Aluminium Windows Prices & Buying Guide

If you're researching the price of aluminium windows, our buying guide will tell you what you need to consider and how to choose if aluminium windows are right for you.

If you're thinking about installing aluminium windows, you might be wondering how much they cost. While some companies sell windows pre-made with a supply-only price, at Everest all our aluminium windows are made-to-measure, especially for our customers' unique specifications.

There are many factors and variables that contribute to the cost of aluminium windows that means every project can be vastly different from the next. We offer a wide variety of aluminium frame RAL colours along with multiple glazing to design your perfect window.

Because of the bespoke nature of our service, we're unable to provide a simple list of prices that covers all these options. Aside from the frames themselves, every installation is different and that also impacts the final cost of installing aluminium windows.

To help you budget, we've created this guide that covers all the factors that impact the price of aluminium windows.

Why choose aluminium windows?

Aluminium window frames have become increasingly popular with homeowners in the UK who are looking for contemporary window styling from a window that has an ultra-slim profile frame.

Aluminium windows are also a choice to replace heritage steel-framed windows to retain the architectural styling mostly seen in Art Deco or modernist homes.

Aluminium has many advantages and benefits as a window frame:

Strength and durability

Aluminium is one of the strongest window frame materials available which allows it to support large frames and large areas of glass. This maximises the glass area while maintaining excellent structural integrity allowing plenty of light to flood in through a window.

The structural integrity of aluminium also means these windows maintain their shape and operation smoothly throughout their lifetime.

Aluminium windows are built to last, with a lifespan that typically exceeds 40 years. The material won't rust, rot, or deteriorate over time, making it one of the most durable window frame options available.

Slimeline contemporary styling

Aluminium’s strength allows for sleek, modern profiles with slim sightlines that maximise natural light and views. This styling is perfect for both contemporary properties and heritage properties that had original steel-framed windows.

The frames can be matched to any RAL colour and have the option for a dual colour finish inside and outside to match your exterior and interior.

Minimal maintenance

Unlike timber, aluminium windows require very little upkeep to maintain their performance and appearance.

The powder-coated finish won't peel or flake, eliminating the need for painting or varnishing. A simple clean with soap and water is all that's needed to keep them looking their best.

Although uPVC is also minimal maintenance, it doesn’t have the same durability and resistance that aluminium does.

Weatherproof

Aluminium windows excel in weather conditions. They won't swell or warp in wet weather, and the powder-coated finish remains stable even in intense sunlight. This makes them particularly suitable for inclement British weather conditions.

However, for coastal locations where windows face increased exposure to corrosive salt water, aluminium frames need a marine-guaranteed finish, which only specialist suppliers can provide. Everest don't guarantee their aluminium frames within 5 miles of a coastal area.

Environmental impact

Aluminium stands out as a sustainable window frame material. It's 100% recyclable and its exceptional longevity means fewer replacements and less waste over time.

Improved thermal efficiency

Older aluminium frames have less than adequate energy efficiency as they conduct the cold (and heat) through the metal frame.

New aluminium windows from Everest feature an advanced thermal break within the window frame and warm spacer bars that reduce the conduction of hot/cold and improve their performance.

The Everest thermal break is a single compound profile constructed from two aluminium extrusions and two polyamide extrusions jointed together.

These innovative systems have improved the energy efficiency of aluminium frames to help reduce your heating bills and maintain comfortable room temperatures throughout the year.

Added value

Perhaps most importantly, aluminium windows can be seen as an investment that can contribute to enhancing the value of your property giving kerb appeal.

Aluminium frames are desirable for all the reasons above, including their aesthetic, durability and longevity.

The combination of reduced energy bills and lower maintenance costs makes them a sound financial investment. Their long-term durability and contemporary appearance continue to add value throughout their lifetime, making them an excellent choice for homeowners.

At Everest, our aluminium windows are engineered to provide all these benefits while meeting the highest standards of quality and performance. Every window is made-to-measure and installed by our expert team to ensure you get the maximum advantage from your investment.

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.

How long do aluminium windows last?

Aluminium windows can last over 40 years when properly maintained. Their durability significantly exceeds that of uPVC windows, which typically last 20-25 years. Everest aluminium windows are backed by our comprehensive guarantee, ensuring peace of mind for years to come.

How energy efficient are aluminium windows?

Contemporary aluminium windows feature advanced thermal break technology, achieving good energy efficiency ratings compared to older aluminium frames.

Everest aluminium windows achieve U-values of 1.4 W/m²K and can effectively keep heat in during winter and out during summer, helping to reduce energy bills.

Does double glazing increase the property value?

House buyers in the UK rate double glazing and central heating at the top of their list when looking for a new home.

Double glazing can increase the property value by up to 10% if the windows are of good quality and the style and colour are in keeping with the property. Therefore, an investment in new windows can pay back if you are thinking of selling.

Beware though, the windows must suit the property and if you get this wrong you can decrease instead of increasing the value. For example, period properties suit timber frames and traditional sash windows. If you remove old sash windows to replace with uPVC double glazing you can devalue the house.
