Aluminium has been called a ‘magical metal’. Mainly found as Bauxite ore, it’s the third most common element in the earth’s crust and the most abundant metal on the planet. But what makes it perfect for use in windows, doors and curtain walling?
Well, it’s the chemical, physical and mechanical properties of modern-day aluminium alloys that account for the steep rise in its global use at over 5% every year. Here are just 8 reasons why the market for aluminium frames in the glazing world continues to grow, now dominating the commercial market and giving PVC-U a run for its money in the residential sector.
Light weight – Aluminium is a very light metal with a specific weight of just 2.7 g/cm3, which is about a third that of steel or copper. In fact, it’s one of the lightest commercially available metals. This makes it ideal for window and door frames, but using a lightweight frame is especially important when it comes to curtain walling. Curtain walls are not structural and are only able to carry their own weight, so the lighter the better.
Resistant to corrosion – if you’re looking for a low maintenance window, then aluminium is your answer. That’s because when aluminium comes into contact with air, a protective layer of aluminium oxide immediately forms on the surface. This layer is extremely resistant to corrosion from anything the weather can throw at it, including acid rain, and won’t be damaged by cleaning products. And unlike timber or PVC-U frames, aluminium window frames won’t swell, crack, split or warp over the years whatever the weather. Protection from corrosion can be increased even further by anodising or painting (usually by powder coating) the surface.
Won’t break – aluminium is both malleable and ductile – in case you’ve forgotten your GCSE chemistry, that means it can be bent or pressed into shape or drawn out into a thin wire without losing its toughness and without breaking or cracking. In other words, its pliable not brittle. In fact, aluminium is the second most malleable metal and the sixth most ductile. This is fantastic news for anyone wanting a curved curtain wall or window, as the aluminium frame profiles can easily be bent or pressed into the required shape without any danger of them breaking.
100% Recyclable – Aluminium is unique when it comes to recycling metals. It is 100% recyclable and the quality of recycled aluminium is identical to that of virgin aluminium. Which means it can be recycled again and again. In fact, nearly 75 percent of all aluminium ever produced is still in use today. This is good news for aluminium supply, especially when you consider that since the first industrial quantities of aluminium were produced around 100 years ago, worldwide demand for aluminium has grown to around 29 million tons per year. But it’s even better news for the environment, because whilst it takes 14,000 kWh to produce 1 tonne of new aluminium, it only takes 5-10% of this to remelt and recycle the same amount. Which means a smaller carbon footprint and lower costs.
Very strong – aluminium alloys are used to make window door and curtain wall frames. That’s because pure aluminium on its own doesn’t have a high tensile strength. However, once it is alloyed with other elements like manganese, silicon, copper and magnesium its strength increases vastly. The tensile strength of pure aluminium is around 90 MPa but can be increased to over 690 MPa as an alloy. In fact, Aluminium which as we’ve already seen is one of the lightest engineering metals, has a far better strength to weight ratio than steel when used as an alloy. Even more impressive, unlike steel, the strength of aluminium increases the colder it gets, whereas steel becomes brittle at low temperatures (below 0oC). This means that aluminium windows, doors and curtain walling can more than cope with the most extreme winter temperatures in the UK. The lowest temperature recorded in the UK was -27.2°C in Scotland.
Readily forms alloys – as we’ve already seen aluminium is usually alloyed with other elements to improve its physical properties. For example, the strength of pure commercial aluminium can be increased by 20% by simply adding manganese. Aluminium also readily forms alloys with silicon, copper, zinc, iron and magnesium. This means it is possible to produce a range of alloys with properties tailored to particular applications. Aluminium glazing firms use alloys of aluminium with silicon and magnesium which are an excellent choice for extruding aluminium profiles. They are very versatile, heat treatable, highly formable, weldable and have high strength plus excellent corrosion resistance.
Easy to make into frames – aluminium window frames are made using an extrusion process i.e. by forcing the pre-heated aluminium alloy through a die to create an aluminium profile. These profiles are then joined together to form the frame. It is the design of these profiles that gives the window frame its unique characteristics. They can be complex designs but thankfully these intricate shapes can be achieved using a single extruded section, so that the profiles are both strong and durable. Aluminium also has good machinability, making it easy to accurately fabricate the aluminium profiles into the finished window frame.
Decorative – aluminium can be easily anodized or powder coated to give it a decorative smooth or textured finish. This means that aluminium windows, doors and curtain walling not only perform well but look fantastic too. Anodising is carried out by immersing the aluminium in an acid electrolyte bath and passing an electric current through it. This converts the metal surface into a decorative, durable, corrosion-resistant, aluminium oxide finish. The aluminium oxide is fully integrated with the underlying aluminium, so that it cannot chip or peel, making it amazingly durable. The aluminium oxide has a porous structure so needs to be sealed to make it resistant to corrosion. The sealant can be clear or contain special dyes so that anodized aluminium is available in a wide range of colours. The alternative is to powder coat the aluminium with paint. The aluminium is pre-treated either by anodizing or via a chemical reaction to form a corrosion resistant barrier, and can then be powder coated in any RAL colour. At Senior Architectural System we have a state-of-the-art powder coating facility at Denaby. The pre-treated aluminium bars are earthed and the paint powder is given an electrostatic charge as it leaves the guns. This helps the powder molecules to stick to the bars via electrostatic charge, just like dust particles stick to your TV due to the electrostatic charge on the screen! The bars are then cured in an oven where the powder melts and forms a uniform, flexible and smooth finish which is resistant to weathering for 25 years.

