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.
Our high-performance glass and thermally broken frames are specifically designed to combat this. We can specify glass with appropriate Solar Factor (g-values) and U-values to keep your room comfortable year-round, reducing both solar gain and heat loss.
Yes. All our uPVC doors are A-rated for energy efficiency and come with high-performance weather seals.
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.
Modern, high-quality double or triple glazing provides excellent acoustic insulation. While you may hear a gentle sound during a heavy downpour (as you would with any window), it is a world away from the loud drumming associated with old polycarbonate roofs.
With proper installation and care, quality uPVC windows can last 20–30 years or more. Many manufacturers offer guarantees of 10 years or longer, reflecting the durability of modern materials and construction.
Schüco Bi-Fold doors offer balance with style security, elegance and durability. Schüco smooth-running, stainless steel roller system allows you to move vents up to 3m in height and 100kg in weight effortlessly.
We provide a comprehensive, insurance-backed guarantee covering the door slab, frame, hardware, and installation, giving you complete peace of mind. Please ask for full details during your consultation.
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.
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.
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.
Schüco is one of the world’s leading brands for window and façade technology, known for its German engineering, quality, and performance. Choosing a Schüco system from an approved partner provides confidence in both the product and the installation.
A solid, level base (like a concrete foundation or an existing patio) is essential. While we specialise in the supply and installation of the conservatory structure itself, we can project manage the entire build and work with trusted groundworkers to prepare the base for you.
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.
Schüco sliding doors are made from aluminium, a natural raw material that is highly durable.
Absolutely. Our windows are engineered for security. With internal beading, multi-point locking mechanisms, and robust construction, they offer excellent protection for your home. We can also build them to PAS 24 and Secured by Design standards for enhanced security.
Modern uPVC windows are incredibly durable. When manufactured and installed to our high standards, you can expect them to lastbetween 20 and 35 years. Because they are resistant to corrosion and moisture, they won’t warp or rot like timber.
The cost varies depending on the size, style, colour, glazing, and hardware options you choose. Because we manufacture them ourselves, we offer highly competitive pricing. Contact us for a free, detailed, and no-obligation quote tailored to your specific needs.
Schüco offer standard and bespoke aluminium glazing solutions, their range of products include windows, doors, facade glazing, blast and fire-resistant systems as well as purpose-designed glazing.
Lead times vary by design and specifications, but typically range from 4–8 weeks including installation.
Yes. Aluminium door systems are typically made to measure to suit the specific opening and design requirements of each property.
