Benefits of aluminium doors
Aluminium doors are a versatile, stylish solution to your home - and they boast a range of benefits. The benefits of aluminium doors include:

Stylish and versatile
A matte or glossy aluminium finish, in any colour you desire, can transform the entrance to your home. Because of the number of configurations - for example, customising your window panes to choosing the type of handle you want - you can have the perfect door made to your specifications.

Thermal efficiency
A well-made aluminium door with thermo-efficient glass panels give them an energy efficiency of A+ - meaning they’re incredibly efficient at locking in heat in the winter and trapping that cool air in the summer.

Bolstered security
Aluminium doors combine high-strength, durability with modern locking mechanisms and theft protection. This makes them one of the most secure types of doors available on the market.

Ease of maintenance
Because aluminium is treated, it resists the elements and requires little to no maintenance. Its weather-resistant properties coupled with a high strength-to-weight ratio means that a high-quality aluminium door can last for decades and doesn’t warp and corrode over time.

They’re environmentally friendly
For homeowners moving towards sustainability and looking to decrease their personal impact on the environment, aluminium doors can and often are made from recycled aluminium. Not only do they look good, but they keep U-values low, meaning they retain heat well and reduce a home’s reliance on energy to keep it warm.

Unobstructed Views
Aluminium frames facilitate larger, more unobstructed views compared to other materials. Many prefer the sleek appearance of aluminium frames, giving a modern touch to your spare.

Frequently Asked Questions
Aluminium doors offer all the possible benefits you could want in a door with minimal downside. They are strong and durable, resist the elements, can be fitted with a multitude of security options and are one of the cheapest door options on the market - outpricing UPVC doors and timber alternatives. When it comes to the environment, they’re one of the best green solutions available to buy. Not only can aluminium be recycled endlessly, but its thermal-efficiency rating helps homeowners slash the cost of their bills by locking in precious warmth into the home.
Aluminium and timber doors share many of the same properties - ultimately, a well-crafted aluminium and timber door will be indistinguishable from each other in terms of functionality and visual appeal. However, aluminium doors are significantly cheaper than their timber counterparts. In terms of design, the choice is yours. Modern homes may benefit more from a complimentary aluminium door, whereas older, more rustic home designs may better suit a timber alternative.
Despite being a proven winner as a suitable material for manufacturing modern doors, it comes with potential downsides. Some of the disadvantages of aluminium doors include: (1) Oxidation - If aluminium gets scratched or damaged, the material behind the aluminium oxide protective coating can be exposed to the air, causing oxidation. This causes a white power to form on the surface around the scratch which can ruin the look of the door if they are not promptly repaired. (2) Marks and staining - Water that settles on aluminium doors can leave behind water marks and dirt patches. Aluminium doors look great but need regular cleaning to keep them looking their best - which can be a tedious task. (3) It can corrode - Despite the aluminium oxide coating preventing corrosion, in extremely rare cases, this coating can become unstable. Liquids with an acidic PH balance of above 8.5 or an alkaline balance below 4.5 can disrupt the coating making it unable to protect the metal from corrosion. However, this can be easily avoided with proper maintenance. (4) Condensation issues - During the autumn and winter months, it’s not uncommon for aluminium doors and windows to build up condensation on them due to rapid temperature changes and fluctuations in moisture levels. Condensation marks can be simply wiped away with a soft cloth, but this can be tedious for homeowners to keep on top of.
Although they share many of the same benefits - for example, high tensile strength, ease of maintenance and relatively cheap installation costs - aluminium outclasses UPVC when it comes to durability. The aluminium oxide coating used to treat the metal protects it from the elements. UPVC can begin to warp and bend in extreme high or low temperatures, whereas aluminium holds it’s shape no matter what the temperature outside.
Aluminium doors are extremely efficient. A well-made aluminium door with double-glazing has a U-value of 0.9. In simple terms, this means they receive an A+ rating for thermal and energy efficiency - helping to keep your home warm and minimise energy use and reliance during the winter months.
Although aluminium is incredibly hard to scratch with it’s durable, protective oxide coating, it can happen. If an aluminium door scratches, it’s important to treat the area to prevent the powdering commonly associated with oxidation.
Typically, the lifespan of an aluminium door varies anywhere between 50-60 years - but it can last much longer with professional installation, proper aftercare and regular maintenance.
One of the main symptoms of an old door is serious damage and a draft. Although this may be OK in the heat of summer, it’s going to get very uncomfortable come wintertime. The best time to get your doors fitted is in the run up to the winter months if they’re showing signs of wear-and-tear. This means you’ll have new energy-efficient doors in time to keep your home warm as the cold sets in.