| Is UPVC Or Aluminium Better For Bi-Folding Doors? |
|

o after months of considering bi-folding doors you have finally come to the decision that bi-folding doors are ideal for your home… now it’s time to make the next decision, do you want uPVC aluminium bi-folding doors or uPVC bi-folding doors? In this article we have put together the pros and cons of aluminium and uPVC bi-folding doors to help you made the choice a little simpler;
Aluminium Wins For Longevity
Most uPVC bi-folding doors will only offer a 10 year guarantee but they can start looking tired before this time because they gain a yellow or pink tinge. Opting for lower quality uPVC bi-folding doors will be cheaper at the time, but over time it will cost you more. The strength of aluminium bi-folding doors is far stronger than uPVC bi-folding doors and aluminium bi-folding doors will not reduce the aesthetical value of your home where uPVC bi-folding doors may.
Aluminium Wins For Maintenance
uPVC bi-folding doors can warp or bend with age, especially as it is outside and exposed to direct sunlight for long periods of time. However, aluminium bi-folding doors offer flex, expansion and contraction in direct sunlight and minimal maintenance is required to keep your aluminium bi-folding doors in good working order.
It’s A Drawer For Aesthetical Value
Aluminium offers a crisp, sharp metallic finish to your bi-folding doors adding lots of aesthetical value to your home, while uPVC bi-folding doors also look great it’s just that they begin to look worse over time while aluminium bi-folding doors will keep the look and feel for years to come. Previously aluminium bi-folding doors were not as popular as they were only available in a typical metallic finish, black or white but they are now available in various colours.
UPVC Wins For Pricing
As discussed previously uPVC bi-folding doors are much cheaper than an aluminium bi-folding door and it is often the hefty price tag of aluminium bi-folding doors that puts many customers off. However, over time aluminium bi-folding doors will be the cheaper option as they are high quality and easy to maintain.

All that makes uPVC windows sound pretty brilliant doesn’t it? Well there are also some unique benefits to aluminium windows that are worth knowing about:
Aluminium tends to be stronger than uPVC. That means that aluminium windows can have a slimmer appearance, and a larger glass surface area due to the strength of the frames. For this reason they’re very popular with commercial and public buildings like schools, offices and government buildings. This can be a good benefit for a residential home too, if you’re looking for a particularly large design.
Powder-coated aluminium is extremely durable, which means whatever finish you choose will last for a very long time. Aluminium windows can last up to 20 years.
Aluminium windows are also environmentally friendly. Aluminium is indefinitely recyclable – when you recycle it, it creates very high quality new aluminium and the process only uses 5% of the energy needed to create the initial metal.
Aluminium has greater design flexibility than uPVC – the range of colours available (including dual colours) is amazing.
Aluminium windows are designed to withstand some pretty extreme conditions, and survive tests in severe exposure categories.

