Window colours

Our windows can be made for you in a great variety of colours.

All our colours are guaranteed for 10 years for colour stability and discolouration.

Most colours are available as full (both sides) or half (colour outside and plain flat white inside).

To preview the texture and colour, please click the frame colour button and then the zoom icon on the colour images.

Disclaimer: We cannot guarantee to match existing colours. For a colour match, please email us with your address for a free swatch.

Internal magnetic blinds

These integrated Venetian blinds are permanently sealed inside the cavity of double-glazed units, keeping them totally out of harm's way in between the glass panes.

How to add blinds
Use the "Internal blind" button at the very left to choose colours; this will enable blinds on all glass panes that are suitable. To enable/disable blinds on individual panes just click on the glass icon on each pane.

    Benefits include:
  • Closed-loop belt transmission system allows smooth and long-lasting function of the blind.
  • The external magnetic slider is treated with a patented anti-bacterial finish, for long-lasting protection also against viruses.
  • No cords, fully compliant with child safety standards.
  • Requires only one control to both raise and tilt the slats.
  • The slats are always clean!

Handle colours

All our handles have secure key locking. 1 handle per opener.

To add openers to your window use the blue icon on each pane.

Handles are supplied in white, chrome, brass/gold, satin silver and black. Traditional cast iron style antique black Monkey tail and Tear drop are also available.

Our window handles

External cill

Most windows require an external cill to drain water away correctly. If you already have a stone or tiled cill as part of the building you may not require a cill.

As standard our cills are 100mm wider than the window frame, projecting 50mm on each side.

95mm stub cill
Our shortest cill, protrudes by 25mm.

150mm normal cill
Our most common cill, recommended for most situations.

180mm long cill
For windows that are set further back into the brickwork.

Please note: The cill height is 30mm and if a cill is chosen then these 30mm will be included within the overall height of the window.
For more advice please contact us.

Child restrictor

This essential child safety device is designed to limit the opening to approximately 100mm (4 inches). It can be released to facilitate full opening of the window.

We recommend that these are used for openers larger than 550mm.

Please note: child restrictors will be sent separately.

Fixing kit

Contains approximately 40 assorted packers of various thicknesses (1 to 4mm) ideal for aligning and fitting the frame and glass units (toe and heeling).

Also approximately 12 concrete countersunk screws 7.5 x 120mm.
Ideal for fixing into concrete, brick, stone, concrete block and wood.

These screws do not require wall plugs. How to video on Youtube.

Opener locks

Every opener on our windows has a locking mechanism with a handle that locks with a key.
We can supply either:

Basic lock
Espagnolette multipoint lock.

Yale Shootbolt lock
Free upgrade!
Perfect for enhanced security. High quality locks supplied by Yale, offer exceptional security advantages. In order to minimize the possibility of the window being forced open they are fitted with additional locking bolts. Recommended.

Glazing choices

We offer many different high quality Pilkington glass choices.

Advanced double glazing Argon filled with 1.22 glass u-rating.

double glazing A+ rated
Superior Triple glazing for an amazing 0.70 glass u-rating.
triple glazing A++ rated
Acoustic glazing for significantly better noise insulation.
More information

Acoustic glazing

Pilkington Optiphon™ high quality acoustic laminated glass offers excellent noise reduction without reducing light transmittance and impact performance.

Ideal for significantly reducing noise from road, rail or air traffic, factories or nightclubs.

Noise is reflected back towards the source and also absorbed within the glass.

The glass unit is made of a 6.8mm acoustic laminated outer pane, a 18mm Superspacer void and a 4mm inner KS pane.

Being laminated it is also very secure and difficult to break into.

The u-value is 1.2, the same as our superb A+ rated double glazing.

Sound reduction Rw(C;Ctr) 41dB(-2; -6)

Frame extenders

A frame extender allows to increase the thickness of the window at a specified side. Great for properties with deep plaster, render or tiles over tiles. 25mm or 40mm extensions available.

Some fitters buy extenders as a precaution, for example where the window opening has not been built yet. Extenders can be modified to accomodate inconsistent side walls.

Extenders simply clip or slide on the window profile as you can see the picture.

Important: The thickness of any chosen extenders is included in the chosen window width/height.

If you wish to add an extender without automatically decreasing your window's width or height please add a note at checkout.

