The Most Thermally Efficient Aluminium Entrance Doors Available in Wales

March 5, 2025 by Sapphire Windows

Are Our GERDA Aluminium & Steel Doors The Most Thermally Efficent Entrance Doors Available In The UK?

Our GERDA doors are some of the most thermally efficient entrance doors available today. Our entry-level GERDA Optima door is capable of achieving an impressive overall U-Value of 1.0 W/m2K. Our GERDA Premium, Prime & Altus doors are achieving U-Values equivalent to and better than the Passivhaus standard.

Our luxury Gerda front doors have a thermal break technology and high-performance insulation barrier built into their very structure, which protect against even the most inclement of weather. GERDA doors are specifically designed to offer the best thermal efficiency and extremely low U-Values, providing the lowest CO2 emissions associated with reduced energy consumption and considerable savings in heating bills.

The Superiority of an Aluminium & Steel Front Door

Entrance doors go through a lot of wear and tear. Banging open and slamming shut. The outside is vulnerable to the hot summer sun, icy cold winters, and everything in between as our seasons change. Boisterous school children will stomp in and out, clouting the door with bags and skateboards and friends, scuffing the paintwork and denting the surfaces. Frantic dogs will scratch and whine, desperate to be let in or out when nature calls and it’s time for a walk!

A cheap front door will quickly show signs of deterioration when faced with even half of the above. Already prone to warping and bowing, even in our milder UK climate, all it takes is a cold nap or heat wave to speed up the process. In no time at all, your cheap front door is looking scuffed and spent.

The locks are compromised, and anything remotely ‘weatherproof’ is now compromised.

To be reassured of a satisfying ‘thunk’ every time you come through your front door, you need to be closing a Gerda door.

Choosing a steel front door will immediately remove all those elements of wear and tear that cause cheaper doors to deteriorate. Your steel front door will stand guard against the daily assaults without any erosion of those features that give it strength and beauty.

That is because the steel and aluminium construction of the entrance door has been superbly engineered to maximise the strength of both the door itself and all internal and external components, such as the locking system and hinges.

The superior strength of the steel front door means that it can withstand a pounding that would cause other doors to break and buckle.

“Crittall Style” Internal Doors Wales

February 18, 2025 by Sapphire Windows

What are "Crittall Style Doors"

Crittall-style doors are steel-framed doors with slim sightlines and large glass panels, often featuring a grid-like pattern of metal bars. They originated from the Crittall Windows company in the UK, which pioneered steel-framed glazing in the late 19th and early 20th centuries. Today, “Crittall-style” refers to any doors with this distinctive industrial aesthetic, even if they are not made by the original company.

These doors are popular in both modern and industrial interior designs, commonly used as:

Internal partitions to separate spaces while keeping an open feel
Internal doors to replace existing solid doors
Shower screens in bathrooms

They offer a sleek, minimalist look while maximizing light flow and creating a sense of space.

Why are "Crittall Style" doors so popular?

Crittall-style doors are popular because they blend functionality with a sleek, timeless aesthetic. Here’s why they’re so in demand:

1. Maximizing Natural Light

The slim steel or aluminium frames allow for larger glass panels, letting in more natural light and creating a bright, open feel.

2. Versatile Design

They work in various styles—industrial, modern, Scandinavian, or even traditional homes—adding character without overwhelming a space.

3. Creating Zones Without Closing Off Space

Unlike solid walls or wooden doors, Crittall-style doors define spaces while maintaining an open-plan feel, making them perfect for room dividers.

4. Industrial-Chic Aesthetic

Their black metal frames and grid patterns give off an effortlessly cool, urban vibe that complements both contemporary and vintage interiors.

5. Durability & Strength

Steel and aluminium versions are robust, long-lasting, and require less maintenance than timber doors, making them a practical choice.

6. Customization Options

They come in different finishes, colours, and glass styles (e.g., frosted, reeded, or clear), allowing homeowners to tailor them to their style.

Would you consider installing them in your home?

Unveiling the Beauty: Exploring the Elegance of Internal Steel Look DoorsSave

January 8, 2025 by Sapphire Windows

Step into a world of elegance and sophistication with internal steel-look doors. These architectural masterpieces are the epitome of modern design, seamlessly blending function and style. With their sleek frames and large glass panels, these doors create an illusion of spaciousness and bring an abundance of natural light into any space.

