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.
Bi-fold doors can create a very wide open aperture because the panels fold away. Sliding doors can accommodate very large individual glass panels but usually leave part of the opening glazed. The best solution depends on whether you prioritise a fully open wall or expansive uninterrupted glazing.
Bi-Fold Doors are normally suitable for large openings, giving you a way to effectively remove a wall and bring light into your home.
It depends on the property. Triple glazing is often worthwhile in highly insulated new builds, exposed locations and homes with large glazed areas. In properties that already have good modern double glazing, the additional cost may not deliver a proportionate return in energy savings.
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. 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. All our glass roofs are made to measure. We manufacture in Britain, so we can cater to unusual dimensions, specific pitch angles and non-standard shapes without compromise.
Yes. With double glazing, weather seals, and thermally efficient materials (uPVC or thermally broken aluminium), our French doors significantly reduce heat loss and draughts, helping to lower your energy bills.
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. Builders, architects and developers can open a trade account with us. We offer supply-only on very competitive terms, complete with technical drawings, structural calculations and dedicated account management.
Extremely efficient. Thanks to the “thermal break” technology—a polyamide barrier separating the interior and exterior aluminium—they prevent heat transfer. Systems like the Schüco ASE 80 sliding door can achieve U-values as low as 0.99 W/m²K, which meets the rigorous Passive House standard. This keeps your home warm in winter and cool in summer.
Yes. Fingerprint systems like Schüco Fingerprint Easy support up to 20 users. With smartphone-based systems, you can grant access to family members, trusted friends, or service providers, with the ability to set permanent, temporary, or scheduled permissions.
Both are relatively low maintenance thanks to aluminium’s durability and weather resistance. Bi-fold doors have hinges and a folding mechanism that may require occasional cleaning and lubrication. Sliding doors have tracks and rollers that should be kept clean. Routine care keeps both operating smoothly.
No, they are generally very low maintenance. The steel or aluminium frames are typically galvanised and powder-coated to protect against rust, corrosion, and fading. Routine upkeep usually only requires wiping the frames and glass clean with a damp cloth and soapy water periodically. Unlike wood, they do not require regular repainting.
The cost varies significantly based on size, materials, and complexity. As a guide, a uPVC orangery starts from a higher investment than a standard conservatory due to its solid construction. We provide clear, fixed-price quotes after our initial survey so you know exactly what to expect.
Our flush fit windows are primarily crafted from advanced, multi-chambered uPVC. This material provides exceptional thermal efficiency, security, and durability, and is available in a huge range of smooth colours and highly realistic woodgrain finishes.
Quality aluminium sliding doors can be specified with multi-point locking and robust hardware. Security features vary by product and configuration, so it is important to choose a reputable system and professional installation.
If you are replacing existing doors, you won’t usually need planning permission to add bi-fold doors. However, if you live in a conservation area you may need to get further information from your local council before going ahead. If you plan to build an extension and add bi-fold doors it’s always best to check local building regulations before you start work.
Yes. Modern aluminium sliding doors incorporate thermal breaks, double or triple glazing and advanced weather seals, vastly outperforming older aluminium or timber patio doors. U-values can be as low as 1.2 W/m²K or better, meeting and exceeding building regulations.
Smart front doors combine high-performance door construction with electronic, biometric, or wireless technology to control locking and unlocking. They can be operated via smartphone apps, fingerprints, or remote access systems.
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.
