Aluminium Windows in Cumbria – Case Study

A distinctive installation of aluminium windows in Cumbria, complemented with matching Heritage-style doors. Set in a small village near Kirkby Stephen, this traditional stone property now benefits from the authentic steel-look design of the Alitherm Heritage system in a contemporary RAL 7016 Grey finish.

Working within the original structure and newly built openings, our aluminium windows are set into old and new stone surrounds and seamlessly integrate with the building. Modern aluminium glazing with the timeless styling of period metal windows.

Alitherm Heritage Windows and Doors

This project showcases 20 aluminium windows and 5 aluminium doors, all designed using the Alitherm Heritage system — the UK’s leading steel-inspired glazing solution.

Alitherm windows and doors all come with premium-grade aluminium, finished with durable powder coating to Qualicoat standards. All profiles come with a polyamide thermal break, high-specification insulated glass units, safety glass in low level windows and all doors. Durable premium and stylish door and window handles, finish off each product. We think there is no better aluminium system replicating the timeless style of traditional steel.

Why Choose Alitherm Heritage?

Alitherm Heritage remains the UK’s best-selling steel-look aluminium system, trusted for its authentic detailing, slim profiles, and proven durability. With options for windows, doors, and internal screens such as Smarts Aluspace, it provides the ideal solution for homeowners wanting Art-Deco, industrial, or heritage-inspired glazing without compromising on energy efficiency or security.

Aluminium Windows in a Grey Finish

Black is one of the most popular colours for this style of home. However, our customer chose the contemporary RAL 7016 Grey to provide a bold contrast against the natural Cumbria stone. The end result of grey against cream looks outstanding.

Window designs included top-hung outward-opening configurations for the larger, contemporary apertures and a combination of side-hung casements with fixed panes for the more classically styled areas of the home. First floor side hung windows also come with fire-escape hinges.

Thanks to the unique architecture, these steel inspired aluminium windows in Cumbria have openings staggered across multiple levels, adding visual interest and depth to the stone façade. A tall, fixed picture window installed into the stairwell provides masses of natural light into the heart of the property.

Each unit is glazed with 28mm insulated glass units, incorporating a soft-coat low-emissivity coating, argon gas fill, and warm-edge spacer bars. Safety glass was used throughout, and all frames sit neatly within the original stone surrounds.

Our steel look doors replicate the proportions and style of traditional metal doors while offering shorter lead times, greater energy efficiency, and a more cost-effective solution. Doors are glazed with toughened safety glass, having a soft-coat low-emissivity coating, warm edge spacer bars and argon gas fill.

Heritage Style Aluminium Doors

At the front of the property, an imposing entrance screen combines a single Alitherm Heritage door with matching side panels and a steel-look toplight. Mullions and transoms run consistently through the horizontals. Coupled frames also have similar sightlines on the vertical elements, dividing the aluminium entrance screen into twelve modules.

Every detail is colour-matched in RAL 7016 Grey, including the door handle and hinges, creating a matching and architectural-quality throughout.

Around the ground floor are a selection of single doors with side panels. These all incorporate a top-hung opening vent in the upper module to provide natural ventilation. As with the windows, all doors come with premium multipoint locking systems, high-security key cylinders, and toughened safety glass.

Precision Window Installers in Cumbria and Nationwide

This installation of aluminium windows in Cumbria required careful planning and expertise. All windows were fitted directly into the original stonework and traditional stone cills, with face-drained systems ensuring proper performance without the need for additional aluminium cills.

Our professional survey team coordinated closely with the supplier to ensure timely delivery, while our installers worked with precision on site. The result is a project completed to the highest standard, with a delighted customer enjoying the perfect combination of heritage style and modern aluminium performance.

Given the stonework and its uneven surface, even the mastic sealing around the perimeter frame and structure has to be carefully applied.

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

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.
