http://butler-bowler.co.uk/index.php/wooden-windows/tilt-turn-windows | At Butler Bowler, we offer triple glazed timber windows, tilt and turn windows. This window combines perfect performance parameters and a low heat transfer coefficient.

1. Tilt & Turn Windows
Our tilt and turn casement option has been developed
& tested to meet ‘Passiv Haus Standard’. If you are
requiring optimum performance this is the solution
you require.
This window combines perfect performance
parameters and a very low heat transfer coefficient.
The overall heat transfer coefficient value for the test
window achieved Uw = 0,8 W/m2K, which means that
the window can be used for high performance eco
house construction.
The design also provides increased acoustic performance which insulates 34-db as standard with an
option to sound insulate up to 42-db with enhanced glazing options.

2. Features
High performance German WINKHAUS Tilt & turn hinges fitted to allow for maximum
performance and durability.
The tilt position allows the window to hinge from the bottom and partially open for ventilation
and the turn allows the window to fully open from the side.
Locking handles are fitted as standard in a range of finishes. A concealed ventilation system can
be incorporated for compliance with Part L.
Our high performance paints and stains will maximise the life of your windows allowing
maximum duration between maintenance.
Unlike re-painting in the past the re-application of finish does not require laborious scraping and
sanding. Modern micro-porous paint systems allow the timber to breathe preserving the
integrity of the wood. When the time comes a light sanding over the window will provide a key
to reapply the top coat.
The Options
Angled Head - Angled windows ideal for screens and atriums for modern architectural designs.
Arched Head - A gothic arched effect common on older buildings and barns
Concealed Restrictor - Ironmongery fitted to the sash and frame which enables constraint on the
opening of the window.
Curved Head - A curved or rounded effect on windows, bullseye and oval windows are variant of the
same theme.
Dummy Sashes - A non-opening light where sightlines look as though a sash is fitted in the frame.
Flying mullion option - Used on 2 light narrow windows where fire escape is required. The mullion is
fitted to the sash allowing maximum clearance.
Large Sashes / Screens - Significantly larger sashes can be designed than for casements. Gives a clean
look which maximises glass area.
Night Vents - A device with a secondary keep position for locking cams. Allows windows to be ajar whilst
still locked.
Sliding Sash Look-a-like - A planted on section on side hung windows that gives a sliding sash horn
effect.
