforcements and gaskets are designed and sold by REHAU but not necessarily made by REHAU. Please note that REHAU Ltd. is not the window designer, manufacturer or installer. These functions are in the hands of the independent window fabrication and installation companies who purchase their components from REHAU Ltd., or each other. However, as the system designer, REHAU has created manufacturing guidelines, reinforcement guidelines, recommended maximum sizes, recommended installation procedures - all in an attempt to ensure that the fabrication companies manufacture and install finished products, incorporating REHAU components, that are safe and perform well in use. In most instances safety and performance criteria are taken from national standards e.g. BSI. Please see the appropriate Technical Manual for details. REHAU would therefore like to point out that because of the differing conditions and requirements of individual sites, it is the responsibility of the window designer, fabricator and installer to check the suitability of REHAU Heritage components used. Chamfered external and sculptured internal details add to the system's authenticity. The traditional design detail found throughout the REHAU Heritage system is encapsulated by the specific styling of the sash horn mouldings. ## Rehau Heritage Fitting Quality ![Technical architectural drawings showing detailed sections of window frames and hardware mechanisms.](https://images.planningportal.im/2016/09/167323.jpg) ![A grainy, black and white close-up photograph of a traditional multi-pane sash window reflecting trees.](https://images.planningportal.im/2016/09/167324.jpg) The REHAU Heritage system has been designed to accommodate all possible hardware requirements. Steel-reinforced sliding latches allow the sashes to be tilted inwards to enable the window to be cleaned from the inside of the property, yet the facility is concealed for aesthetic and safety reasons. The latches can be locked off to prevent unauthorised tilting of the sash. Standard balances of 14 mm or 19 mm diameter may be used, and it is also possible to fix all hardware into a specially designed steel or aluminium section for increased security performance. Summary of options available with the REHAU Heritage system: - Stepped frame with either mechanically jointed sill or fully welded options - Supplementary profiles and seals, including Georgian bars - A comprehensive range of additional profiles via the REHAU Tritec 60 mm casement system allow for easy and versatile installation options - Patented heritage-style horn replicates traditional timber aesthetics - A contemporary window style is available with the use of glazing bead profiles via the REHAU Tritec 60 mm casement system More information for fabricators and installers can be found in the REHAU Heritage System Description (719.600EN/657). ## Rehau Heritage Simple Construction ![Technical drawing illustrating three variations of window designs with labels indicating external and internal opening mechanisms.](https://images.planningportal.im/2016/09/167325.jpg) Fabricators and installers consistently recommend REHAU window and door systems to customers. They know they are delivering a quality product that will give full satisfaction. Our systems are specifically designed to help the installation process run as smoothly as possible. The simple construction and fitting specifications behind the REHAU Heritage Vertical Sliding Window system are described below. The system has two sashes built into the frame which slide in opposing directions and will remain in any position. A sub-frame, which makes up three sides of the window, is the most popular configuration and is welded at the top two corners whilst mechanically joined at the bottom with a sill and screws. The sill is sealed off at each end with an end cap to prevent water ingress into the walls of the property. The sub-frame can also be an all-welded construction with a clip-in sill. This detail is used in installations where stone sills are present. The three-chambered sash profiles are designed with two front chambers to achieve good heat insulation and allow isolated drainage. The third chamber allows the fitting of specifically designed reinforcement sections. Copyright Department of Local Government and the Environment.
