Aluminium windows and doors

At Green Home Glazing we have architectural, environmental, design and construction expertise and we are here to assist you with choosing the right solution for your home project.

This is why we have prepared this Guide on aluminium windows and doors:

  • to answer your most common questions,
  • to inform you on what adds value and what works best, and
  • help you understand the best options for your budget and requirements.


  • What are the best windows for the money?
  • How long will aluminium windows and doors last?
  • Are aluminium windows more expensive than wood?

Aluminium windows and doors are commonly less expensive to manufacture, when compared to similar timber windows and doors. The aluminium strength, durability, low maintenance and versatility mean they offer excellent value.

If you are looking for a good all arounder then aluminium is the sensible option when it comes to value for money offering excellent performance, contemporary appearance, and competitive pricing.

Aluminium windows and doors have a life expectancy of around 45 years which is much longer when compared to upvc and timber frames and during this time aluminium frames need little or no maintenance.

At Green Home Glazing all our products come with thermally broken frames which means that they not only provide high levels of thermal and acoustic insulation but they also do not expand. As a result they are not affected by damp environments and elevations exposed to sunlight and high temperatures. Aluminium frames can come with an anti-corrosion protective layer for seaside and coastal locations.


  • Do black aluminium windows fade?
  • Which is better upvc or aluminium sliding doors?
  • What opening types are available for aluminium framed windows and doors?

Aluminium framed doors and windows have greatly evolved from the 70s and 80s.

Since then aluminium frames have become much slimmer, super-slim even, with large glazed panels, power assisted mechanisms, in a trendy, architect-friendly, charcoal coloured appearance, and very wide uninterrupted openings.

And no, that architect-loved Anthracite Grey (aka RAL 7016) will not fade anytime soon but, like any other powder coated aluminium window, it might need a good clean from time to time. Discolouration guarantees have typical lengths between 10-25 years.

Aluminium frames have a level of thermal performance that upvc frames can not possibly achieve.

Upvc and timber frames can expand and contract when the ambient temperature changes while aluminium remains highly stable which allows double and triple glazing combinations.

Aluminium framed windows come in the following types:

Casement windows – Probably the most common type, they open inwards or outwards, with opening hinges to the side, to the top or the bottom of the window frame.

Sash windows – This is a streamlined modern interpretation of the old Georgian favourite.

Sliding windows – Sleek and contemporary and really easy to use; great at opening up your kitchen area to the garden outside on a nice sunny day.

Fixed panoramic windows – Floor to ceiling, from side to side, by the seating area, next to your double end bath or opposite the door into the room offering long uninterrupted views outside.

Tilt and turn windows – Inward openings, Continental in style, a combination of two opening mechanisms to give you full control of the ventilation rates into the room.

Bifold windows – Think of sliding windows but you can now have the whole opening wide open to the garden on that nice sunny day.

Aluminium framed doors come in the following types:

French type doors – The popular patio door type with two panels opening, often, outwards in a symmetrical way.

Sliding doors – With slim or super slim frames and with two panels up to 1500mm these doors will slide effortlessly to provide access to your garden.

Sliding folding doors – With frames that a bit thicker compared to sliding doors these doors will give you the maximum access and they will great the largest possible opening to offer a seamless inside-out relationship between the interior and exterior parts of your home.


  • Are aluminium windows cold / hot to touch?
  • What are the benefits of aluminium windows?
  • Are aluminium windows and doors energy efficient?

A key benefit of our aluminium window and door products is that they come with thermal breaks as standard.

This means that the outer and inner parts of the aluminium frame are not touching but they are rather separated by a continuous insulative barrier that prevents heat transfer from the outer part of the frame to the inner part of the frame.

This thermal break keeps the interior space of your window at a more comfortable temperature and means that your aluminium windows will not feel too hot or too cold when you touch them.

The triple glazing option combined with thermal breaks means high heat efficiency and no condensation created in the inner surface of the aluminium frame (no cold bridging).

Additional benefits of aluminium windows and doors include endless design possibilities due to the flexibility of the aluminium as material and its relative economy and strength-to-weight ratio, as well as a long product lifecycle and an appearance that compliments modern homes.


  • Do you need planning permission for new aluminium windows in a conservation area?
  • Do I need Building Regulations approval for new aluminium windows and doors for my home?
  • Do I need Freeholder (Licence to Alter) approval for new aluminium windows and doors for my home?


You do not usually need to apply for planning permission for the insertion of new windows and doors that are of a similar appearance to those used in the construction of the house (note – a new bay window will be treated as an extension and may require permission).

However, occasionally you may need to apply for planning if your Council has made an Article 4 Direction withdrawing permitted development rights. If you live in a listed building, you will need listed building consent for any significant works – internal or external, and this includes the installation of any patio doors.

If your house is in a designated area (conservation area, national park, area of outstanding natural beauty) there may also be additional restrictions in place. In all these cases, you are strongly advised to check with your local planning authority before carrying out any work. Planning Portal.

