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.
Yes. To meet building regulations and ensure adequate background ventilation, we can integrate almost invisible trickle vents into the window head.
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.
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.
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.
They are designed with modern security in mind, featuring multi-point locking systems. The tilt position also allows for secure ventilation.
Yes. Eurocell uPVC is a fully recyclable material, and the exceptional energy efficiency of the windows helps to reduce your carbon footprint by lowering heating costs.
Yes, they can be. While often associated with modern architecture, aluminium windows can provide a crisp, contemporary update to an older property. However, it’s essential to check planning and conservation rules, particularly for listed buildings.
Yes. All our uPVC doors are A-rated for energy efficiency and come with high-performance weather seals.
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.
Installation time varies depending on the door type, property construction, and any necessary adjustments. A straightforward replacement can often be completed within a day, while more complex installations may take longer. A professional installer can provide a more accurate timeframe after assessment.
Our flush fit windows are primarily crafted from advanced, multi-chambered uPVC. This material provides exceptional thermal efficiency, security, and durability, and is available in a huge range of smooth colours and highly realistic woodgrain finishes.
High-quality uPVC windows have a life expectancy of 30-35 years or more. They are incredibly durable and are backed by extensive guarantees, which we are proud to offer on our products and installation.
Not if the glass is correctly specified. Modern solar control glass, low-E coatings and thermally broken aluminium frames limit solar gain and maintain comfortable internal temperatures. Ventilation, such as opening skylights or sliding doors, helps regulate heat naturally.
Both are relatively low maintenance thanks to aluminium’s durability and weather resistance. Bi-fold doors have hinges and a folding mechanism that may require occasional cleaning and lubrication. Sliding doors have tracks and rollers that should be kept clean. Routine care keeps both operating smoothly.
Schüco sliding doors operate almost noiselessly in corrosion-free stainless steel tracks. The sliding unit runs in a single pane, with no unsightly vent protruding into the room. It’s even possible to combine up to six glazed frames depending on requirements.
Yes, they are an excellent choice for upstairs rooms due to their secure ventilation and the ease with which the external glass can be cleaned from inside.
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.
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.
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.
Yes. Modern uPVC windows benefit from significant advances in profile design, glazing technology, thermal insulation, and security. They typically offer better energy efficiency, improved weather resistance, and enhanced security compared with older uPVC windows. The choice of colours and finishes is also far wider today.
