Now it is bright, warm, and a joy to spend time in

Frequently asked questions
The main differences lie in wall construction, roof design, glazing proportions and overall architectural appearance. Conservatories typically have predominantly glazed walls and roofs, while orangeries usually combine solid wall sections with large windows and a roof lantern.
Neither is universally better. The right choice depends on your property, intended use, budget and preferred design. An orangery may suit a kitchen-diner extension, while a conservatory may be ideal for a garden room or relaxation space.
Thermal comfort depends on the whole building design, insulation, glazing, ventilation, orientation and heating rather than the name of the extension alone. Both conservatories and orangeries can be comfortable year-round when properly specified.
A conservatory may have a lower starting cost in some cases, but specification, size, structural work and finishes can change the comparison. A high-specification conservatory can cost more than a simple orangery.
With suitable glazing, roof specification, ventilation, shading and heating, a conservatory can be used for much of the year. Modern glass roofs and solar-control glazing improve year-round usability.
Roof lanterns are a characteristic feature of many orangeries, but designs vary. The final configuration depends on the architectural approach and the homeowner’s preferences.
Yes, aluminium is a suitable option for many designs, subject to the selected system and project requirements. Aluminium offers slim sightlines and a contemporary appearance.
Yes. Modern uPVC systems offer design flexibility, low maintenance and appropriate thermal performance. uPVC is available in a range of colours and finishes beyond basic white.
Schüco windows stand out due to superior German engineering that delivers tangible benefits:
-
Better Energy Efficiency: Advanced thermal breaks often meet Passive House standards, drastically reducing your energy bills.
-
Stronger Security: Integrated, multi-point locking systems are certified to the highest anti-burglary ratings for maximum peace of mind.
-
Sleeker Design & Durability: They offer remarkably slim sightlines for more glass and less frame, all while being built to last for decades with minimal maintenance.
-
Precision & Quality: Every component is engineered to work together flawlessly, ensuring smooth operation and long-term reliability that cheaper alternatives can’t match.
In short, you’re investing in proven performance, security, and comfort, not just a window.
Triple glazing offers superior thermal and acoustic performance compared with double glazing. It’s worth considering for noisy locations, homes aiming for maximum energy efficiency, or properties with large glazed areas. However, it isn’t necessary for every property — a well-specified double-glazed window is more than adequate for many homes.
Absolutely. Aluminium bi-fold doors provide floor-to-ceiling glazing across a wide span, bringing huge amounts of daylight in and enhancing the indoor-outdoor connection. Even when closed, the large glass panels brighten the room.
Absolutely. While known for modern designs, aluminium doors are incredibly versatile. We offer a range of classic colours (like heritage greens and greys) and even wood-effect finishes. The slim sightlines can be designed to complement traditional architecture, offering improved performance without compromising character.
Combine large overhead glazing – like a lantern roof or flat skylight – with full-height aluminium sliding or bi-fold doors. Position the extension to capture the best orientation, choose open plan layouts, and specify slimline frames for minimal obstruction.
Yes. Modern uPVC systems offer design flexibility, low maintenance and appropriate thermal performance. uPVC is available in a range of colours and finishes beyond basic white.
Yes. To meet building regulations and ensure adequate background ventilation, we can integrate almost invisible trickle vents into the window head.
Yes, modern Crittall style doors are designed for efficiency. External doors typically feature double or even triple glazing and “thermally broken” frames (a layer of insulation between the internal and external frame) to prevent heat transfer. For security, external steel-framed versions often include reinforced glass and multi-point locking systems, making them highly robust.
With modern, acoustically optimised double glazing, the sound of rain is significantly dampened and is often described as a gentle, soothing patter rather than a loud noise.
The ADS 70.HI system is designed for outward opening, which is often preferred for better weather sealing and saving internal space. Inward opening variants are also available – just ask our team.
Absolutely. We provide 10-year product guarantees and a comprehensive installation warranty.
Lower is better. What counts as “good” depends on the project, the building regulations that apply and the whole-window figure (Uw) rather than the glass alone. Rather than chasing the lowest advertised number, ask for the whole-window performance of the specific system you are considering.
Lead times vary by design and specifications, but typically range from 4–8 weeks including installation.
We can supply with double or triple glazing, with options for self-cleaning glass, solar control, acoustic insulation, or decorative stained glass to match your home’s style.
Modern front doors typically incorporate advanced multi-point locking systems, stronger frames, and robust construction, which can enhance security compared to older wooden doors with basic locks.
They are ideal. Children can gain entry with a simple fingerprint without the responsibility of carrying a key. You can let them in remotely after school, and you always know who has come and gone.
Yes. Schüco doors can be equipped with biometric, keypad, or smartphone access systems for modern convenience.
Absolutely. Composite doors are available in a huge range of colours, finishes, glazing options and hardware styles. Whether you prefer traditional or contemporary, there’s a door to match your taste.
Schüco is a premium brand, and its price reflects its superior quality, performance, and longevity. While the initial outlay is higher than standard windows, they represent a long-term investment that adds significant value to your property, reduces energy costs, and enhances your quality of life.
Yes. All of our window installations are backed by a comprehensive, insurance-backed guarantee, giving you complete confidence and peace of mind in your investment. We stand by the quality of our manufacturing and the expertise of our installation.
