The benefits of installing a new aluminium front door

Aluminium is well known for its high strength and versatility. For decades it has been widely used in both commercial and residential applications and is amongst the most popular material choices for the construction of doors and windows. If you still need convincing as to the benefits of an aluminium door, let us debunk some myths for you :

  • Aluminium doors are high maintenance - Aluminium does not corrode, rot, flake, peel or rust. It is weather-proof and is resistant to pests. Aluminium doors are ideal for many different types of homes and businesses in London because they require virtually no maintenance and can be wiped clean with just a damp cloth. Aluminium is also a fantastic choice for doors that are constantly exposed to the elements.
  • They aren’t suitable for traditional houses - Aluminium doors, with their extremely slender frame depth and sleek finish, actually serve as a great choice for traditional houses. They provide a modern touch that pairs well with both hardwood and stone sub-frames.
  • Aluminium doors lack style or class - Gone are the days when aluminium door frames were only available in silver and white. The current generation of aluminium frames on the market are available in charcoal and grey, which have proven to be very popular. With the advanced technologies employed today, you also have the option to have a powder coated, or spray painted aluminium frame to match any colour you desire. You can also choose a glossy or matte finish.
  • Aluminium is not eco-friendly - Aluminium is one of the easiest metals to recycle. If, in the future, you choose to refurbish your London home, aluminium doors can easily be transported to your local recycling facility for reuse.
  • Aluminium performs poorly with temperature changes - Unlike other metals, aluminium is not affected by minor changes in temperatures and hence does not contract or expand with temperature variations. When it comes to aluminium frame fittings, thermal breaks help keep them perfectly moulded to the frame.
  • Aluminium is a poor thermal insulator - Doors fitted with quality aluminium frames feature thermal breaks that create small spaces, preventing heat from escaping. Some aluminium frames even have insulation polyamides installed inside them. So, even though aluminium itself may offer low insulation properties, modern aluminium doors have features that fully mitigate this.

Aluminium doors also make great patio doors that feature luxurious floor-to-ceiling windows. Aluminium patio doors allow lots of natural lighting in, whilst providing an unobstructed view to outdoor living areas. Patio doors are well known for their ability to lighten a room, and aluminium Patio doors provide a clear, open view of your back garden, whilst providing an abundance of natural light to make your interior feel light and expansive!

Aluminium Doors for the Modern Age

Since the early 80's and 90's, aluminium doors have come a very long way. Contemporary, high quality aluminium front doors are now very much in favour once again, and are a favoured choice of architects in London, with aluminium bi-folding doors being a particularly popular option. When you come to choose your next front door, here’s why you should seriously consider installing an aluminium door:

  • With sleek, slim lines in black, white, or a subtle charcoal colour, and in either a matte or gloss finish, a new aluminium front door is sure to give your London home a stylish facelift.
  • Slim sight-lines means that windows mainly consist of glass, allowing more light in and providing clear views.
  • Glass is an excellent insulator, this means that large panels of glass offer enhanced thermal performance. Aluminium doors are constructed with innovative fabrication methods and fitted with new performance-enhancing features. Enhanced glass panels bring increased levels of security and energy efficiency.
  • The slightly higher price of aluminium doors is compensated by the fact that they are practically maintenance-free and do not damage or corrode easily.
