The skylights have transformed our kitchen
Getting rid of those old yellow PVC panels was the best decision we made. The skylights have transformed our kitchen from dark and depressing to bright and airy. The installation team was tidy and professional throughout.

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.
Our high-performance glass and thermally broken frames are specifically designed to combat this. We can specify glass with appropriate Solar Factor (g-values) and U-values to keep your room comfortable year-round, reducing both solar gain and heat loss.
Beyond classic white, we offer a extensive palette of colours, including Chartwell Green, Anthracite Grey, and Black, as well as dual-colour options (e.g., white on the inside, a colour on the outside).
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.
Maintenance is minimal. A simple wipe-down of the frames with a soft cloth and mild, non-abrasive detergent a few times a year is all that is needed to keep them looking pristine. The high-quality hardware may benefit from occasional lubrication.
Schüco Bi-Fold doors offer balance with style security, elegance and durability. Schüco smooth-running, stainless steel roller system allows you to move vents up to 3m in height and 100kg in weight effortlessly.
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.
The price varies significantly based on size, configuration, material (aluminium vs. uPVC), and glazing choice. A small uPVC 2-panel kitchen window will be a fraction of the cost of a large 4-panel aluminium system. We offer competitive pricing and will provide a precise, no-obligation quote based on your specifications.
Modern thermally broken aluminium windows can be very energy efficient. Thermal breaks, high-performance profiles, Low-E glazing, warm-edge spacers and quality seals all work together to reduce heat loss.
Yes. Modern woodgrain-effect uPVC uses advanced foiling techniques to create an authentic timber texture and appearance. Finishes like English Oak, Golden Oak, and Irish Oak are virtually indistinguishable from real wood.
Bi-Fold Doors help light to open up spaces and brighten up your home. This generally makes your home look more desirable which can potenitally add value if you ever choose to sale. Having easy access to a lovely garden or patio area is also a selling point that buyers like to see.
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.
Modern thermally broken aluminium windows can be very energy efficient. Thermal breaks, high-performance profiles, Low-E glazing, warm-edge spacers and quality seals all work together to reduce heat loss.
Yes. Schüco Bi‑Fold Doors are widely used in restaurants, shops, offices and hotels. They are built to withstand high‑traffic use, offer excellent security, and provide the flexibility to open up entire storefronts or partition walls as needed.
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.
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.
Lead times vary by design and specifications, but typically range from 4–8 weeks including installation.
Eurocell uPVC profiles are designed for exceptional longevity and are guaranteed for 10 years against discolouration, warping, and cracking. With proper care, you can expect them to perform beautifully for 20 years or more.
Yes. Modern uPVC includes heritage styles like flush sash, sliding sash, and woodgrain finishes specifically designed for period homes. These windows replicate traditional timber aesthetics while offering modern energy efficiency, security, and low maintenance.
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.
Generally, yes. Three panes and two insulating cavities usually reduce heat loss more than two panes and one cavity. However, the actual difference depends on the complete window system – frame, glazing specification, spacers, seals and installation – not just the number of panes.
