RW 71 Insulated Window and Door System
Specification
The RW 71 Realit® window and door system focuses on thermal insulation of premises and operability. The system is resistant to any mechanical damages and adverse environmental effects. Custom EPDM gaskets with “whiskers” substantially reduce thermal losses and provide outstanding water tightness. The rational fabrication and assembly technology, as well as excellent thermal and noise insulation properties of the RW 71 insulated system ensure maximum comfort in the premises.
- The basic dimensions of the RW 71 window and door system are 71 mm for the frame and 79 mm for the vent. The assemblies can be filled with either glass panes or sandwich panels with thickness from 12 to 62 mm.
- The glazing infill is placed on special glazing supports and fixed with glazing beads processed at 90°. The glazing infill cannot move freely within the structure.
- This system is based on a combination of two aluminium profiles interconnected by two 34 mm thermal breaks made from fibreglass reinforced polyamide strips.
- The material of the breaks (polyamide with 25% glass fibre) has low thermal conductivity and guarantees high accuracy of dimensions and forms, durability, and ageing resistance.
- The multi-chambered central EPDM gasket in the RW 71 insulated window and door system ensures a high level of tightness and excellent thermal insulation.
- The RW 71 systems support assembly of a hidden vent for window elements installed into the facade. This feature simplifies the design considerably, enhances the facade appearance, and minimizes heat losses.
- The visible width of frame profiles ranges from 50 to 150 mm; the visible width of vent profiles is from 65 to 85 mm.
- The custom-designed underlying profile in the insulated window system optimises assembly of window elements, improves the tightness and thermal properties of the interface between the bottom part of the window and the aperture. This profile is versatile as it is compatible with windows of both the RW 64 and RW 71 systems, including tilt and turn, top-hung, mid-hung and hidden vent windows.
- The systems withstand temperatures in the range from -50 to +80 °C.
- The frame profile groove is 14/18 mm (Eurogroove); the vent profile groove is 15/20 mm (Eurogroove).
- All fastening elements are made from stainless steel. This material is resistant to corrosion and harsh weather conditions. Therefore, facade structures have a long service life and preserve their strength properties and original appearance.
- The system includes a custom frame that simplifies integration of a window element in a mullion/transom facade. This solution helps align the planes of the external surface of the window glass pane and the glass pane installed into the facade.
