Series 1 Reversible Flush Casement Window
The Hybrid Reversible Flush Casement system is an 83mm high performance window system that achieves very high thermal insulation values providing low U Values well below the current and anticipated future Building Regulation requirements.
Comprising the insulating benefits of timber on the inside and the durability of aluminium on the outside, the system includes top hung, top swing, side hung, side swing and fixed light combination windows.
Glazing
Double glazing is standard and should be carried out to the recommendations of BS6262. A variety of glass options are available to maximise thermal and acoustic performance. The glazing is inserted between the aluminium and timber frames for maximum security.
Site Installation
Site fixing of finished frames should take into account all applicable standards with regard to both the method employed and safe working practices.
Frame fixings should be suitable for the purpose given site conditions, live loads and materials into which the installation is to be made. If in doubt, please check with your fixings supplier regarding type and method to be used.
Testing
The Hybrid Reversible Flush Casement Window has been tested in accordance with BS6375 Part 1: 2004 (performance of windows and doors - classification of weathertightness and guidance on selection and specification).
The Hybrid Reversible Flush Casement Window has also been tested to BS7950 for security.
Test reports for individual window configurations are available on request.
Separate figures are available for Thermal U-values depending on type of window configuration, frame and glazing material.
Size Capabilities
Size limitations for each type of window vary. The following schedule is an indication of the HYBRID system capabilities:
Top Swing/Hung - O/Out 1200 W x 1200 H
Side Swing/Hung - O/Out 600 W x 1200 H
Multi-lights: all mullions and transoms over 1200mm high or wide should be checked for Ixx value stability to loadings provided by the specifier, or to BS6399 part 2:1997. The above schedule is based on nominal test results and assumes that adequate care regarding the location and exposure of the window is taken by the fabricator.
Please refer to manual for hardware limitations.
Thermal Performance
Thermal performance of our systems depend on too many variables to determine a simple statement. Varying standards of insulated glazing units, profile selection, product size and mullion spacing combine to provide a unique 'U' value per window, door or curtain wall facade. At Senior Architectural Systems we use the most up to date designs and materials in order to offer the highest performance systems and products on offer in the UK. To determine the thermal performance of a specific proposed installation please consult your chosen supplier or Senior Architectural Systems who would be pleased to undertake a specific calculation. By varying glazing specifications and system/profile selection, high insulation, specific overall 'U' values required can be achieved.
Materials
Extruded aluminium is Aluminium Alloy 6063.T6 to BS EN 755 part9: 2001
Anodizing: i) Natural (Silver) anodised to BS3897, 1991. and ii) Anolok Bronze Colour 547 anodised to BS3897, 1991. Anodising is to a minimum of 25 microns (AA25).
Powder Coating is to BS6496, 1984.
Gasketry is manufactured in accordance with BS3734 and BS7412, cat A.
Timber is certified by MPA Stuttgart with quality class BS 11, laminated according to DIN 1052 melamine glue, weather-proof and heat proof, humidity 12% +/- 2%, only lamellaes in principle free of knots are laminated.
Finishes
The external aluminium is available in anodised or powder coat. The internal timber is available in clear lacquered or water based paint.
Construction
Hybrid Reversible Flush Casement Windows are constructed using mitred joints on both the aluminium and the timber frames. Using a mechanical corner joint on the aluminium and patented dovetail keys on the timber enables the frames to be constructed without the need for complicated production processes. Integral transoms and mullions are inserted by scribing the ends and screw fix to the frame.
Opening lights are designed to be inserted directly into the outerframe using friction stays.
Fabrication
HYBRID Windows can be fabricated alongside aluminium systems with the minimum of additional equipment. Details of the cutting and jointing machinery required to fabricate HYBRID systems can be viewed in Technical Support. For any further information please contact SAS direct.
