New West Port Corporation Ltd. Product Specification Guide. Version 13.0
H Type Window
Timber
Hardwood, European Softwood, Laminated Softwood, Clear Faced Laminate.
Glass
Standard IGU thickness: 28mm. 4/20/4 soft coat Low E to the inner pane.
Black warm edge spacer. Argon is available to achieve lower U values.
Triple Glazing
Available up to 36mm thick. Timber beads all round must be used.
Beads
Q drained and vented bottom bead with timber to top and sides. Beads can be
mitre or butt jointed at the top. Timber beads all round are available and can
be either mitered or butt jointed. As the bottom bead is not aluminium, it can
be painted/stained to match the rest of the window.
Bead Fixing
Protec glazing machine.
Cill Extension
Standard options are 25mm, 37mm, 63mm and 87mm. Adding any of these
sizes to our frame depth of 94mm will give you your overall cill depth. Larger
cill drips are available in either softwood or hardwood, which due to the size
will also require a 15mm cill packer. We recommend hardwood whenever
possible to aid stability; this is, however, no guarantee against movement.
Please note these fall outside our normal warranties.
Hinges Spilka
Available as top hung fully reversible. Opening sashes can only be offered in
rectangular shapes with right angled corners. Part of the hinge is visible from
the outside; this can be powder coated to match the window.
Restrictor
The Spilka hinge has an integral restrictor that initially prevents the sash from
opening past approximately 100mm; this is not held in position unless an
optional anti-blow back device is fitted to the LH jamb. The restrictor is
located on the RH jamb and is released by sliding upwards.

is secured to the frame by retractable rods. Available in brown or white.

If vents are located through the sash top rail then the Vent/Canopy calculations apply. As the sash top
rail length is smaller than the frame head the overall frame will need to be a minimum of 150mm wider
to accommodate the minimum width required for the appropriate vent.