Glass decoration

For added decoration or for a traditional feel we have Georgian bars, Square lead or Diamond lead.

Georgian bars Our Georgian bars are 18mm thick and are placed between the glass panes for ease of cleaning. We do not offer external Astragal bars due to unreliability as they are just taped on. We can instead supply a single horizontal or vertical extra bar. More information on the the glass menu pop-up.

Square lead Our Square lead is traditional lead which is 9mm thick and is placed on both sides of the external pane of glass.

Diamond lead Our Diamond lead is real 9mm thick lead on both sides of the external glass pane.

Note: lead layouts are just a representation, the actual layout will be according to best practice.

Note: For custom or special Georgian/lead layouts, or to match a window with an adjacent door or window, please leave specific instructions as a note at checkout.

Georgian bars

Our Georgian bars are 18mm thick and are fitted between the glass panes for easier cleaning. All Georgian bars are colour matched to your window colours to ensure the right look.

Georgian bars example


Please choose your own number of horizontal and vertical Georgian squares, or leave it on automatic where the actual layout will be set by us according to best practice.

Small adjustments to align the bars between panes will be done by us.

For custom/special layouts please leave a note at checkout.

Special Georgians

These are some of the special layouts available:

Offset three light


Georgian variant

Astragal bars

Astragal bars are fitted externally on both sides on the glass surface and inside to give the complete appearance of separate sections. Whereas Georgian bars are fitted only internally between the glass panes. Astragals imitate wooden traditional glazing bars of old that used to separate windows into smaller sections for an authentic period window look.

Astragal and Georgian bars do not compromise the insulating abilities of the glazing unit as in both cases it remains 1 glazing unit. Our Astragal bars are 20mm thick, and are colour matched to your window colours to ensure the right look.

Astragal bars example

Small adjustments to align the bars between panes will be done by us.

Glass safety

We supply 3 strengths of glass:

Standard: Normal glass, which is dangerous when broken as it breaks in large sharp pieces.

Toughened: Specially treated to increase its strength and safety.
If broken, toughened glass breaks into many small pieces therefore it's less likely to cause injury.

Laminated: Our strongest glass, similar to a car's windscreen, has a laminated layer that keeps the glass together when broken, making it very difficult to break into. Outer side 6.8mm laminated, inner 4mm toughened.
Not with triple or acoustic glazing.

Windows near floors & doors require Toughened glass, Building Regulations.

Opener choice

Top Opener
A top hinged opener with the handle at the bottom that opens outwards.
Top openers cannot have a fire escape hinge.

Left Opener
A left opener (as seen from the outside always) with the hinge on the left side and the handle on the right side.

Right Opener
A right opener with hinge on the right and the handle on the left.

Left/Right openers are usually used in panes that are taller than they are wider. A fire escape/easy clean hinge can be selected for an easier escape route and should be used in habitable rooms.

Dummy Opener
Looks just like a real opener, but it has no handle and does not actually open. It is just decorative to match real operners.

Building Regulations apply to ventilation.

Hinge type

Standard: Our standard hinges do not open fully and are good for rooms on the ground floor that do not require a means of escape.

Fire escape/easy clean
Opens to almost 90 degrees which allows for an easier escape route.
To facilitate easy cleaning of the outer glass surface the opener can slide to the centre, as you can see on the video clip. We recommend openers with this hinge to be at least 600mm wide to provide enough space to escape through.

Habitable rooms require fire escapes, Building regs.

Trickle vent

New Building Regulations

We usually supply Glazpart Link-vents rated at 2500, 4000 and 5000mm² EA (Equivalent Area) to help with compliance with the new Part F regulations. Depending on stock levels we may supply an alternative vent.

Vents are placed at the top of an opener to allow limited airflow without having to open the window. They help to control outside air flow reducing condensation and mould.
The external hood has an insect grill, and the internal vent opens and closes.

Trickle vents will closely (but not totally) match the window colour.

Building Regulations apply to ventilation.

Extra bars

On most panes you can add an extra horizontal (transom) bar, or a vertical (mullion) bar, positioned in the exact centre of the pane. (For other positions please leave a note at checkout.)

These bars are commonly known as "dummy" transoms or mullions although they are real, separating the glass unit into 2 glass units.

To be used mainly with openers.

We do not provide "horns" at the bottom of openers.

Horizontal bars on opener & side
