Aluminium Windows

smart logo

white aluminium windowsOur range of aluminium windows and doors features products designed by one of the UK's largest aluminium system suppliers, Smart Systems.

Aluminium windows are virtually maintenance free and offer a quality, durable window solution available in many different styles with the latest high security locking systems as standard.

All aluminium profiles are thermally broken with a polyamide break which provides a very efficient barrier against heat loss through the frame.  The strong and durable profile designs are available in fully sculptured ovolo designs on some systems which provide slim sight lines with the option of chamfered and square profiles also available. 


A Rated Aluminium Windows

No need for expensive triple glazing

energy rated A aluminium windowA rated energy certificateOur energy efficient A rated aluminium windows feature slim sight lines, a wide Polyamide thermal break and a 53mm frame depth to produce a window that acheives an A rating using argon filled Planitherm Total+ double glazing.  Many systems require expensive krypton gas filled triple glazing to acheive an A rating so our aluminium windows are not only energy efficient they are also very cost effective.

Windows profiles are available in flat, chamfered or ovolo profiles and can be supplied externally or internally beaded.  High security shoot bolt locking is standard to all opening side hung or top hung sashes.


Exclusive Features

Our A rated aluminium windows feature two exclusive and unique options designed to improve the aesthetics of the product whilst also improving on traditional installation methods.

Slim Frame Extender 

flush sash and frameOur exclusive slim frame extender increases the depth of the standard 53mm outer frame to 70mm and offers the option of using either the ovolo sash profile to produce a flush sash and frame as shown here or a flat sash profile to produce a recessed style.  The frame extender can also be specified on the bottom of the window to provide a 9mm drainage cill which is especially useful when windows are being fitted above stone cills.
