Tilt & Turn

The Hybrid Tilt and Turn (open in) 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.

Construction

Hybrid Tilt and Turn 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.

Testing

The Hybrid Tilt and Turn 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 Tilt and Turn 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:

Tilt & Turn (Open In):
Maximum Height - 2100mm
Maximum Width - 1500mm
Minimum Height - 667mm
Minimum Width - 390mm

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 into account.

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.

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.