Crafted with precision and attention to detail, internal steel-look doors are more than just an entryway; they are a work of art. From residential homes to commercial spaces, these doors make a bold statement and add undeniable charm to any interior.

Whether you prefer a minimalist aesthetic or a more industrial look, internal steel look doors can be customised to suit your taste and complement the overall design of your space. Their timeless appeal and durability make them a worthwhile investment that will continue to impress for years to come.

Discover the allure of internal steel-look doors and unlock the potential of your interior design. Embrace the beauty and elegance they offer, and transform your space into a captivating showcase of style and sophistication.

Advantages of Internal Steel Look Doors

Internal steel-look doors offer a range of advantages that make them a popular choice for both residential and commercial spaces. One of the most significant benefits is their ability to enhance the aesthetic appeal of any interior. With their sleek, modern design and large glass panels, these doors create a sense of openness and light, making spaces feel larger and more inviting. They serve as a stunning focal point, drawing the eye and adding sophistication to any room. The minimalist yet striking nature of steel-looking doors aligns perfectly with contemporary design trends, making them a desirable option for those looking to elevate their interiors.

Another key advantage is the durability of internal steel look doors. Unlike traditional wooden doors, which can warp, crack, or become damaged over time, steel doors are built to withstand the test of time. They resist scratches, dents, and other forms of wear and tear, making them a long-lasting investment for homeowners and business owners alike. This durability ensures that internal steel-look doors maintain their beauty and functionality for years, making them an excellent choice for high-traffic areas.

Furthermore, these doors offer excellent insulation properties. The combination of steel frames and energy effiecent glazing in the glass panels helps regulate temperature, keeping interiors comfortable regardless of the season. This energy efficiency not only contributes to a more pleasant living or working environment but can also lead to lower energy bills over time. In summary, the advantages of internal steel look doors extend beyond aesthetics, encompassing durability, safety, and energy efficiency, making them an ideal choice for any space.

Different Styles and Designs of Internal Steel Look Doors

When it comes to internal steel-look doors, there is a wide variety of styles and designs to choose from, catering to different tastes and architectural preferences. One popular style is the industrial design, characterised by its raw, unfinished look that embraces the beauty of metal and glass. These doors often feature black steel frames and expansive glass panels, creating a striking contrast that works well in modern homes or office spaces. The industrial aesthetic is versatile, allowing it to pair seamlessly with exposed brick, concrete, and other materials commonly found in urban environments.

Another appealing option is the minimalist design, which emphasizes simplicity and clean lines. These internal steel-look doors often have slimmer profiles and may feature frosted or clear glass, allowing for natural light to flow while maintaining privacy. Minimalist doors effortlessly blend into contemporary interiors, contributing to a serene and uncluttered atmosphere. This style is particularly popular in modern homes and spaces where a calm and peaceful ambience is desired. The understated elegance of minimalist steel look doors can enhance a variety of design themes, from Scandinavian to modern farmhouses.

How to Choose the Right Internal Steel Look Door for Your Space

Selecting the right internal steel-look door for your space involves careful consideration of several factors, including your aesthetic preferences, the function of the door, and the overall design of the room. Begin by assessing the architectural style of your home or office. If you are working with a modern or industrial design, opt for doors with bold frames and expansive glass that enhance the sleekness of your interior.

Next, think about the specific function of the door. Will it be used as a room divider, or is it primarily for privacy? For instance, if you’re installing a door between two living spaces, you may want to prioritise transparency with clear glass panels that allow light to flow freely. Alternatively, if privacy is a concern, frosted or tinted glass can provide a stylish solution while still allowing some light to filter through. The functionality of the door should align with your lifestyle and needs, ensuring that it serves its purpose effectively.

Finally, don’t overlook the importance of space considerations. Before making a purchase consider the swing direction of the door and how it will interact with existing furniture and decor. If space is limited, sliding doors can be an excellent option, as they save room while providing access to different areas. By taking the time to assess your preferences and requirements, you can confidently choose the right internal steel-look door that enhances the beauty and functionality of your space.

Installation Process of Internal Steel Look Doors

The installation of internal steel-look doors is a crucial step that can significantly affect their performance and longevity. While it is possible to undertake this project as a DIY endeavour, hiring a professional installer is often recommended, especially for those unfamiliar with door installation. The first step in the installation process involves preparing the door frame. This includes removing any existing doors and ensuring that the frame is square, level, and free of obstructions.

