The Schüco windows are in a league of their own. Our home is noticeably warmer, quieter, and looks stunning from the street. The slim frames let in so much more light than our old uPVC windows.

Frequently asked questions
Consider replacing your front door when you notice persistent draughts, difficulty opening or closing, rot or warping, damaged seals, outdated locks, or if the door no longer suits your property’s appearance. A professional assessment can help determine whether repair or replacement is the better option.
For many homeowners, yes. A modern replacement can improve thermal insulation, security, kerb appeal, and reduce maintenance requirements. The long-term benefits often outweigh the initial investment.
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.
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.
A modern replacement door with good insulation, effective seals, and quality glazing can reduce heat loss through the entrance, potentially lowering heating demand. Actual performance depends on the specific door system and installation.
Traditional panelled doors, part-glazed doors with decorative glass, and modern doors designed to replicate classic timber styles are often suitable for traditional properties.
Smart front doors combine high-performance door construction with electronic, biometric, or wireless technology to control locking and unlocking. They can be operated via smartphone apps, fingerprints, or remote access systems.
Yes, options such as SafeGuard app and fingerprint access are available on certain smart door models, where supported. These features offer convenient and modern access control.
This is a common misconception based on old technology. Modern Schüco aluminium windows feature a sophisticated ‘thermal break’ – a polyamide insulator that separates the inner and outer frames. This completely stops thermal transfer, making the frames warm to the touch and preventing internal condensation.
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.
For many homeowners, yes. A modern replacement can improve thermal insulation, security, kerb appeal, and reduce maintenance requirements. The long-term benefits often outweigh the initial investment.
Absolutely. Modern French doors from Multitrades are equipped with high-security multipoint locking systems and robust frames, making them as secure as any modern door.
A thermal roof (or solid roof) is an advanced alternative to traditional polycarbonate panels. It is insulated like a regular house roof, making the conservatory cooler in summer and warmer in winter. It’s an excellent choice if you plan to use the room as a full-time living space, like a kitchen or lounge.
Lead times vary, but we will always provide you with a clear timeline during your quotation.
Schüco is one of the world’s leading brands for window and façade technology, known for its German engineering, quality, and performance. Choosing a Schüco system from an approved partner provides confidence in both the product and the installation.
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.
They are ideal. Children can gain entry with a simple fingerprint without the responsibility of carrying a key. You can let them in remotely after school, and you always know who has come and gone.
A single handle controls both functions. The first turn opens the window in the tilt position. The second turn allows the window to swing open inwards.
We use either toughened or laminated safety glass as standard. We also offer a range of performance glasses, including self-cleaning glass to reduce maintenance, solar control glass to minimise heat gain, and low-e coated glass for superior thermal insulation.
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.
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.
Not if it’s designed and built correctly. Modern conservatories with energy-efficient double glazing, thermal breaks in the frames, and options like thermal roof systems or solar control glass are designed for year-round comfort. We can also integrate ventilation and blinds to perfectly manage the temperature.
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.
Absolutely. This is one of the key benefits of an orangery. Its solid structure and integrated feel make it perfect for use as a kitchen, dining room, main lounge, or even a home office.
Absolutely. While they have a modern feel, their clean lines can beautifully complement period properties, especially when finished in colours like heritage grey or authentic wood grains. They offer a sympathetic yet contemporary upgrade.
Bi-Fold Doors are normally suitable for large openings, giving you a way to effectively remove a wall and bring light into your home.
Yes. The inward-opening “turn” function allows you to easily reach and clean the outside pane of glass from within your home
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.
