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.
Yes, modern aluminium glass roofs are highly energy efficient. Thermal breaks in the frame prevent cold bridging, and the double or triple glazing with Low-E coatings keeps heat in during winter and out during summer. Many systems exceed Part L requirements.
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.
Absolutely not. This is a common myth based on old, low-quality conservatories. Our lantern roofs use advanced technology, including thermally broken frames and specialist solar-control, low-emissivity (Low-E) glass. This means your room stays at a comfortable, usable temperature all year round.
They are generally considered a premium product, and the initial cost may be higher than uPVC. However, their durability, low maintenance, longevity, and the value they can add to a property often make them a worthwhile long-term investment.
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, typically. The significant brick walls and solid sections of the roof provide much better insulation than a fully glazed conservatory, making it easier and more cost-effective to heat all year round.
Aluminium windows command a higher initial investment than uPVC alternatives—typically 20-40% more depending on specification. However, aluminium’s extended lifespan (45+ years versus 20-25 for uPVC), minimal maintenance requirements, and positive contribution to property values frequently deliver superior long-term value.
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.
Absolutely. Modern French doors from Multitrades are equipped with high-security multipoint locking systems and robust frames, making them as secure as any modern door.
Yes. All our uPVC doors are A-rated for energy efficiency and come with high-performance weather seals.
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. 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.
Yes. Our conservatories are fitted with high-quality, multi-point locking systems as standard on both doors and windows. The robust frames and toughened safety glass used in all our installations provide a high level of security, giving you complete peace of mind.
They are generally considered a premium product, and the initial cost may be higher than uPVC. However, their durability, low maintenance, longevity, and the value they can add to a property often make them a worthwhile long-term investment.
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.
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.
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.
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.
Modern uPVC sash windows are designed to replicate the appearance of traditional timber sashes, with slim sightlines, deep bottom rails, and authentic detailing. They are a practical choice for period properties where maintaining architectural character is important, while offering the low-maintenance benefits of uPVC.
