The disadvantages of aluminium windows
As windows are an investment, you should fully research and be informed before you make a choice about your home improvements. It’s important to also understand the potential drawbacks so you can decide if they are the right choice for you.
Initial investment
Aluminium windows typically cost around 25% more than uPVC alternatives. While this higher initial investment is offset by their longevity and minimal maintenance requirements, it's an important factor to consider when budgeting for your home improvement project.
Thermal conductivity
While contemporary and quality aluminium windows feature advanced thermal break technology, the material itself is naturally more thermally conductive than uPVC or timber. At this time, you cannot achieve the same exceptional level of energy efficiency of a triple glazed uPVC window or a superior uPVC double glazed window. However, Everest aluminium windows still offer good energy efficiency ratings.
Traditional aesthetics
Whilst aluminium windows are perfect for contemporary properties, and some heritage properties such as Art Deco and modernist homes, the frames might not be best suited for homes that look best with timber frames.
Also, some homes in conservation areas or listed buildings will have restrictions on the type of frame material you can install - always check before you consider ordering new windows.
Think about the style of your home when buying window frames to ensure your property maintains architectural integrity and looks its best.
Despite these considerations, the advantages of aluminium windows generally outweigh the drawbacks for most homeowners. The combination of durability, minimal maintenance, and excellent performance makes them a sound long-term investment in your property.
Aluminium vs uPVC windows
When choosing new windows for your home, aluminium and uPVC are two of the most popular frame materials. Each has its own unique characteristics that make it suitable for different requirements and preferences.
Aluminium windows typically last over 40 years, whilst uPVC windows have an average lifespan of 20-25 years. The exceptional durability of aluminium means it won't warp, flex, or deteriorate over time, whereas uPVC can become discoloured and may warp in extreme temperatures.
The strength of aluminium allows for slimmer frame profiles, which means larger glass areas, more light and better views from your home. uPVC frames are a more pronounced part of the window.
uPVC windows are available in a range of colours and woodgrain effects. Aluminium offers full RAL colour-matching options.
While aluminium windows cost approximately 25% more than uPVC initially, their longer lifespan and minimal maintenance requirements often make them more cost-effective in the long term.
Modern aluminium windows with thermal break technology achieve good energy efficiency ratings, but uPVC can offer the more exceptional levels of energy efficiency if this is important for north-facing cold rooms.
Both materials are relatively low maintenance. Aluminium windows require occasional cleaning with soap and water. The powder-coated finish won't peel or fade, and the material won't deteriorate even in harsh weather conditions. uPVC windows also need regular cleaning, but the material can become discoloured over time, particularly in direct sunlight.
Aluminium can be recycled indefinitely without losing quality. While uPVC can also be recycled, the process is more limited and the material eventually degrades. Aluminium's longer lifespan also means less frequent replacement and reduced environmental impact over time.
Aluminium windows are particularly well-suited to contemporary homes, architect-designed properties and large window installations.
uPVC windows work well for traditional suburban homes, budget-conscious projects and standard window configurations. uPVC is also a better option for coastal areas, unless you have a marine-guarantee finish for your aluminium frame.
The decision between aluminium and uPVC often comes down to these key factors:
Long-term investment: If you're planning to stay in your property for many years, aluminium's longevity can make it more cost-effective despite the higher initial investment.
Aesthetic preferences: For contemporary designs and slim sightlines, aluminium is often the preferred choice. If you're looking for a more traditional appearance, uPVC might be more suitable.
Budget considerations: While uPVC offers excellent value for money and good performance, aluminium provides premium quality and longevity for those able to invest more initially.
At Everest, we offer both aluminium and uPVC windows, manufactured to the highest standards. Our experts can help you evaluate which material best suits your specific requirements and budget while ensuring excellent performance and longevity regardless of your choice.
What should your aluminium windows quote include?
When researching the cost of aluminium windows and comparing quotes from different companies, always make sure you compare like-for-like.
An initial low price might not be as competitive when it doesn’t include essential elements that ensure a quality installation.
Here's what should be included in your aluminium windows quote:
- A full technical survey of your property
- The sizes, styles and colours of the frames
- The materials to be used
- Type of glass to be used
- The window energy rating for the glass
- Window furniture and handles
- External window sills
- Full installation including all fixings, trims and sealants
- Disposal of your old windows
Most importantly, make sure you get a certificate to say your installer is registered with a competent person scheme, such as FENSA or Certass. This means that you have automatic approval for building regulations.