Once the frame is prepared, the next step is to position the door within the frame. The installer needs to ensure that the door hangs correctly and operates smoothly. This may involve adjusting hinges, shims, and other hardware to achieve the desired fit. If the door features a sliding mechanism, tracks must be installed securely to facilitate smooth operation. It is critical to test the door several times during this phase to ensure it opens and closes without any hitches.

After the door is fitted and tested, the final step is to secure all hardware and make any necessary aesthetic adjustments. This may include caulking gaps or finishing exposed areas, and ensuring that the door locks and handles are functioning correctly. Proper installation is key to maximising the performance and lifespan of internal steel-look doors, ensuring they provide both beauty and functionality for years to come.

Maintenance and Care Tips for Internal Steel Look Doors

Maintaining internal steel-look doors is essential for preserving their beauty and ensuring their longevity. One of the primary maintenance tasks is regular cleaning. Steel frames and glass panels can accumulate dust, fingerprints, and smudges over time. To clean the glass, use a soft cloth and a gentle glass cleaner, avoiding abrasive materials that could scratch the surface. For the steel frame, a damp cloth is usually sufficient. It’s important to dry the surfaces afterwards to prevent water spots and maintain a polished appearance.

Comparing Internal Steel Look Doors to Other Types of Doors

When considering door options for your space, it’s valuable to compare internal steel-look doors with other types of doors available on the market. One common alternative is traditional wooden doors, which offer a warm and classic appeal. While wooden doors can add character to a space, they are often more susceptible to warping, cracking, and damage from moisture over time. Steel-look doors, on the other hand, boast superior durability and resistance to the elements, making them a more reliable choice for high-traffic areas or spaces with varying humidity levels.

Another comparison can be made with glass doors. While fully glass doors allow for maximum light and visibility, they may lack the structure and security that steel frames provide. Internal steel-look doors combine the best of both worlds, offering substantial glass panels within a robust steel frame. This means they can enhance the aesthetic of open spaces while also providing the security and durability associated with steel construction. Additionally, steel-look doors can be more energy-efficient due to their insulation properties, making them a practical choice for energy-conscious homeowners.

Finally, consider the differences between modern designs and traditional options. Steel-look doors exude a contemporary vibe that aligns beautifully with current design trends, while traditional doors may not offer the same level of modern sophistication. The sleek lines and expansive glass of steel look doors can dramatically enhance the overall aesthetic of a space, appealing to those who appreciate modern architecture. Ultimately, the choice between internal steel-look doors and other options will depend on your specific design goals, functional requirements, and personal preferences.

Cost Considerations and Budgeting for Internal Steel Look Doors

When planning to install internal steel look doors, it’s essential to consider the cost implications and budget accordingly. The price of these doors can vary significantly based on several factors, including the size, design complexity, and materials used. Typically, custom-made steel look doors tend to be more expensive than standard options due to the additional craftsmanship involved. It’s wise to obtain quotes from multiple suppliers and compare prices before making a decision, ensuring you find a balance between quality and affordability.

Additionally, factor in the cost of installation. While some homeowners may opt to install the doors themselves, hiring a professional can ensure a proper fit and finish. Professional installation may add to the overall cost, but it can save you time and prevent potential issues down the line. Be sure to include any additional costs for hardware, such as handles, locks, and hinges, in your budget to avoid unexpected expenses.

Lastly, consider the long-term value of investing in internal steel look doors. While the initial outlay may be higher than other types of doors, their durability and low maintenance requirements can lead to cost savings over time. Additionally, their modern appeal can enhance the value of your property, making them a worthwhile investment. By carefully considering all these factors, you can create a realistic budget that allows you to enjoy the beauty and functionality of internal steel look doors in your space.

Popular Brands and Manufacturers of Internal Steel Look Doors

When searching for internal steel-look doors, it’s important to explore reputable brands and manufacturers known for their quality and craftsmanship. One prominent name in the industry is Crittall, a brand synonymous with elegant steel doors and windows. With a heritage dating back to the early 19th century, Crittall has established a reputation for producing high-quality products that blend timeless design with modern functionality. Their internal steel-look doors are available in a variety of styles, allowing homeowners to find the perfect match for their interiors.

