Thermal Efficiency — One of the benefits of aluminium doors that cannot be overstated is their incredible thermal efficiency. These doors maintain reducing condensation and solar glare. And we can improve the glazing from double to triple. If you’re choosing a solid door with window panels we can offer U-values as low as 0.9 W/m2K, far exceeding government standards of 1.6 W/m2K.

Modern Look — A front door is the face of the home. As such, it deserves consideration. When you choose us for your aluminium door supply, we can ensure that you’re getting stunning chic designs. These doors work well with Scandinavian or Japanese minimalist designs, which is why they’re so popular.

Environmentally Friendly — Unlike many other materials, aluminium is recyclable, losing very little of the material’s properties. That’s one of the reasons that it’s so popular as a construction material. Rising government standards mean that building materials are coming under more scrutiny for sustainability. You’ll want to make the right choice and choose aluminium.

Enhanced Security — Our aluminium doors are tested to PAS24 standards, ensuring that these aluminium doors provide the ultimate security to the homeowner. Additionally, they come with 10 point locking systems. Since we offer Ultion locks as standard along with Yale hardware, including door handles, these are yet another way we ensure great security.

Weatherproof — All of our products are tested to BRFC standards to ensure that your next installation meets environmental standards. Depending on design, we can offer double rebated EPDM centre gaskets for enhanced draught and water protection. Plus, the glass we use is tested to air tightness of Class 4; water tightness to Class 9A; and wind resistance to Class AE2400.

Powder Coating — Whatever colour you choose for your aluminium door, the anodised powder coatings ensure that the door stays colourfast and rust resistant. We occasionally offer a marine grade coating to make sure that these aluminium doors are weatherproof and rust resistant, keeping these doors

Design Choice— At Direct Trade, we offer choices for your next aluminium door. Which is why we have over 20 great designs. If you’re looking for modern designs with slim window panels, we can offer 66mm triple glazed and laminated glass units. For glazed doors we can offer glass thickness up to 32mm, with max dimensions of 1000mmx 2500mm (WxH).

Incredible Manufacturing

At Direct Trade, we fabricate all of the doors that we supply and install. So we know just how solid aluminium doors are. The classic yet modern looks are combined with their incredible versatility. While we have seen them used for external or internal doors, we think they look fantastic with our other steel partitions or steel look internal screens.

Aluminium doors don’t just provide great natural light; they offer equally incredible thermal efficiency. For this reason, our clients never need to worry about these doors. We fabricate aluminium doors using the best of the best: Smart systems. Considering Smart is a leading supplier in the aluminium industry, we know that they offer unparalleled door profiles.

Which is why we can install glass of up to 38mm, depending on the design. Furthermore, you can choose to get a single or double door. But with polyamide thermal breaks, these doors lower the heat transfer out of your home. These doors can offer U-values as low as 1.5 W/m2K. That’s better than many other doors without glazing.

Stylish Designs

Talk to our Slough team about the different style options we have for your next door. If you’re looking for a door to your garden consider our aluminium bifolds and patio doors. We believe in creating elegant designs with slim sightlines so that homeowners can enjoy the views of their garden or cityscape.

While they pair well with our steel partitions and internal screens, we also think they work well with our aluminium windows and flat roofs. When you order with Direct Trade, you can customise your aluminium door for the ultimate security standards.

We offer Ultion locks and Yale hardware. That way, you can be sure that these aluminium doors are both aesthetically pleasing and ultra secure. Look at our various hardware options to see if they match the designs you’re looking for.

We’ve had great success marrying these ultra chic designs to period homes, so we think you’ll be able to create the perfect designs for your next installation.

A Good Lock Is Not Enough

Security is Our Priority

While we can provide 10 point locking systems with our aluminium doors and double doors with dual locking mechanisms, we always use Ultion locks as standard.


The Benefits of Ultion are Numerous

Let’s start with the fact that they have a £2000 anti snap guarantee. If your door is broken into with snapping, they will refund you £2000 and replace your lock.


State of the Art Design

Furthermore, Ultion locks have 11 pins, meaning they are just shy of 300k key combinations, making them virtually impossible to jimmy.


Fantastic Features

With upgrades, you can control your Ultion lock from your phone and unlock your door from the comfort of your car.

    Superb company. Highly recommend them. Proper engineers for design and fitting. We changed spec due to some building changes and they were clear and responsive to queries and redesign. Really trustworthy group of people from sales to design to fitting. I would use them again without hesitation. Warm regards Daniel

    Daniel Champman

    The team delivered great sliding doors at a more competitive price than other suppliers. They responded to our changing development schedule without making it an issue and have provided great aftercare as well.


    We had been severely let down by a previous supplier, but when we turned to Direct Trade Windows for help, we hit the jackpot. Helping us to transform a residential development in Hersham, they supplied us with high-quality, ultra-slim Cortizo sliding doors, complete with the bespoke sliding options that we needed. Our requirements were very specific and not readily available on the market, but Direct Trade Windows really went the extra mile to help us out, coming through with quality products and excellent service. We will definitely be using their services again.

    Nothing but praise for this outfit. It was a pleasure to work with them. It was a nerve-wracking undertaking for us, the biggest single expense to fit three large window/french door combos in our extension, yet the team made it a relatively relaxing experience with their professionalism and good humour. Thank you all so much for everything you and the whole team have done to get from the initial sale (well done Hash!) to the fun visit we made to the workshop, to the design and its multiple iterations (thank you Taz!) and finally to the installation. Thoroughly recommended.
