Choosing new windows and doors is a big decision for any homeowner. It is an investment in comfort, security, energy efficiency, and the long-term value of your home. At Sapphire Windows and Doors, our goal is to make the entire process simple, transparent, and completely pressure free.

From your first conversation with us to the day your new products are installed, we handle everything with care, honesty, and over 35 years of experience.

When you request a quote, you will usually meet Russell, one of our co-owners and an expert surveyor with more than 40 years of hands-on industry experience.

Experience That Makes a Difference

Russell has worked on homes across South and West Wales for decades. He has managed straightforward installations, complex bespoke projects, property renovations, and modern builds. His attention to detail and calm, knowledgeable approach are the foundations of our business.

At Sapphire, we are proud to offer advice and quotes in English or Welsh, depending on your preference.

He will also take initial measurements and complete a simple survey to understand your property.

This visit is relaxed, informative, and completely pressure free. We believe in giving you the information you need to make the right decision, not the quickest sale.

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.

State Of The Art Entrance Doors For The Homes of South Wales

We believe in bringing world-class home improvements to the people of Wales. As the trusted local distributor of GERDA Entrance Doors, we supply and install our innovative alumimium & steel entrance doors across South and West Wales, from Cardiff to St Davids, and Swansea to Aberystwyth.

The Most Thermally Efficient Bifold Door

March 4, 2025 by Sapphire Windows

Is Our Sunflex SF75ECO The Most Thermally Efficent Aluminium Bifold Door Available In The UK?

With its patented 44mm thermal break and outstanding design, the SF75eco is the most thermally efficient aluminium bifold door on the market today. When triple-glazed, the system can achieve an overall (frame plus glass) U-value of just 0.8W/m²K, making it suitable for even Passivhaus standard homes.

Specifically designed to offer the best in thermal efficiency and extremely low U-Value, providing the lowest in CO2 emissions associated with reduced energy consumption and considerable savings in heating bills.

Sleak & Slender Aluminium Frames

The challenge for architects has been incorporating bifolding doors that don’t just perform well but also actually look good in the finished design, and the SF75eco achieves that. With slender 117mm sightlines and panels up to 1.2m wide and 3.0m high, the doors maximise the glass area when closed and provide a seamless connection between inside and out when open.

Key Design Features

The SF75eco has been designed in Germany by SUNFLEX, utilising more than 35 years of folding door design. The system includes several innovative design features, including the patented panel catch and stacking clip technology that prevent the doors from being blown shut in the wind and the finger-safe gasket design that keeps little fingers safe as the doors are closed.

“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?