Conclusion and Final Thoughts on Internal Steel Look Doors

In conclusion, internal steel look doors represent a remarkable fusion of style, durability, and functionality. Their elegant design adds a touch of sophistication to any space, whether in a modern home or a commercial setting. As you consider this option for your interior design, remember the numerous advantages they bring, including enhanced natural light, energy efficiency, and a timeless aesthetic that complements various architectural styles.

The wide range of styles and designs available allows you to find the perfect door that suits your personal taste and the unique needs of your space. From minimalist to industrial designs, these doors can transform the ambiance of a room while providing practical benefits that enhance your living or working environment. Moreover, the proper maintenance and care will ensure that these doors continue to impress for years, making them a worthwhile investment.

Sunflex SVG v Cortizo Corvision v Origin OS29 Slim Aluminium Sliding Doors

July 24, 2024 by Sapphire Windows

A few years ago we started our journey to find the best aluminium sliding doors in the UK.

While conducting our research there were five important qualities which we were looking for, these were:

The overall quality of the finished product
Slim sightlines
Ease of operation
Thermal performance
Peace of mind for our 10-year company guarantee & beyond

Our journey began online and took us to numerous sliding door showrooms across the UK where we tried and tested doors from brands such as Sunflex, Cortizo & Origin.

Below are our comparisons between the Sunflex SVG, Cortizo Corvision & Origin OS29 aluminium sliding doors.

The overall quality of the finished product

To be assured of our decision we needed to know where the doors were being fabricated and by whom. Both Sunflex & Origin doors are manufactured in-house at one fabrication facility. Several fabricators manufacture Cortizo doors throughout the UK.

Knowing that the products are manufactured in one place, offers us assurance that the quality and attention of detail we expect is mainated & in the event of an issue arising in the future, it can be resolved by one party promptly.

There are also some features and attention to detial of the Sunflex SVG doors that exceeded our expectations. The Sunflex doors fare flush stacking, allowing each panel to stack neatly behind the neighbouring frame. They also offer a range of high-quality door handles which don’t interfere with the view through the glass panels.

Slim sighlines

Slim sightlines are often an important consideration for our customers, therefore achieving the slimmest sightlines is also important to us.

The Sunflex & Cortizo doors offer a slim 20mm sightline. The Origin OS29 achieves a sightline of 29mm, which is only 9mm larger. However, the depth of Origin OS29 is far larger than the Sunflex & Cortizo doors.

This means that the Sunflex & Cortizo doors look slimmer from any angle.

Ease of operation

Aluminium sliding doors on the whole offer a better ease of operation than their uPVC counterparts.

From the doors we have seen and tested, the Sunflex SVG doors lead the way in ease of operation.

They open and glide effortlessly thanks to their stainless steel quad wheel running carriage & stainless steel track. Ensuring the opening operation is smooth and should stand the test of time.

From our knowledge the Origin OS29 uses nylon wheels on the running carriage and an aluminium track. Stainless steel would be a better solution.

As the Cortizo doors are manufactured by a number of different fabricators it isn’t possible to know the running gear and tracks used as it will vary for each fabricator.

Thermal performance

Optimum thermal performance is important to reduce both heating bills and our carbon footprint.

For replacement windows & doors, the whole window/door U-value must not be higher than 1.4 W/m2K. All three systems can achieve the required 1.40 overall door U-value. The Sunflex SVG doors achieve the required 1.40 with a glass centre pane U-value of 1.0. The Cortizo Corvision achieved the required 1.40 with a glass centre pane of 1.0. The Origin OS29 achieve the required 1.40 with a glass centre pane of 0.8.

Therefore the Sunflex & Cortizo doors lead the way in achieving the required U-value and offer the best thermal performance.

Peace of mind for our 10 year company guarantee & beyond

As a business we offer a comprehensive 10-year guarantee, therefore when choosing a product, it’s vitally important that we have confidence the product will offer us complete peace of mind that it will perform with little maintenance for 10 years and beyond.

Both Sunflex & Origin doors are manufactured in-house at one fabrication facility. Several fabricators manufacture Cortizo doors throughout the UK. In the event of an issue arising in the future, we want peace of mind that the issue can be resolved by one party promptly.

The Sunflex SVG sliding doors & Origin OS29 are mainly glazed with internal glazing beads. This means if you ever had to replace the glass in the future it can easily be removed and replaced. With some slim sliding systems like the Cortizo Corvision, the glass is bonded all round to the aluminium. This means that if the glass ever needs to be replaced in the future you would also need to order a new door panel or new set of doors if that panel is no longer available.
