Now it is bright, warm, and a joy to spend time in
The lean-to glass roof has completely transformed our kitchen extension. It’s now bright, warm, and a joy to spend time in, even on gloomy London days. The team removed the old polycarbonate roof with no fuss and installed the new glass roof beautifully. 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.
They eliminate several common vulnerabilities. Without a visible key cylinder, lock snapping, bumping, and picking are no longer threats. Electronic access logs and encryption add layers of security that a purely mechanical lock cannot provide.
Not with modern technology. This was a common problem with old polycarbonate or basic glass. We use high-performance solar control and thermally efficient glass to ensure your room remains at a comfortable temperature all year round.
Security is a core principle of Schüco engineering. All systems feature multi-point locking mechanisms as standard, along with integrated finger-trap protection and anti-lift devices on sliding doors. The inherent strength of the aluminium profile itself makes it extremely resistant to forced entry, and many systems meet stringent security standards like PAS 24.
Schüco is a premium brand, and its price reflects its superior quality, performance, and longevity. While the initial outlay is higher than standard windows, they represent a long-term investment that adds significant value to your property, reduces energy costs, and enhances your quality of life.
Not at all! Our uPVC and aluminium windows simply require an occasional wipe down with a damp, soapy cloth to keep them looking like new.
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.
Modern uPVC windows can incorporate multi-point locking, high-security handles, reinforced frames, and laminated or toughened glass. PAS 24 certification provides independent assurance of enhanced security. No window is completely burglar-proof, but a well-specified modern uPVC window offers a high level of protection.
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.
Schüco is a premium brand, and its price reflects its superior quality, performance, and longevity. While the initial outlay is higher than standard windows, they represent a long-term investment that adds significant value to your property, reduces energy costs, and enhances your quality of life.
Schüco Bi‑Fold Doors are a range of aluminium folding door systems manufactured by Schüco International, a leading German brand. They are designed to concertina to one or both sides, opening up large apertures with slim frames and high‑performance glazing.
The majority of windows can be installed from the outside of a property, but sometimes our contractors may need to come inside your property to install the windows.
You won’t be locked out. Depending on your configuration, you can use a registered fingerprint, a backup keypad, or a mechanical override that can be accessed securely. We will ensure you have a reliable backup method during the design consultation.
A high-resolution area sensor embedded in the handle reads the unique characteristics of your fingerprint. It authenticates you in a fraction of a second and signals the electronic lock to release. It is weather-resistant and works reliably even with slightly damp or dirty fingers.
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.
Yes. Both Schüco SafeGuard and BlueCon allow you to unlock your door via a dedicated app on your smartphone. You can do this when you’re near the door or, with an internet connection, from anywhere in the world.
Depending on how they’re installed, made and cared for, double glazing windows can last between 10-50 years. They should last for at least 20 years minimum.
Not with modern technology. This was a common problem with old polycarbonate or basic glass. We use high-performance solar control and thermally efficient glass to ensure your room remains at a comfortable temperature all year round.
A popular combination is a lantern glass roof over the dining or island area and aluminium bi-fold or sliding doors opening to the garden. This floods the space with light from above and the rear, creating a bright, social heart of the home.
Absolutely. With slim profiles, a vast range of colours (including anthracite grey, black, and Chartwell Green), and authentic woodgrain finishes, modern uPVC windows are at the forefront of contemporary home design. They are featured in new builds, renovations, and even conservation areas across the UK.
Yes, Schüco doors are fully customisable. We can manufacture them to bespoke dimensions and offer a wide range of RAL colours, finishes, and panel designs to match your style and project requirements.