At Green Home Glazing our director is a Chartered Architect (GOAStudio London residential architecture) with the Royal Institute of British Architects (RIBA) and will advise you about all relevant planning requirements, will liaise with your local planning authority, and will obtain any necessary planning approvals on your behalf.

Building Regulations

The replacement or installation of new patio doors might require Building Regulations approval. Building Regulations relevant matters include the thermal performance of the glazed doors, safety glazing, ventilation, fire safety, and access. Planning Portal.

At Green Home Glazing we work with London Building Control Approved Inspectors to assess all the Building Regulations related issues for your project and offer certification for all door and window replacement and alterations.

Freeholder approval

If you are a leaseholder you may first need to get permission from your landlord or management company in addition to any other planning and Building Regulations approvals necessary.

Please ask your solicitor to review the terms of your lease in regards to how to approach your Freeholder and for advice on how to obtain the Freeholder approval. We will assist you by providing all plans and specifications your Freeholder needs to grant you the approval.


  • Are aluminium windows and doors eco friendly?
  • Is aluminium 100% recyclable?
  • Can aluminium windows be double / triple glazed?

Aluminium is a sustainable product due to mostly its recyclability and relative strength-to-weight ratio that means less mass is needed to create a door or window. It’s 100% recyclable and non-toxic, leaving a minimal ecological footprint. Recycling aluminium itself requires just five per cent of the initial energy consumed to create it.

According to GreenSpec:

  • After iron, aluminium is the second most-used metal in the world.
  • After oxygen and silicon, aluminium is the third most abundant element in the earth’s crust.
  • 90% of all aluminium recovered from demolition/end-of-life is recycled.
  • The recycled content of products varies widely, but the overall world average is something like 30%. This proportion is only conditioned by the availability of scrap aluminium.

The Recycling World Aluminium Organisation notes:

“Today, recycling of post-consumer aluminium products saves over 90 million tonnes of CO2 and over 100,000 GWh of electrical energy, equivalent to the annual power consumption of the Netherlands.”

The frame material is only one component of a door or window and the glazing type plays a significant part in the thermal performance of the product. According to the Energy Saving Trust, nearly a fifth of heat lost from un-insulated homes can be through the windows.

This means that by choosing and installing the right windows and doors you will be reducing the amount of energy you use and the impact on the environment for the life cycle of the window or door product.

Green Home Glazing combines the performance of triple glazing, the longevity and flexibility of aluminium frames, and thermally broken frames to offer you the most sustainable window and door products in the market for your home project.



  • How can I stop noise coming through my house windows?
  • Can new aluminium windows help with noise reduction?
  • Triple glazing or double glazing for soundproofing when it comes to aluminium frames?

In regards to soundproofing and noise reduction Which? Magazine has the answer when it comes down to double glazing v triple glazing:

“Should I buy triple-glazed windows? Triple-glazed windows have a third pane of glass, so they should make your home warmer and more sound-proof than double-glazed windows.”

 Aluminium windows and doors have a high strength-to-weight ratio and as a result they are capable of supporting heavier glass panels when compared to timber and upvc frames.

In fact only our steel framed products have higher strength-to-weight frame ratios; the number, positioning, and the thickness of the glass panels are major factors that determine the acoustic performance of a door or a window.

Our aluminium frame products also come with thermal breaks as standard; the thermal breaks in the frame prevent heat losses between the inside and outside of your home. At the same time they also create a sound transmission “break” which results in a reduction in noise transmission too.

Typically a standard double glazed unit with two 4mm panes of glass and an air cavity will reduce noise by around 25dB.

Our triple glazed aluminium windows can be manufactured with at least one layer of acoustic laminated glass, glass panels of different thicknesses, and the window can be acoustically treated in order to create a noise reduction of around 45dB as the sound waves get absorbed by the glass panels.

Remember that a noise reduction factor of 10dB equates to a 50% reduction in the volume of a noise, which is a substantial reduction that is enough to create a much quieter home environment and make any external noise much less noticeable.



  • Are aluminium doors and windows safe?
  • How do you secure aluminium windows?
  • What is the safest glazing option for aluminium windows and doors?

Alongside using alarm systems and sensors, it is important that your doors and windows themselves offer a high level of security.

Steel is an inherently strong material, three times stronger than aluminium, and it will provide you with the highest level of security. Aluminium is probably the second safest options when it comes down to durability and strength.

In reality both steel and aluminium offer a highly secure option when compared to upvc and timber frames due to the longevity and low maintenance that is required for both aluminium and steel frames. Timber frames require a certain level of maintenance over time to avoid rot and to retain the strength of the material.

In order to improve security our double and triple glazed doors can come with the following glazing options:

Toughened – to increase strength and safety, it often comes as standard.

Laminated – to provide additional security compared to toughened glass

Obscure – to improve privacy to windows

In addition to the secure triple glazing our steel doors and windows come with robust secure multi-point locking systems, frames assembled with heavy duty hinges, and finger-safe family-friendly joints for added security and safety.
