Hybrid Windows and Doors

Hybrid Windows offer an entirely different proposition for glazing in the home.  Hybrid products combine all of the best features of different materials, such as timber, aluminium and even PVCu.  All these different materials come together with the glass, forming one complete product.

These innovative windows and doors offer excellent aesthetics, high performance, outstanding thermal efficiency, and a big range of products for the home.

Information about Hybrid Windows and Doors.

Windows and doors in hybrid materials typically feature a combination of two materials, each one different on the inside and outside of the window.  For instance, there are hybrid products having coloured aluminium on the outside and wood on the inside.  There are also hybrid having PVCu on the outside with wood on the inside.

Importantly, the prominent feature of hybrid materials is the excellent thermal performance with some of the lowest U-Values and best window energy ratings. Sound insulation is also better than single materials too. Another key feature of hybrid materials is the combined strength. As a result, aluminium and timber hybrids offer bigger windows sizes and larger opening elements, compared to single materials.  With hybrid windows and doors, you also get more expansive glazing.

Finally, hybrid window frames offer a bigger variety of aesthetics.  For instance, flush sitting vents, a fully glazed outside with no visible frame and unique window details.  Therefore, compared to single materials, hybrid offers far more choice in how windows and doors look both inside and outside.

Products available in hybrid materials.

Virtually every type of window and door is available with hybrid materials including:

  • Windows as casement, pivoting or tilt and turn and sliding sashes.
  • Shaped, apex and gable windows.
  • Bifolding Doors.
  • Tilt and Slide and Lift and Slide patio sliding doors.
  • Single doors and French Doors.
  • Front doors.
  • Facade glazing and floor-to-ceiling windows.
  • Rooflights and roof windows

For wood-aluminium products, aluminium on the outside protects the timber inside from external weather and moisture. The wood on the inside is therefore always protected and is maintenance free.

You also get all the advantages of aluminium with the full range of over 200 RAL colour palette.  Inside, the wood comes either as natural, painted or stained. Many hybrid brands also offer a choice of aluminium capping on the outside such as contemporary, softline or shaped.

The engineering on hybrid windows allows excellent security with multi-point locking systems, corner locking and a big choice of window and door furniture.

Environmentally-Friendly Hybrid Windows and Doors.

Virtually all hybrid glazing is sustainable as we ass environmentally friendly.  The aluminium exterior is 100% recyclable.  The profile in some brands already includes recycled aluminium.  Furthermore, most hybrid systems ensure material suppliers are carefully chosen and even manufacturing processes help produce eco-friendly windows.

The wood used in hybrid windows is from sustainable sources, PEFC certified (Programme for the Endorsement of Forest Certification) or certified to The Forest Stewardship Council (FSC®) standard.   Most suppliers making these windows also adopt strict Quality Management Systems as well as Environmental Management and Audit systems.

The choice of wood finishes available inside is extensive. Engineered timber, oak, pine, spruce, larch, redwood and Eucalyptus are just some of the fine woods used.

As a result of all these environmentally friendly materials and methods, hybrid windows enjoy an extended lifespan compared to single materials.

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.

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.
