Sliding Sash Windows
Rehau Heritage Vertical Slider
General description and features - Two sashes built into the frame, that can slide in opposing directions and will remain in any desired position. The sub-frame, which makes up 3 sides of the window is welded at the top two corners and mechanically joined at the bottom with a sill by means of screws. The sill is sealed off at each end with an end cap to prevent water ingress into the walls of the property. The subframe can also be an all welded construction with a clip-in sill.

Cutting-edge profile design -
The three chambered sash profiles are designed with two front chambers to achieve good heat insulation characteristics and allow isolated drainage. The third chamber, allows the fitting of efficiently, designed reinforcement sections.

Seals - Each window frame contains six weather seal locator grooves, which allow for the insertion of seals between sash and frame. This creates an excellent barrier against both water and air ingress. In order to protect the brush seals against dirt and driving rain from the outside, the sub-frame is stepped twice. Furthermore, by concealing the edges of the sashes an outstanding insulation factor is achieved.
Fittings - A wide variety of standard hardware fittings may be used as the REHAU-Heritage system has been designed to accommodate as wide a range as possible so that all hardware requirements can be covered without limitation. Steel reinforced sliding latches allow the sashes to be tilted inwards to enable the window to be cleaned from the inside of the property and this facility is concealed for aesthetic and safety reasons.
These can be locked off if desired to prevent unauthorised tilting of the sash. Standard balances of 14mm or 19mm diameter may be used with the REHAU- Heritage system. It is also possible to fix all hardware into a specially designed steel or aluminium section for increased performance.

Colour
- The main profiles are extruded to REHAU's own white colour reference 159. All gaskets and Low-level co-extruded profiles are available in an aesthetically pleasing 'Silver' colour as standard, to match with the Aluminium spacer bar within standard sealed units.

Chamfered external and sculptured internal details add to the system's authenticity.
Maximum sizes - The maximum sizes for the REHAU-Heritage system are contained within the Manufacturing Instructions and are broken down into easy to use tables and vary dependent on the exposure category of the location of installation.

Areas of application
- The REHAU-Heritage Vertical Slider is designed to be used in homes and prestige installations, both newly built or in refurbishment of older buildings. It is of particular interest to those engaged in the renovation of historical or listed buildings. The introduction of the Heritage sash profiles followed extensive consultation and research with conservation bodies and housing associations.

Material
- REHAU PVC-U extruded profiles are made from REHAU's own recipe of window grade PVC-U called RAU PVC 1406 which it developed and has used with great success in all of its European window and door systems for over 25 years.
