Fixed windows can be manufactured for a variety of purposes, ranging from large front screens to small quarterlights.  Units can be manufactured for specialist purposes including sacrificial glasses or windows in close proximity to high temperatures.  Alternatively, heated panels can be accommodated to prevent the window from fogging or freezing over during cold or wet conditions.

As with most of our windows, fixed windows can be manufactured with virtually any kind of glass including fire-resistant, shatter-resistant and in single or double glazed panels.  If you have an application that calls for a specific type of glass, chances are that the glass exists that will meet your requirements.

Two Panel Sliders incorporate two panels of glass.  Of these, one or both glasses can be made to slide, depending on your requirements.  Assuming that the window is viewed from the inside, this drawing shows a window with only the left glass sliding, and this shows one with the right glass sliding.  Finally, this drawing illustrates a window where both glasses slide.

Two panel sliders are usually locked by the means of a simple flap catch, but a KLT catch, slam catch or push-button catch can also be accommodated.

Three panel sliders are simply windows with three panels of glass, where one or more of the panels is made to slide.  There are five standard versions of this type of window.  Assuming that the window is viewed from the inside, and looking at the glasses from left to right, these types are:

• Fixed / Slider / Fixed,
• Slider / Fixed / Slider,
• Slider / Slider / Fixed,
• Fixed / Slider / Slider and
• All slider.

The standard sliding window catches - the flap catch, KLT catch, slam catch and push-button catch - can be accommodated, although careful consideration needs to be taken for windows where the centre glass slides.

Whilst four panel sliders can be made so that any of the four glasses are fixed or made to slide, by far the most popular version of this window is that where the centre two glasses slide and butt up to each other, as shown here.

Catches associated with this type of window are usually the flap catch, KLT catch or push-button catch.

Hinged windows are available in a variety of standard designs.  A simple hinged window is essentially a fixed window with the appropriate fittings to enable it to be hinged directly to the cabin wall.  A more popular type of hinged window incorporates two frames, one inside the other.  The inner frame is then hinged to the outer frame, along with any stays, catches or other fittings.  The outer frame can be mounted directly to the cabin wall.  A further type of hinged window is the multi-hinged window which incorporates one or more opening vents at the top of the window.  The whole window is also hinged to open.

Three standard hinges are available.  The continuous hinge comprises of interlocking sections which form the hinged edge of the window.  The advantage of this lies in its waterproof properties.  This kind of hinge requires that any adjacent corners are square.  The friction stay is a very popular choice, which enables the window to remain open in any position, alleviating the need for any other type of stay.  As with the continuous hinge, any adjacent corners must be square.  The loose hinge is a simple type of hinge which is usually used with some form of stay to keep the window open when required.

A hinged window can incorporate one of several types of catch.  A casement handle is a popular choice, whilst the security catch is a more industrial option.

A half drop window incorporates two panels of glass, arranged vertically so that the upper glass is allowed to drop behind the lower glass.  The catch used in this type of window is usually a choice from the flap catch, KLT catch or slam catch.

A variation of the half drop window is the inverted half drop, where the lower glass slides up rather than down.  This example shows such a window with our KLT catch, whilst this type uses the push-button catch and allows the sliding panel to be operated with one hand - popular with fork-lift drivers.

A final type of drop window is the full drop.  This window is one where the entire glass is seen to drop into the cavity between the inner and outer skins of a cabin wall.  A slam catch is usually used with this design.

The pivot window operates on a similar principle to a hinged window, except that instead of being hinged on one edge, the inner frame is made to pivot on a hinge midway along the edge of the window.  The window is usually locked in an open position by the means of a telescopic stay.  A casement handle or security catch is used to lock the window closed.

A composite window is one witch incorporates two or more standard types of windows, usually a fixed window and one of the opening types of window - a slider or hinge.  This example shows a composite window which is a two-panel slider above a fixed panel.  The fixed panel does not need to be limited to the lower half of the window - it could be above the slider, or even to one side of it.  Equally, the design might not incorporate a fixed panel at all - the design might call for a sliding window beneath a hinged window.

At Kellett Engineering, the vast majority of our windows are one of the standard designs shown on this page, but we are not limited to those.  This window is a double glazed fixed window in an unusual oval shape, whilst this window incorporates an unusually large radius in one corner.  Finally, this unusually shaped window uses two fixed panels, above and below a sliding window, and is designed to be installed using Claytonrite rubber.