The sleek and slender profiles of aluminium windows offer endless architectural opportunities, particularly when a minimalist or industrial look is desired. Able to mimic the look of steel and achieve excellent thermal performance, aluminium profiles are ideal not only for renovation and restoration projects, but also projects ranging from residences to today’s most ambitious civic projects.
Take a look below at 10 inspirational examples of sleek aluminium solutions, architecturally designed to perfection.
Bloemhof
Architect: Marlies Rohmer
1. Bloemhof
This project is all about contrasts. Containing 56 starter residences and 1450m² of commercial spaces, ornamental brick façades create a timeless effect. But architect Marlies Rohmer specifically did not want to create a historic building. Here, sleek and modern aluminium frames contrast strikingly against the coarser facade elements.
7even Gardens
Architect: Jaspers Eyers Architects
2. 7even Gardens
An urban oasis of residential units, offices and shops located within a former cigar factory, architect Jasper Eyers aimed to protect the original character of the building whilst introducing modern elements. Existing columns and technical features remain to retain the industrial look. To mimic the original look of steel windows, a slender aluminium profile system measuring just 40mm in width was chosen. The system has the added benefit of satisfying modern energy conservation requirements.
Crystal
Architect: Libor Hrdousek & Radek Lampa (Atelier 15)
3. Crystal
In Prague, Crystal takes on a chessboard appearance, unifying the building façades and further creating the effect of a crystal by reflecting and refracting light. A standard aluminium profile system could not be used here so custom elements were made, including corners and channels. The shape of these profiles was prepared using 3D models of the desired forms.
Cartwrigth Gardens
Architects:
Maccreanor Lavington Architects
T.P. Bennett
4. Cartwright Gardens
Elegant aluminium glazing profiles were used in this central London residential block. In addition to extremely slender aluminium profile sections, perforated aluminium screens located to the sides of the windows incorporate an insulated panel that can be opened for ventilation. Mimicking the look and feel of steel, the solution respects the style of more traditional steel-framed windows, while offering a thermally improved solution.
Philips Light Tower
Architect: AWG Architecten
5. Philips Light Tower
A former factory used for manufacturing lightbulbs, the Light Tower has been transformed into a multi-purpose complex. The building was not only restorated, 3 new volumes were added to the existing site. In order to meet requirements of the Listed Buildings Authority, the windows had to be restored to their original state with steel frames. The windows also had to fulfill modern acoustic and thermal standards. As the original steel window frames were unable to meet these requirements, a sleek aluminium profile was chosen. Measuring just 48 mm wide, this profile closely resembles the original. The same profile was used in the three new volumes.
The Brouwhuis
Architect: Bedaux de Brouwer Architecten
6. The Brouwhuis
Located in Tilburg, the Brouwhuis blends into its environment. It is largely open on three sides thanks to the many windows and slim aluminium profiles used. These profiles were coated to create a matte, almost steel-like look. The open nature of these three facades contrasts beautifully against a solid wall of black stained planks.
Buftea Residence
Architect: Razvan Oprescu (LLOX Architecten)
7. Buftea Residence
Inspired by the Mies van der Rohe principle of less is more, this single storey residence in Romania features spectacular floor-to-ceiling glazing and with slender aluminium frames that opens up to the natural surrounding and waterfront. Appearing to almost float, it is a great example of this modern master’s legacy.
Barco One Campus
Architect: Jaspers Eyers Architects
8. Barco One Campus
Over 3,500m² of glass and aluminium were installed here in what is known as a reversed curtain wall façade. Where the structural element of the wall is positioned to the exterior of the building, with only narrow trim caps of the curtain wall visible to the interior. The effect of this solution is incredible transparency and great outward sightlines.
Forest villa Voorschoten
Architect: architect eigen huis
9. Forest Villa Voorschoten
This clean lined house conceals aluminium windows largely behind wood. A curtain wall profile for the large window opening up to the side of the woods, a curtain profile on wood for the light strip in the roof, minimalist sliding windows for the terraces and standard front door windows were all made in one material - aluminium - thus enhancing the minimalism of the project.
Qatar National Convention Centre
Architect: Arata Isozaki
10. Qatar Convention Centre
Creating an incredible sense of spaciousness, an extended curtain wall system here allows for maximum amounts of daylight to illuminate the grand interior. Spanning up to 16m without additional support, the façade with both aluminium and steel components features stainless steel covers on the inside and it is reinforced with façades measuring 650mm in depth and covering 5500m².

