Casement Windows

Casement windows simply have sashes that open out on special hinges which use friction to keep them open in the position which you choose.  Because this type of window opens outwards and has a rebated sash which lips over the outer frame, they offer superb protection against the wind and the rain.  They can replicate any style of timber window, with openings from the side or the bottom.

If you have an eye for detail you may wish to incorporate dummy sashes in to your design.  This allows you to balance out the sight lines of an opening sash with one which has no locking mechanism or handle.  You will be surprised what a difference this can make to the look of your house.

Whatever window type you decide upon you can choose from a range of finishes which suit your home.  The ever-popular white is still favourite and gives the appearance of a freshly painted home year after year.

Your original windows may have a wood stain finish or perhaps you just want a change from white.  It is not possible to apply a stain to a UVPC window but we supply an almost unlimited supply of colours including cream, rosewood, golden oak, Irish oak, black, Chartwell green, blue or grey.  Special finishes beyond this range are also available.

The UVPC sections which are used to manufacture our products are available in two different profiles that can alter the appearance of your windows. The bevelled range has been designed to copy the traditional putty line which is used to glaze a timber window with a simple flat surface whereas the featured frame has a more finer detailing to give the appearance of a shaped timber bead used to secure the glass.

All the Ultralux casement windows come with a special type of hinge referred to as friction stay.  These clever hinges allow you to effortlessly open the window to your chosen position, once there the geometry of the hinge and friction combine to keep it in place without fear of it being caught by the wind and blown back.

There are certain legal requirements relating to your security, and in the unlikely event of a fire, we may have to fit special hinges in some rooms to allow windows to be used as an emergency exit.  You may also want to have our easy clean hinge.  This clever option allows you to slide the open window to one side so that you can safely clean the outside without climbing a ladder.  There are also restrictor hinges which may be appropriate for a child’s room or a low window where there may be a risk of someone falling.

Tilt and Turn Windows

Our most popular across main land Europe, allowing the biggest possible glass area, they open in to your house.  This can be useful if you have limited clearance outside and they are very easy to keep clean as even the outside of the glass can be washed easily from inside the room.  The locking and hinge arrangements mean you can either open this type of sash at a fixed angle to allow ventilation or you can open it from the side, giving the maximum aperture to let in as much light and air as possible.


Once your new widows are installed the component you will touch and operate most, will be the handles.  You will want them to be pleasing to both touch and look and they must compliment the feel of your décor and above all they must function perfectly time after time.  Our handles offer the very best combination of functionality and aesthetic appeal.  Each handle is offset so that when gripping the handle your knuckles are a safe distance from the frame.  When moved to the closed position it automatically locks into place against a positive stop.  Yet is simply released by the press of a button when you need to open the window.  For extra security, our handles can be dead locked with a key.  Available in white, black, polished chrome for satin chrome,  All finishes meet the corrosion  resistance requirements of BS EN 1670:1988.


Although often taken for granted glass in recent years has some amazing technological developments.  As standard your windows will have a special coating which reflects heat back in to your room and ensures that they comply with the latest building regulations relating to insulation levels. We can further improve this performance by filling the cavity between the glass with argon gas.  We can use a special glass which allows more solar heat to get in to your home.  We can offer you glass which cleans itself using the power of the sun and the rain.  If you have a south facing room with large windows you may want to consider a reflective glass which keeps it cooler on very sunny days.  Acoustic insulation is becoming of more concern and we can also offer acoustic glass to significantly enhance and improve the acoustic performance of your home.

Triple glazing is becoming more and more popular and this automatically improves the acoustic and thermal performance of your windows. We will of course as part of our commitment to quality control and safely ensure that you and your family are safe by fitting toughened or laminated glass to all doors and high-risk areas.  Rest assured that your installation under taken by Ultralux will protect you.

Traditional leaded glass can be recreated in double glazed units and we will take care to replicate the original layout as closely as possible.  If you have Georgian style windows with individual small glaze pains then we have two viable options for you to replicate this popular look.  Bars placed inside the glass unit leave the windows easy to clean, but maintain the right appearance but for a really authentic look we can offer traditions shaped bars fixed to the surface of the glass both inside and out which really give the impression of separate units.
