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.
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.
A high-quality aluminium door system, like those from Schüco, can last 40-45 years or more with minimal care. The aluminium itself does not degrade, and the powder-coated finishes are designed to withstand decades of UK weather without fading, peeling, or corroding.
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.
Each material has its strengths. Composite doors offer a good balance of security, thermal performance, and traditional aesthetics. Aluminium doors provide slim sightlines and a contemporary look. uPVC doors are practical, low-maintenance, and cost-effective. The best choice depends on your priorities and property style.
Sliding doors often provide cleaner, more uninterrupted views because they use large single panes with minimal vertical framing. Bi-fold doors also offer excellent views but have more frame divisions due to their hinged panels.
Absolutely. We provide 10-year product guarantees and a comprehensive installation warranty.
Yes. Aluminium’s strength makes it the ideal material for large-span openings. We can manufacture and install expansive sliding and bifold door systems with minimal supporting框架, creating breath-taking, seamless transitions to your garden or terrace.
The cost of Tilt & Turn Windows varies depending on several factors, including window size, the number of windows required, frame material (uPVC or aluminium), glazing specification, colour/finish, hardware options and installation requirements. For an accurate price, we recommend requesting a free, no-obligation quote.
Yes, modern Crittall style doors are designed for efficiency. External doors typically feature double or even triple glazing and “thermally broken” frames (a layer of insulation between the internal and external frame) to prevent heat transfer. For security, external steel-framed versions often include reinforced glass and multi-point locking systems, making them highly robust.
Our aluminium and uPVC frames are virtually maintenance-free and just need an occasional wipe-down. For the glass, we highly recommend upgrading to self-cleaning glass, which uses a special coating to break down organic dirt and let rainwater wash it away, keeping your view clear for longer.
Each material has its strengths. Composite doors offer a good balance of security, thermal performance, and traditional aesthetics. Aluminium doors provide slim sightlines and a contemporary look. uPVC doors are practical, low-maintenance, and cost-effective. The best choice depends on your priorities and property style.
Yes, they are engineered to withstand the full range of UK weather. Robust aluminium frames, high-performance gaskets and precision welding ensure they remain watertight and airtight in driving rain, high winds and snow loads.
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.
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.
Lower is better. What counts as “good” depends on the project, the building regulations that apply and the whole-window figure (Uw) rather than the glass alone. Rather than chasing the lowest advertised number, ask for the whole-window performance of the specific system you are considering.
Absolutely. All our glass roofs are made to measure. We manufacture in Britain, so we can cater to unusual dimensions, specific pitch angles and non-standard shapes without compromise.
Lead times vary by design and specifications, but typically range from 4–8 weeks including installation.
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.
Absolutely. We stand behind the quality of our products and workmanship. All our windows come with comprehensive guarantees—ask our team for specific details on the 10-year guarantee on profiles and installation.
Yes. You can fully customise the look, colour, glazing, and accessories to match your home’s style.
