Aluminium Windows

Slim, modern and thermally efficient.

We supply and install the industry-leading Smart aluminium window system, available as either casement windows, tilt and turn windows or French windows.

With a multitude of products on the market to choose from, we have done the hard work for you. By using Smart products including Heritage 47, we can cover all the bases and offer a product that fit every customers’ requirements. There are further product ranges within Smart, including the Heritage 47 range, which are detailed slightly more below.

We also supply and install a range of Senior Architectural Systems curtain walling, most notably the SCW+ system.

All of the different options are also available to view in person at our showroom to really get a feel for them. In-depth technical information on all of our aluminium windows and doors is available on request. Feel free to get in touch.

Why Aluminium?

Our customers tend to choose aluminium windows for their home for the following reasons.

  • The slim frames of aluminium windows make them a must have when trying to achieve a modern aesthetic.
  • Anyone who has experienced “old” aluminium windows that are not thermally broken can tell of the masses of water gathered on the cold metal on the inside. Modern aluminium windows, with their thermally broken frame and multi-chambered profile, no longer cause condensation problems. This was a huge breakthrough that has made aluminium windows a much more viable option.
  • You can have your aluminium windows powder coated in over 200 RAL colours with the option of having one colour inside and another colour outside. This aspect really appeals to many of our customers, particularly because aluminium is the material of choice in many self-build projects.
  • The longevity of aluminium windows is also a huge factor. Not only is the colour, the metal and the marine-grade powder coating guaranteed for 25 years but the sturdy and robust feel of aluminium appeals to many of our customers.

Smart Windows

Our standard aluminium window for residential properties is Smart’s Alitherm 300 window. With its slim frames, sturdy feel and thermal efficiency, it tends to tick every box of most customers. What’s more, the Alitherm 300 is available in 3 suites. Squared, sculptured and chamfered. Squared giving the ultra contemporary look; sculptured giving the more ornate and decorative look and chamfered offering something in between.

All three suites of the Alitherm 300 are on show at our showroom, so come on down!

Smart Heritage 47 Windows

For the ‘crittall’ or ‘slimline’ look, we supply and install the ever-popular Smart Heritage 47 system.

As a much more cost effective alternative to steel/crittall windows, it has fast become one of our most popular products.

We have the Heritage 47 system on show at our Kent showroom so make an appointment to come along and see it in the flesh.

Come and see for yourself.

The best way to decide which aluminium system is for you is by coming to our showroom where you will be able to see our most popular colours, handles and all the other options for yourself.

When it comes to making such a substantial investment in you home, we think that it is only right that you see all the options and exactly what you’re ordering before you do so.


We’re at Unit 8, Queenborough Business Park, Queenborough, Kent, ME11 5DY.

Don’t compromise on security.

  • Shootbolt locking

As any of our team will be able to show you, our aluminium windows are fitted with multi-point shootbolt locking mechanisms. Really, this means that when you turn that handle to lock the window shut, not only do bolts lock into their keeps next to the handle, but shootbolts at the top and bottom of the window lock into their keeps too.


  • Night-vent facility

There are two positions in which you can close all of our windows. First is the normal fully locked position, which is fully closed. Secondly, you can close the lock the window in its “night-vent” position, which locks it in a just-slightly open position, allowing ventilation into the property without compromising on security by leaving a window wide open inviting potential burglars in. This “night-vent” opening position is obviously not as secure as the fully closed position but it is certainly a good middle-ground that ventilates and secures the property.

With ever rising fuel and energy bills, why would you add to your bill by buying windows that are letting heat and money out of your house unnecessarily?


The energy efficiency of an aluminium window is determined by a few key things.


  • Thermally broken aluminium

Our aluminium windows are now thermally broken. To visualise what this means, if you cut one of our window frames in half so you can the cross section of the inside, you would see that in between the inner and outer “pieces” of aluminium is a black composite non-metallic material. This is called a polyamide thermal break and it has revolutionised aluminium windows. Until its introduction, aluminium windows were solid aluminium all the way through, which meant the cold could travel all the way through it, causing poor thermal values and condensation on the inside. One of our team can give you a demonstration of this feature either at your home or at our showroom.


  • Spacer bars

Spacer bars are the things that separate the two (or three) pieces of glass in a double or triple glazed unit. Up until a few years ago, the industry standard was for this spacer bar to be made out of metal. These metallic spacer bars are still available and are still used by some companies to save money. The problem with these metallic spacer bars is that they allow the cold to shoot straight through the bar and make the glass area on the inner pane around the metallic bar cold, causing the condensation all the way around the edge of the glass, which many people have experienced in the past. However, now we use what’s called ‘warm edge composite spacer bars’, which are made out of a composite material designed not to transfer the cold meaning the glass on the inner pane does not get cold as it does with metallic spacer bars. By only using modern warm edge composite spacer bars, we can ensure that our customers don’t experience condensation on the inside of their windows whilst improving the BFRC energy rating too.


  • Argon-filled

Our glazed units are all argon-filled as opposed to inferior air-filled units. Argon is a noble glass which means it doesn’t react to anything as much as normal air does. This means that heat is not lost as easily through the unit. If you use air-filled glazed units, the heat can escape through the unit much more easily.


  • Multi-chambered aluminium frame

To make it even harder for heat to escape from our customer’s homes, we use multi-chambered profiles in our frames. This means that the inside of the aluminium frame is not only thermally broken, but is also split into different chambers. This of course, improves the thermal efficiency of the window and its energy rating too.

Glass is something that can be skimped on. We don’t.

To go alongside the other energy-efficient features of our aluminium windows, we use Saint Gobain Planitherm Total Plus as standard.  In situations where building control or architects have specified a certain thermal U-value, we use Planitherm One glass to further improve thermal efficiency. These glass designs work to make our customers homes more thermally efficient as follows.

On the inside pane we use the latest magnetron-coated ‘Low-E’ or Low Emissivity glass, which has an invisible coating on it that dramatically reduces heat transfer and also increases heat reflection back into the room. Therefore, glass without a low-e coating will absorb the heat from your home and radiate it out onto the colder outer pane, where it is more easily lost. Low-e glass has a special coating which is a poor radiator of heat and does not allow heat to be transferred to the outside.  Instead, the low-e coating actually reflects the heat back into your room.

On the outer pane, we use an ultra-clear Low Iron Glass, which not only allows as much light in as possible but also brings in the suns rays increasing the windows ‘solar gain’, which means you’re heating up your home with free energy from the sun as opposed to reflecting it back out as you would with other less energy-efficient glass.

The importance of energy efficiency is summed up by the British Fenestration Rating Council’s (BFRC) introduction of the Window Energy Ratings Scheme. With this universal rating scheme, it is now possible to independently measure the efficiency of windows just as you would with cars, fridges or washing machines. This is great news for the consumer who now have a much better idea about the thermal efficiency of the windows they are buying.

The BFRC rate the windows from A+ to G, with A+ being the most energy-efficient and G being the least. Those achieving a C-rating or above demonstrate they have been designed, manufactured and tested to provide a good level of overall thermal efficiency. Thankfully, all window installers must install at least a ‘C’ rated or above window.

We guarantee all of our aluminium windows, and this is insurance-backed.

Not only do we guarantee our products to you, but for added peace of mind, we also pay to have our guarantees insurance-backed, so if anything happened to us as a company, you can rest assured in the knowledge that you still have your full guarantee. The guarantee for our aluminium windows covers the aluminium itself and colour for 25 years and the installation, handles, hinges and the glass unit for 10 years. Everything except accidental damage or misuse is covered.
