The latest design features with high specifications

All Origin doors and windows are synonymous with high-grade aluminium and the finest door components.  The bottom rollers and guides are hard-wearing and durable. As well as this, they provide a smooth glide action, from two panels up to 6 or more.

Security and Energy Efficiency

Energy saving and always protecting your home

Slim and strong aluminium and the latest aluminium profile insulation provide low U-Values down to 1.2Wm2K, keeping your home warmer in winter and lowering your heating bills.

Origin is a pioneer in high security locking system. No less than 8 locking points, robust zinc hinges and built-in protection features ensure these large glass doors provide optimum security with great views.

Strength, security and energy efficiency as standard

The polyamide thermal breaks within the aluminium profiles throughout your doors prevent the transfer of cold to the inside.  The aluminium then combines with high specification glass units with excellent U-Values double glazed and even better triple glazed.  Your new doors surpass current Building Regulations for energy efficiency too.

Multiple locking points on the master door keeps the lead doo secure and intermediate leaves have bolts securing them at the top and bottom. Security cylinders come with quality keys and designed against snapping, picking or drilling. Internal glazing beads prevent removal of the glass from the outside.

Appearance and Customisation

Create a truly personalised door in your home.

Origin doors are at the forefront of made to order with the most comprehensive options for colour, glass and hardware.

Choose your size, the number of panels and how they open.  Then you get a choice of over 150 other shades.  Then you get an incredible choice of designer handles in several colour options.  Finally is the choice of glass for your desired levels of privacy, comfort or security. There’s even an open corner bifold option.

Your new bifolding door designed around you

The colour options we have available for you are extensive.  Shades of Grey and Black are the most popular, however, there’s also the option of dual colours, metallic and even woodgrains to work with your home and decor. With the finest quality professionally applied finishes, your door will look great for years with only routine cleaning with a mild soapy solution.

For your new door handles, as standard you get the luxurious Hafi contemporary handle with a separate key cylinder, setting off these modern doors to perfection.  You can also choose matching or contrasting colour handles and even the door rollers.

Best of all with Origin, where other doors only provide black gaskets and door seals, these doors come in a choice of 7 different colours for a fully colour-matched bifold.

Thanks to ‘Aluhome’ for first class (well Informed) advice with regard to the suitability of replacing our existing ... French doors with a Less obtrusive Aluminium framed Sliding Door system.What a difference! - the views into our garden now they are clear of window frame obstructions is delightful. This coupled with more natural light to the interior, is another bonus.The installation was carried out by fitters who clearly knew their trade and with the minimum of inconvenience to us.We are happy to report that the finished job from appearance, practicality and quality, exceeded our expectations.read more

Tim and his amazing team have been a godsend during our extension project. His advice and friendly chats together with... his highly experienced team of surveyors and fitters made the whole experience simple and hassle free. What he doesn’t know about his products isn’t worth knowing and we came away from the showroom feeling knowledgeable and that we’d made a great informed product choice. A big thank you to the whole team, and I promise once the garden's done and the kitchen's in we will update our photos which currently I’m almost embarrassed to upload as they don’t do the bifolds justice at all! We love them, the light is amazing, thanks again Tim & Team!read more

Based on our recent experiences, we are happy to recommend aluhome. During a visit to their office and display room Tim... was able to give a comprehensive description and assessment of all aspects of the door and windows we were thinking of installing (replacing 25 year old wood framed patio doors and windows). The timing of delivery and installation was as predicted. The cost was more competitive than similar offers. The installation team were on time, friendly, competent and efficient. And they left the patio area as clean as it was beforehand. And we are now very pleased with our new patio door&window. Best wishes, Rick and Moread more

We used AluHome to design and fit steel-look replacement french doors and windows at the back of our house in central... Stamford. Tim and the team at AluHome have been outstanding all the way through the process. They took time to understand our requirements and communication has been exceptional throughout. There were no delays, the doors look wonderful and the installation team were prompt, knowledgeable and paid a high level of attention of detail. There is no need to look elsewhere, we strongly recommend Tim and the team.read more

Great experience from start to finish. Tim was extremely helpful in assisting us with the initial enquiry for French... doors and windows that needed a specific “U” grade for building regs. He invited us to the the showroom and gave us a thorough walk through of the products. The quality of the product is second to none. Aaron - in charge of fitting- worked closely with our builder in terms of planning and measuring as well as giving some on site advice and recommendations.The provision and installation was on time with no issues and very professional.The French Doors now form the focal point of our kitchen extension and have really made the project.We highly recommend Tim and Aluhome!read more

We visited Auhome to help choose doors for our new extension. We met Tim who was very helpful and extremely... knowledgeable and offered useful information to help me decide between sliders or bi folds. The showroom has a good choice of doors which again helped with our decision. I am delighted with the Sunflex sliders we chose, they completely make our room, great quality and fitted expertly by the team. Thank you Tim and all at Aluhome in Stamford. I would thoroughly recommend you.read more

A warm welcome at the showroom in Stamford which has a range of products on show. We were shown the options available... to us as we were looking to buy bifold doors. We were advised on what would suit us best and the various options available as regards colour, handle options etc. They were fitted very quickly and although we had a couple of issues they were dealt with quickly and efficiently by Tim. Very pleased with our doors and the service from Tim and his fitters. Would recommend.read more
