The Ultimate Guide to Designing with Aluminium

Aluminium is considered the go-to choice for architectural construction and it’s regularly used to design window frames and doors in new properties and commercial buildings. 

Let’s take a look at why it’s so popular.

As it’s such a durable material, aluminium has been used in architectural construction all over the world for many years. It first  appeared in homes in the early 80s, as an alternative to uPVC. 

The stability of this material makes it the perfect choice for architects and those working in the construction industry. In fact, it’s the second most used metal in construction after steel, and is used in a range of applications. 

Aluminium hasn’t always been the go-to choice, however. It was more commonly used for decorative detailing and Art Deco architecture because of its aesthetic appeal.

In the mid-1900s, the Empire State Building was completed, utilising architectural aluminium for most of its interior structure and distinctive look. 

Following this, the popularity of aluminium grew and, with the construction industry discovering more about its durability and stability over other materials, aluminium began being used for roofing, windows, doors, and more.

What are the main advantages of using aluminium in construction?

How do you know if your windows are good quality?

Materials of low quality can develop breaks and cracks, which are dangerous for an architectural design, and as a result, they have a short life expectancy.

High-quality materials require low maintenance, allowing the building to always appear beautiful. Also, selecting quality construction supplies enables you to cut costs in the long run.

It’s essential to consider that sourcing for the most cost-friendly products is not always advisable. More affordable products could require regular maintenance resulting in more future costs compared to the more expensive products.

What to consider when installing aluminium doors and windows

There are many manufacturers of aluminium windows and doors in the market, which can make it hard to decide which brand to trust. 

So here are 6 factors to consider when choosing the right aluminium windows and doors that best suit your needs.

1. Maintenance and operability

How much maintenance is required for the type of doors and windows, and what is the cost? Are your clients aware of this and do they agree to the maintenance that your choice entails? 

2. Illumination

How much illumination is required from windows? Where is illumination essential, can you integrate skylights, roof windows, and space frames to further address the issue? What type of doors and windows will provide the most light?

3.Room use

To ascertain the best choice of door and window, what is the room where they are to be installed used for? What type of door is best as an entrance? Does the room require maximised illumination or reduced sunlight rays? Is sound reduction necessary?

4.Efficiency and sustainability

Aluminium and steel frames are easily recyclable, nearly 75% of all aluminium ever produced is still in use today. With its lightweight strength and unmatched corrosion resistance and durability, aluminium is widely used to build renewable energy platforms like solar panels and wind turbines.

5. Renovation vs. replacement 

Replacement windows and doors may provide a significantly better ROI: if more than 20% of a building’s windows require restoration, replacement may be the less expensive option, because the cost of new windows is often less than restoring them. In addition, the end product is usually superior.

6. Security and safety

Since windows and doors make inhabitants more vulnerable to outside elements, perimeter security and occupant safety are critical factors in choosing windows and doors.

Finally, all these key elements offer critical value to the overall design, functionality, and choice.

Heat loss can be cut up to 75% with energy- efficient windows and doors.

Working out how sustainable a building is relies on a number of factors, but one of the most important indicators is how energy efficient the property is. 

There are lots of elements that contribute to this and play a part in how much heat a property loses or retains. 

However, it’s estimated that a typical house loses 10% of its heat through the windows and doors. (GreenSpec 2022), around two thirds of this is due to radiation through the glazing and poor insulation.

This means that energy efficiency now has a stronger influence on which windows and doors builders, architects, and homeowners choose to purchase. 

As the Government has recently introduced rigorous targets for the green building revolution, making sure that all new buildings are constructed to be highly energy efficient, it’s important for builders and architects to choose the most energy-efficient windows and doors. 

Gone are the days when windows and doors were chosen solely based on their style and colour – it’s now important to think about how they insulate a property, and their impact on the environment. 

How do builders know they’re choosing energy-efficient windows and doors?

Installing double or triple glazed aluminum windows and doors is an easy way to make a property more energy-efficient. According to the Energy Savings Trust, heat loss can be cut by up to 75% with energy efficient windows and doors, making aluminium windows and doors a  go-to option within the industry. 

As well as being energy-efficient, aluminium is widely used because of its intrinsic properties of durability and corrosion resistance.

Using aluminium ensures high-quality and provides a robust material that suits existing and future building regulations.

Modern aluminium products:

  • Resist the elements
  • Provide waterproof protection
  • Provide thermal efficiency for years to come without warping, decaying, and rotting.

All our aluminium products have thermal break technology, providing a barrier between the inside and outside frame, keeping heat locked in, whilst also stopping condensation from forming. They also have U-Values as low as 1.19 W/m2K when calculated as a CEN Standard door.

It is important to keep this information in mind to ensure you’re investing in the most thermally efficient products. 

What are the benefits of aluminium?

  • Optimal security guaranteed: aluminium, offers high levels of safety and security from burglaries.
  • Robust: aluminium is known for its robust qualities, allowing it to stand the test of time in all weather.
  • Long-term investment: Aluminium requires less maintenance and repairs, and it could potentially increase the value of a property. 
  • Environmentally friendly: aluminium is 100% recyclable and, depending on the recycling process, it can retain all of its original properties. 
  • Precision-engineered: aluminium achieves its strength from its chemical composition during manufacturing. Once manufactured, it can cater to complex layouts.
  • Thermally efficient: aluminium bi-fold doors are thermally efficient profiles. They resist the elements, are incredibly waterproof and won’t warp, decay or rot over time. 
  • Diverse customisations available: the possibilities are endless! Whether you want different colours, handles, thresholds and more – you can customise aluminium products.
