Window and Door Hardware

Window and door hardware comprises not just locks and handles, but other components used in manufacturing, assembly as well as window functionality. Without hardware, aluminium windows or doors don’t function as intended or even come together.

Some information about window and door hardware

The types of aluminium window and door hardware vary for residential or commercial glazing. Other components provide specific requirements, such as a particular security operation or safety feature.

Generally speaking, aluminium systems companies design their products around standard components available from many different manufacturers of hardware. Alternatively, they may get a component designed specifically for their product. Solarlux bifolding doors are one example where handles, hinges and other significant components are their own design, for their doors only.

As another illustration, Debar Hardware makes bifolding door components. You’ll find Debar hardware used extensively on Cortizo, Smart Systems and other brands of bifolding doors.

Another reason for using some standardisation for components, locks and handles is easy replacement on older doors and windows.

Security, weather performance and reliability come as standard with most well-designed windows. While it may be true that it’s the window or door that’s tested as a hole product, each individual component also comes with it’s own certification. Locks, gaskets, handles and key cylinders all meet separate quality and conformity standards as a stand-alone product.

Window locks and handles

Modern aluminium windows come with different locking systems, matched with suitable locking or non-locking handles.

Generally speaking, the must-point locks on a window work with different types of handles. Therefore, they don’t come as one complete unit.

As a result, you’ll find the same locking systems on contemporary windows as heritage or steel-look systems. It’s the handles such as art-deco or monkey tail, setting off the more traditional aluminium window for an authentic look

Door locks and handles

Doors naturally come with high expectations for security. Here, designers opt for some of the best brands.

Winkhaus, Union, ASSA, Siegenia, Mila and others are all well-known brands of locks, supplied to many aluminium doors.

Just like windows, locks marry up with different styles, brands and types of door handles. These therefore give the required look and functionality. For instance, some locks work with their door handles, others as standalone units with separate door pull handles.

Trickle Ventilators

The trickle ventilator is often required in new doors and windows. Specifically, new build homes or new extensions require these as part of current Building Regulations.

Trickle ventilators come in many colours and types. You’ll find them fitted at the frame head with residential windows and doors.

Commercial buildings also use the glaze-in types, sitting above the double glazed unit. For dwellings, the need for trickle ventilators can confuse. Where outgoing (old) windows have trickle ventilators, the new ones must also have them. Titon, Renson and Greenwood are three of the best known manufacturers of window and door ventilators.

Patio door hardware

For large patio doors especially, the hardware used must be safe.

At the same it, these complex components allow the smooth sliding of patio doors and easy use of bifold doors.

Rollers, guides, tracks and other protection systems all work together for even the biggest patio doors.

Seals and Gaskets

Another crucial component in all windows and doors are the seals and gaskets. These come in EPDM rubber, Q-Lon, woodpile and other types and materials.

The seals found in every window is absolutely essential in preventing water ingress and general sealing. Gaskets also play a critical role in keeping glass safe and secure.

Reddiplex and Schlegel are two of the best known brands for window and door seals. These essential window and door hardware components protect, seal and help with the operation of all windows and doors. Frameless doors and windows rely on these especially, given their minimal look and lack of frame.

Window and door hardware in manufacturing

The manufacturing of any window or door requires essential hardware, therefore bringing the various frames together.

Some aluminium components such as corner cleats, brackets and ties, come as full aluminium bars. Then these are cut-down to the required size.

Other components include chevrons for windows, cleats for doors, mechanical joining pieces, screws, rivets and sealants. Every one of these products comes specified by the designers of the product. Some of this window and door hardware is designed by the systems company. Others are generic hardware available from multiple suppliers.

Hardware for specialist or specific use.

Thousands of different window and door hardware products serve residential and commercial glazing with a specific use.

For domestic properties, some familiar examples include window restrictors or fire-escape hinges.

In commercial, retail and specialist buildings, window and door hardware are again extensive. Card readers and access control. Anti-ligature furniture, panic and crash bars on fire doors, even automatic doors in hotels, shops and offices. Multiple manufacturers, suppliers and providers enable the best safety, security and protection of windows and doors. The variety and type of commercial door and window hardware remains incredibly hard to list in full.

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.
