Manchester extension with bifold doors and windows

Aluminium windows and doors for a modern extension

One of our recent installations of Aluna bifold doors in Manchester, to a new build extension at the back of a traditional home. Completed in the summer, the installation includes a four-pane bifold, a three-pane bifold, and a combined door and window set.  All powder coated in the popular RAL 9005 black matt finish inside and out, with matching black hardware and high performance glass units. 

This project forms part of a contemporary brick-built extension to a detached home with a gable roof. The homeowner wanted a glazing solution that would open the living area to the garden while maintaining visual contrast against the brickwork. The chosen black finish achieves that perfectly — bold, modern, and timeless.

At the side elevation, a single entrance door is coupled with windows, some having opening fanlights. This provides a highly accessible entrance with added ventilation. Th remaining two elevations have Aluna bifold doors, at reduced sizes to create folding windows.  There is a further bifold door set separating the main house from the extension as well.

Aluna bifold doors. Slim, strong, weather resistant

The Northwest of England can have some very wet and windy weather, and our client wanted the reassurance of a weathertight bifold and door system.  The Aluna doors come with extensive sealing throughout. Every door is operated by a multipoint system, meaning the folding sashes are pulled tight against the outer frame, seals and gaskets. 

Expertly-crafted and professionally installed, Aluna bifold doors are now one of the most popular in the UK, because of their outstanding price to quality point.  And they come with similar sightlines and performance to the more expensive German systems but at a substantially reduced price and significantly faster lead times. 

For our homeowner customer the slim 107mm sightlines provide more glass and less visible frame, with no loss of strength or security.  Aluna doors are security tested to the latest standards, come with premium grade aluminium and a Qualicoat-assured colour finish inside and out.  

The glass provided throughout is toughened safety glass, having a soft-coat low-emissivity coating, warm edge spacer bars and argon gas fill. 

PRECISION SURVEY AND EXPERT INSTALLATION

As with every Fenestration Network bifold door across our many quality brands, project, this installation started with a professional survey and close coordination with the supplier to ensure timely delivery. Our team managed all communication with the homeowner and worked around the construction schedule, guaranteeing an accurate fit and smooth installation.

The result is an installation that enhances the property both visually and functionally — clean sightlines, smooth operation, and consistent quality throughout.

Customer Testimonial

I got an email the next day from Tom at the Fenestration Network and they have been very quick and very responsive on the project. So much so that we went with them for this job — they were very helpful and had a survey booked within a week.

From the first contact, Tom was professional and responsive. We provided approximate sizes for our bi-fold doors and windows, and within 48 hours Tom came back with a detailed quotation and full drawings suggesting top openers on one side.

My experience has been first class. I previously worked in the architectural industry for 12 years manufacturing these types of products and was impressed by how this company operates.

The installation team, Matt and Gary, were excellent and took great pride in their work. The end result has given us a fantastic room that we can use all year round.

I would have no reservations in recommending this company for any future projects.

The Fenestration Network works differently from most window and door companies. We’re an independent, owner-managed business built on communication, integrity, and genuine expertise. We partner only with proven manufacturers and brands we know and trust that will enhance your home with better security, energy-efficiency and style. 

With our White Glove Service, we manage every detail — from advice and quotation through to survey, installation, and aftercare. The result is a complete, fully coordinated service that ensures peace of mind and the highest standards every time.

We were originally going to order our patio doors supply only and get our builders to fit them, but after reading some of the advice from Nick at doorandwindowexperts we realised it was too big a risk for such an important and expensive purchase. Nick recommended Tom at The Fenestration Network and from the very first contact we felt really looked after; no question/query was too much trouble and we received a truly individual service. We opted for the full survey, supply and fit even through it stretched our budget and I'm glad we did. The communication was great, the lead time was reasonable and the fitters were really lovely. We are very happy with our new doors! 😊

Fantastic service from start to finish Tom was great to deal with along with the Survey meeting the lads before they started to double check everything. The fitting team turned up on time today with the delivery also was almost finished for 11 o’clock very impressive., Considering the size of the units and the Power needed to do this job was very difficult and had to be thought out and planned correctly they nailed it, the trimming and silicone’s skills were second to none . Will look forward to using this business again for any window door installation , large profile glass installation.Etc

Fenestration network have supplied and fitted some top class bi-fold doors in our extension project.
A clear payment plan which is in line with all top window/door suppliers
Good communications throughout the process
The company was found with assistance of an online expert who is keen to advise on reliable, expert supply and fit companies at a reasonable price, not expensive like some other companies I visited.
If you have a building project I would recommend Fenestration Network, make contact and speak with Tom.
They will be able to advise on different types of doors depending on your requirements.
I would highly recommend you contact Febestration Network for stunning, top quality, High end doors.

I have really enjoyed working with The Fenestration Network. Every job I have been involved in has been exactly as described, with the team always being friendly and professional. When I have been on site to capture footage of properties with new glass and glazing supplied by them, the installations have looked amazing both in person and on camera.

Customers I have spoken to while on site have also told me how impressed they are with the quality of the products and services provided by The Fenestration Network.

From a drone filming and marketing perspective, the aluminium glazing products, windows, doors, and bi-folds have been fantastic. They come in a wide range of colours, which not only gives each home a unique look that perfectly matches and complements the property, but also makes the promotional videos stand out with variety and style.

The Fenestration Network clearly delivers exactly what their customers want, both in quality and in choice.

We had windows and doors supplied and fitted by Tom and his team and apart from their prices being very competitive, the quality, look and service was excellent. To add to this, Tom gave us a discount for allowing him to have a drone take pictures which will happen once all the rendering is finished. I would highly recommend them to anyone. Thank you Tom and the team

I contacted Tom Evans of The Fenestration Network for my recent, significant, aluminium window supply and install project. I found Tom easy to work with and thorough on endeavouring to get everything right before the project started. There was no pressure to rush things, but he was quick to action anything needed. The installation team he used in my area of the country was polite, hard working and personable. Overall, I valued his high personal integrity displayed thoughout the project.

From the first contact with Tom from the Fenestration Network they were very professional and very responsive.. They had been passed our project idea and I gave approximate sizes for bi-fold doors/windows for our outside terrace…

We wanted to fully enclose it, within 48 hours Tom came back to me with a priced quote which was exceptional…. Full detailed drawings of each view suggesting top openers on one side…. My experience has been first class, I have previously been in the Architectural industry for 12 years manufacturing these type of products and was impressed how this company worked.

I agreed the price and within 1 week Tom had arranged for a site survey to finalise the dimensions…. The installation team that Tom used for the survey and installation were very good and very keen to do a fantastic job, the 2 guys (Matt & Gary) couldn’t do enough for us.

The end product was a great addition you our property giving us a fantastic room which we can use all year round.

I would have no reservations in recommending this company for any projects you are planning in the future…

See attached video of the finished project.

We used The Fenestration Network for the replacement and installation of all our windows and patio doors as part of our renovations. We ran into some difficulties during the installation but the team were dedicated to getting us back on track! Would recommend to others looking for window and door installers.
