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.
Absolutely. We specialise in bespoke conservatories. Whether you live in a period property or a modern home, we design and manufacture your conservatory to complement its existing architecture. We offer a wide range of colours and finishes in both uPVC and aluminium to ensure a perfect match.
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.
We offer double and triple glazing, solar control, self-cleaning, toughened, laminated, Low-E, privacy and acoustic glass. We will specify the best combination for your project.
Yes. Schüco doors can be equipped with biometric, keypad, or smartphone access systems for modern convenience.
Modern uPVC windows are incredibly durable. When manufactured and installed to our high standards, you can expect them to last between 20 and 35 years. Because they are resistant to corrosion and moisture, they won’t warp or rot like timber.
Not at all! Our uPVC and aluminium windows simply require an occasional wipe down with a damp, soapy cloth to keep them looking like new.
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.
Yes. Schüco Bi‑Fold Doors are widely used in restaurants, shops, offices and hotels. They are built to withstand high‑traffic use, offer excellent security, and provide the flexibility to open up entire storefronts or partition walls as needed.
Lead times can vary depending on the complexity of the project and current material availability. However, as a manufacturer and installer, we have direct control over the supply chain. After your initial consultation and survey, we will provide you with a clear and accurate timeline for your specific project.
The primary difference is aesthetic. On a flush fit window, the opening sash sits perfectly level with the outer frame, creating a flat, smooth surface. A standard casement window has a ‘lipped’ sash that overlaps the frame when closed.
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. Privacy is one of the most common requests. We offer a wide variety of glazing options to suit any room. For bathrooms, ensuites, or rooms requiring privacy, we recommend options like frosted glass, reeded glass, or acid-etched glass. These styles obscure the view while still allowing beautiful, diffused light to flow through your home, maintaining the open and airy feel.
Yes. Bi-fold and sliding doors can improve access, daylight and the relationship between indoor and outdoor spaces, subject to the design and structural requirements.
Yes, this is one of their greatest strengths. The structural rigidity of aluminium allows it to support very large, heavy glazing units, making it the ideal choice for expansive picture windows and glazed façades.
Yes, we manufacture and supply high-quality uPVC Tilt & Turn Windows, which offer excellent thermal performance, low maintenance and great value.
The main difference between patio doors and french doors is the way they open. Patio doors slide along a track and open to the side, whereas french doors open outwards. Patio doors are more modern in appearance and therefore best suited to a modern contemporary property, whereas french doors lend themselves to more period and heritage properties.
Patio doors offer better ease of use, provide better security and space-saving opportunities. Patio doors use a glass pack and insulated frames to offer better energy efficiency than the traditional French doors. Patio doors are also more modern in appearance and therefore better suited to a modern, contemporary property.
Yes. New windows improve kerb appeal, energy efficiency, and security — all factors that can enhance a property’s market value. FENSA certification also provides documentation that buyers often look for.
Schüco sliding doors are made from aluminium, a natural raw material that is highly durable.
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.
