Customer Reviews
The new arched windows are absolutely stunning.
The new arched windows are absolutely stunning. They match the original shape perfectly and look just like traditional timber, but the warmth and quiet are on another level. No more draughts or condensation, and the house looks beautiful from the street. The installation team was meticulous, respectful of our period property, and left everything spotless. Highly recommended.

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.
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.
Yes. Schüco doors can be equipped with biometric, keypad, or smartphone access systems for modern convenience.
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.
We can supply with double or triple glazing, with options for self-cleaning glass, solar control, acoustic insulation, or decorative stained glass to match your home’s style.
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. Modern Schüco bi‑fold doors incorporate thermal break technology and can be fitted with double or triple glazing to achieve low U‑values. They meet and often exceed UK Building Regulations for energy efficiency, helping reduce heat loss and lower energy bills.
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.
Both our aluminium and uPVC bi-fold windows are incredibly low-maintenance. The frames simply need an occasional wipe with soapy water to keep them clean. The moving track and hinges should be kept free of debris and lightly lubricated annually to ensure years of smooth, flawless operation.
The installation itself is surprisingly fast. Once any preparatory work on your flat roof is complete, our specialist team can often install the lantern roof in just 1-2 days.
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.
The timeline can vary depending on the complexity and size of your order. During your initial consultation, we will provide you with an estimated timeline from survey to final installation. Because we control the entire process, we can often offer more reliable and efficient lead times.
They are dual-function windows that can either tilt inward from the top for secure ventilation or open fully inward from the side for maximum airflow and easy cleaning.
With modern, acoustically optimised double glazing, the sound of rain is significantly dampened and is often described as a gentle, soothing patter rather than a loud noise.
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.
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.
Our roofs are engineered with a sophisticated, integrated drainage system and high-performance seals. Combined with our expert installation, this ensures a completely watertight structure.
Yes. The inward-opening “turn” function allows you to easily reach and clean the outside pane of glass from within your home
Bi-fold doors can create a very wide open aperture because the panels fold away. Sliding doors can accommodate very large individual glass panels but usually leave part of the opening glazed. The best solution depends on whether you prioritise a fully open wall or expansive uninterrupted glazing.
No, they are very low maintenance. An occasional clean with warm soapy water is all that is usually needed to keep frames looking their best. They do not require painting or special treatments like timber windows.
Some extensions may qualify as permitted development, but this depends on factors such as dimensions, location and property type. Always check with your local planning authority and consult a building professional.
