Glass rooms, glazed extensions, conservatories & orangeries

Glass Rooms comprise advanced aluminium structures, doors and windows, designed to extend the living space. With options for all-year-round rooms or temporary summer structures, they come in all manner of sizes, designs and colour.

Often referred to as a Wintergarden, Glass Extension, Glass Boxes or Sunroom, Glass Rooms come in aluminium or a combination of timber and aluminium with some systems. They come either fixed to the home and extending the room or as a free-standing structure in the garden. Using thermally insulated aluminium and high specification insulated glass, these modern glass rooms offer all the benefits of an all-year-round room with excellent energy efficiency, acoustics and interior comfort.

Of course, the benefit of glass rooms and glazed extensions is their full integration with virtually any type of bifolding doors, sliding doors and modern aluminium windows. With large span doors, these fully open up the room like a familiar extension, connecting to the garden seamlessly.

For those projects where a fully insulated system is not required, options exist for aluminium and hybrid structures using single glazed products or non-insulated windows, doors and roof materials.

These come designed as a glass canopy to provide overhead protection from the rain and provide shade when fitted with an awning, or as a summer, garden or glass house when fitted with vertical glass panels which can be fully open in good weather or closed off fully/partially for protection from the wind and rain, while at the same time enjoying the outdoors and a fully unobstructed view of your garden.

Design and features of Glass Rooms and Glazed Extensions

With glass being a major material in the design and execution of glass rooms, there are substantial glass options available. Working with a professional designer of these products, options include sound and sun protection, enhanced security and shading. Designs also include self-cleaning glass, solar glass and a combination of glass and architectural panels.

Additionally, these glazed extensions come with options for climate control, manual or powered blinds and awnings. The bespoke nature of these quality glass structures provides design and product solutions for virtually any project requirement.

Light and a feeling of space mean using slimline aluminium profiles combined with contemporary doors and windows. Most systems offer their own collection of windows and doors. Every one of these is designed for standard designs, open corners, slide and turn systems, low thresholds and other essential design features.

With properties and gardens varying in size, aluminium glass rooms and glazed extensions come fully bespoke. From a basic glass canopy up to a substantial glass structure, the design of these products means any property size benefits from the added space provided by glass rooms and glazed extensions.

Importantly, the design of these structures comes with high specifications and certification for product quality, conformity, security and weather performance.

Conservatories and Orangeries

While traditional bolt-on conservatories remain available, tastes now particularly lean towards more modern and better-insulated structures.

In the same way as glass rooms, conservatories and orangeries consist of primarity glass. Therefore, they have the same temperature fluctuations as any glass structure, such as being colder in the winter and warmer in the summer. In spite of this, Orangeries come with more solid walls and structural elements and offer better interior comfort and heat retention than a conservatory.

The trend for PVCu Edwardian, Victorian and similar styles is less popular than previous years. However, many conservatory specialists now provide all manner of styles and designs, meeting customer requirements and budgets. Overall, the trends and homeowner requirements today remains one for an all-year-round-room wherever possible.

I contacted Nick @ ATS for guidance on what aluminium sliding door systems would be suitable for an opening in an extension that is going to be both wide and tall. He came back really quickly with very detailed and incredibly helpful advice. He is clearly extremely knowledgeable about the systems on the market and their respective features and capabilities. If you’re feeling a bit lost by the overwhelming range of choices out there, I’d definitely recommend contacting him.

After a lot of research to find doors that would meet our unusual size requirements and feeling increasingly uncertain about the best way to spend our small budget, I stumbled on the ATS website, and I'm so glad I did! I contacted ATS to request advice and Nick promptly replied with a wealth of information, providing us with options and relevant contact details. I only wish I'd found them sooner!

I've been so confused about how to achieve the look I'm after, and going round in circles with various window/door companies, trying to get away from the huge chunks of plastic currently around my windows. I didn't expect an email to a company found through a Google search to really help - but I was desperate, so I tried. I'm SO glad I did. Finally I have clear explanations from ATS of where I've been going wrong, exactly what I'm looking for, and a list of local companies that might be able to provide it! The response has excelled my expectations and I feel as if I'm finally inching closer to a home with which I'll be happy and comfortable: thank you.

It is rare that I write reviews, however after my very positive communication with Nick - enquiring about suitable slim sash aluminium windows for my project, I felt that a review was definitely warranted. I can reinforce the many positive reviews posted so far, Nick was very quick to respond, providing comprehensive detail, with excellent independent advice.In summary, great service, thank you Nick.

I dropped Nick at Aluminium Trade Supply an email re high security slim sightline bi-folds and their alternatives and he responded that quickly (and so comprehensively) that I felt bad I’d not paid him for his time!Nick Sir your product knowledge is outstanding and you are providing a level of service that goes wayyyy above and beyond expectations. I’ll definitely make sure I mention Aluminium Trade Supply to anyone I encounter looking for a fenestration solution 🙏🏼

We are looking to replace some old UPVC patios doors with aluminium ones. The ATS website is a great source of advice in an area where clear information is sorely lacking. Having used the website, I then followed this up with a number of specific questions relating to our search, and Nick came back very quickly with clear, detailed and very useful advice.I have been very impressed with both the website and with Nick's advice. My only regret is that I didn't come across ATS before replacing various windows in 2021 - I'm sure it would have saved me a lot of grief and money! Thanks again Nick.

My experience with this firm was exceptionally good and this is notalways the case as a female, dipping a toe into technical waters.I was spoken too with courtesy and at a level that helped me consolidate what was needed .On top of that I was given a list of companies and places where I could obtain the type of product I needed.I could not thank them enough and would certainly go there again and reccommend others do too.
