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.
You won’t be locked out. Depending on your configuration, you can use a registered fingerprint, a backup keypad, or a mechanical override that can be accessed securely. We will ensure you have a reliable backup method during the design consultation.
Quality uPVC from reputable manufacturers includes UV inhibitors and stabilisers that prevent fading and discolouration. Foiled finishes are particularly durable and tested to hold their colour for decades. Always choose a trusted supplier to ensure long-lasting colour.
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.
Schüco smart systems are designed to integrate with broader smart home platforms, allowing your door to work in concert with lighting, alarms, and heating. Our team can advise on compatibility with your existing setup.
Absolutely. Schüco offers an extensive palette of over 200 colours and finishes. You can choose from standard RAL colours, metallic effects, anodized finishes, or even realistic timber-effect foils. You can even specify different colours for the inside and outside of the door to match your interior décor and exterior facade perfectly.
Yes, options such as SafeGuard app and fingerprint access are available on certain smart door models, where supported. These features offer convenient and modern access control.
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.
Eurocell uPVC profiles are designed for exceptional longevity and are guaranteed for 10 years against discolouration, warping, and cracking. With proper care, you can expect them to perform beautifully for 20 years or more.
Maintenance is minimal. A simple wipe-down of the frames with a soft cloth and mild, non-abrasive detergent a few times a year is all that is needed to keep them looking pristine. The high-quality hardware may benefit from occasional lubrication.
Yes, Schüco doors are fully customisable. We can manufacture them to bespoke dimensions and offer a wide range of RAL colours, finishes, and panel designs to match your style and project requirements.
On the contrary, they provide excellent acoustic insulation. The robust, airtight seal and the use of double/triple glazing significantly reduce external noise pollution, creating a quieter, more peaceful indoor environment.
Many orangeries are built under Permitted Development rights. However, there are limits and conditions, especially for larger projects or homes in conservation areas. Our experts will guide you through this process.
A single handle controls both functions. The first turn opens the window in the tilt position. The second turn allows the window to swing open inwards.
Modern thermally broken aluminium windows can be very energy efficient. Thermal breaks, high-performance profiles, Low-E glazing, warm-edge spacers and quality seals all work together to reduce heat loss.
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.
Yes. Composite doors are available in traditional styles with woodgrain finishes that complement period properties. They offer the beauty of timber without the maintenance headaches.
Neither is universally better. Bi-fold doors are ideal if you want the widest possible physical opening and flexible ventilation. Sliding doors are ideal if you prioritise uninterrupted views, large glass panels, and a minimalist aesthetic. The right choice depends on your priorities and your property.
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.
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.
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.
