The Schüco windows are in a league of their own.
The Schüco windows are in a league of their own. Our home is noticeably warmer, quieter, and looks stunning from the street. The slim frames let in so much more light than our old uPVC windows. The installation team was meticulous and professional throughout. Highly recommend for anyone considering aluminium windows.

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.
Some extensions may qualify as permitted development, but this depends on factors such as dimensions, location and property type. Always check with your local planning authority and consult a building professional.
Often, yes. This is a popular way to create access to a garden or patio. Our team can assess the structural feasibility during a free survey.
Yes. Modern uPVC windows benefit from significant advances in profile design, glazing technology, thermal insulation, and security. They typically offer better energy efficiency, improved weather resistance, and enhanced security compared with older uPVC windows. The choice of colours and finishes is also far wider today.
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.
Bi-Fold Doors are normally suitable for large openings, giving you a way to effectively remove a wall and bring light into your home.
Flush-fit windows have a sash that closes level with the outer frame, creating a smooth, continuous surface. This mimics the appearance of traditional timber joinery and suits both period and contemporary properties. They are a popular alternative to standard casement windows for homeowners seeking a more refined look.
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.
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.
Absolutely. This is one of the key benefits of an orangery. Its solid structure and integrated feel make it perfect for use as a kitchen, dining room, main lounge, or even a home office.
Yes. Modern thermally broken aluminium systems are designed to carry deeper, heavier glazed units while maintaining slim sightlines. The frame profile and system need to be specified appropriately for the weight and depth of the glazing.
Yes. The inward-opening “turn” function allows you to easily reach and clean the outside pane of glass from within your home
Schüco Bi‑Fold Doors are a range of aluminium folding door systems manufactured by Schüco International, a leading German brand. They are designed to concertina to one or both sides, opening up large apertures with slim frames and high‑performance glazing.
Yes, they are an excellent choice for upstairs rooms due to their secure ventilation and the ease with which the external glass can be cleaned from inside.
While the initial investment for a composite door is higher than for a standard uPVC door, they offer significantly better performance, security, longevity, and aesthetics, representing far greater long-term value for your money.
Simply use a soft cloth and warm, soapy water. Avoid abrasive cleaners or pads that could scratch the surface. The glass can be cleaned with standard glass cleaner.
High-quality uPVC windows have a life expectancy of 30-35 years or more. They are incredibly durable and are backed by extensive guarantees, which we are proud to offer on our products and installation.
Security is a core principle of Schüco engineering. All systems feature multi-point locking mechanisms as standard, along with integrated finger-trap protection and anti-lift devices on sliding doors. The inherent strength of the aluminium profile itself makes it extremely resistant to forced entry, and many systems meet stringent security standards like PAS 24.
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.
No, they are very low maintenance. An occasional clean with warm soapy water is all that is usually needed to keep frames looking their best. They do not require painting or special treatments like timber windows.
Generally, yes. While aluminium is very strong, uPVC is a natural insulator. Our multi-chambered uPVC profiles create a thermal barrier that prevents heat from escaping, often achieving higher energy ratings (A or A+) more cost-effectively than aluminium frames.
