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.
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.
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.
Absolutely. While they have a modern feel, their clean lines can beautifully complement period properties, especially when finished in colours like heritage grey or authentic wood grains. They offer a sympathetic yet contemporary upgrade.
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.
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.
Yes, roof lanterns are specifically designed for flat roof installations. They sit on a purpose-built upstand or kerb and are fully weatherproof. We engineer every lantern to suit the roof structure and pitch exactly.
Absolutely. While known for modern designs, aluminium doors are incredibly versatile. We offer a range of classic colours (like heritage greens and greys) and even wood-effect finishes. The slim sightlines can be designed to complement traditional architecture, offering improved performance without compromising character.
Absolutely. In many ways they are more secure than traditional doors. There are no external key cylinders to pick or snap, access is encrypted, and you can monitor all entry events. Our Schüco systems achieve RC2 security ratings, offering robust protection against forced entry.
Yes. Modern thermally broken aluminium systems are designed to carry deeper, heavier glazed units while maintaining slim sightlines. The frame profile and system need to be specified appropriately for the weight and depth of the glazing.
Many lean-to glass roofs fall under “Permitted Development” rights, but this depends on the size, location, and your property type. We will advise you during the design process and can handle the application if required.
Glass offers far superior performance.
- Clarity: Glass provides a crystal-clear view and lets in more light.
- Longevity: Glass doesn’t discolour or turn brittle over time like plastic.
- Acoustics: Glass is much quieter in rain.
- Efficiency: Glass offers far better thermal insulation.
In most cases, no. Installing a roof lantern on an existing flat roof typically falls under “Permitted Development” rights. If it’s part of a new extension, it’s usually covered by the (often-permitted) extension plans. We can provide advice on this during our survey, but we always recommend checking with your local authority.
Absolutely. While “Brilliant White” remains a classic choice, we offer a wide range of RAL colours and woodgrain foils. Our most popular contemporary options include Anthracite Grey and Black, while our wood-effect finishes (like Irish Oak) provide the look of real timber without the maintenance.
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.
Schüco windows stand out due to superior German engineering that delivers tangible benefits:
-
Better Energy Efficiency: Advanced thermal breaks often meet Passive House standards, drastically reducing your energy bills.
-
Stronger Security: Integrated, multi-point locking systems are certified to the highest anti-burglary ratings for maximum peace of mind.
-
Sleeker Design & Durability: They offer remarkably slim sightlines for more glass and less frame, all while being built to last for decades with minimal maintenance.
-
Precision & Quality: Every component is engineered to work together flawlessly, ensuring smooth operation and long-term reliability that cheaper alternatives can’t match.
In short, you’re investing in proven performance, security, and comfort, not just a window.
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.
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.
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.
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.