US Aluminum is a Fabricator and Supplier of Entrances and Storefronts, Windows and Curtain Walls, Hurricane Resistant Building Fronts, Sun Control Systems, Blast Mitigation Systems, Ribbon Wall, and Custom Extrusions.
History
In 1958, John Linder started a regional aluminum extrusion and architectural products supply company in Southern California under the name of United States Aluminum. The founding of the company came as a progression from Linder's previous venture, Rigid Metals.
During the same time period Cornelius C. Vanderstar started the Louver King Company in 1957 to manufacture aluminum jalousie windows out of an old 2500 square foot garage in the suburbs of Los Angeles. By the end of 1958, the Louver King Company had grown their sales and into a 12,000 square foot building. A sliding window among other products were added to the product offerings in 1959 to diversify the company's position. 1960 saw another move to a larger 20,000 square foot facility. In 1962 the Louver King Company bought an extrusion press to establish a consistent supply chain. In 1964 Cornelius Vanderstar approached John Linder of United States Aluminum to sell some of his excess extrusion capacity, and wound up on the purchasing end as he purchased United States Aluminum Corporation. Linder stayed on with the company as a manager to help Vanderstar learn the intricacies of the business. United States Aluminum continued to grow with Vanderstar's acquisition. In 1977 United States Aluminum bought a Dallas-based storefront and entrance fabricator, Texline Aluminum Products Co. The Dallas manufacturing facility was soon moved just South of Dallas to the town of Waxahachie, Texas. Over time, the Waxahachie complex has grown into United States Aluminum's headquarters, with an International Extrusion plant and RACO Interior Products facility at the same location. Soon after in 1978, they purchased Armesco in Chicago, which gave the company a base to work into the North Eastern United States. In 1985 a new manufacturing facility was opened in Rock Hill, South Carolina to service the South East. 1996 saw the acquisition of Orca Architectural Products in Langley, British Columbia, Canada, setting the stage for United States Aluminum to become an international products supplier.
In July of 2011 C.R. Laurence Co., Inc. (CRL) Announces Acquisition of U.S. Aluminum Company (USAL)
C.R. Laurence Co., Inc. (CRL), a leading global supplier to the glazing, railing, architectural, construction, industrial, and automotive industries, is pleased to announce the acquisition of U.S. Aluminum Company, formerly a part of the International Aluminum Group.
In making the announcement, Lloyd Talbert, President of C.R. Laurence, states, "We are very pleased to announce the acquisition of the assets and business of U.S. Aluminum, one of the most respected names in the storefront and curtain wall business. We are proud of this new association and are especially pleased that Tom Harris, Executive Vice President of the predecessor company, will join us as President of the new company. Tom has over 20 years experience leading major storefront and curtain wall suppliers, and is well respected in the industry. Tom will spend the next few weeks assembling a team to rebuild this iconic brand, and will be integral in the further development of a comprehensive architectural hardware program."
Talbert continues, "Our plan is to contact customers and vendors of U.S. Aluminum, as well as many of their former employees, to re‐establish relationships. We wish to assure those U.S. Aluminum clients who have jobs in progress that we will immediately assess the status of their orders and expedite their completion and delivery. We're confident that we can restore the U.S. Aluminum brand to its former luster. We also appreciate the support and encouragement we have received from many C.R. Laurence customers during this process."

LONDON (Reuters) - Prices of aluminium for U.S. consumers in the transport, construction and packaging industries are sliding because the market is expecting exemptions for producers in the United Arab Emirates and Bahrain.

This thinking follows agreements by the two Arab states to establish formal ties with Israel, which they signed at a ceremony hosted by U.S. President Donald Trump at the White House in September.
U.S. aluminium prices are based on the physical premium AUPc1 now at $263 a tonne from $335 mid-September, plus the benchmark price CMAL3 on the London Metal Exchange at $1,750.

Jorge Vasquez, founder of consultancy Harbor Aluminum, said the UAE exported about 550,000 tonnes of value added primary aluminium to the United States last year and Bahrain exported 150,000 tonnes to the United States.

“The peace agreement gives a reasonable case for the market to consider the possibility of an exemption on aluminum products from the UAE and Bahrain, in which case it would likely be based on hard quotas,” Vasquez said.

U.S. exemptions to the 10% import tariff for primary aluminium or products typically come with informal or formal quotas, imposed last month on Canada, which previously had an exemption.
Hard quotas could mean producers, such as Emirates Global Aluminium (EGA) and Aluminium Bahrain (Alba) ALBH.BH struggle to sell more to the United States than they already do.

“Exemptions could have a larger, longer lasting impact on premiums if the UAE or Bahrain start shipping large amounts of primary aluminium to the U.S.,” an aluminium trader said. “An exemption means more profit for their producers.”

EGA declined to comment on its U.S. exports, but said it sold a total of 2.60 million tonnes of cast metal in 2019, of which 87.4% was value added products.
Alba produced more than 1.36 million tonnes of aluminium last year. “Alba sells mainly billet to the U.S. market. In 2019, 11% of our sales went to the United States,” it said, adding 44% of its sales last year were value added products.
Consultants at CRU estimate global aluminium supplies at 64.1 million tonnes this year, up 1.5% from 2019.
