The performance of the new windows is in a different league
The black Schüco sash windows have completely transformed our Barnet home. They look stunning against the brickwork and retain the traditional sash character, but the performance is in a different league. The house is warmer, quieter, and the quality is outstanding. The installation team was respectful of our period property and left everything spotless. Highly recommended.

Double Glazed Windows
This is to confirm that Multitrades recently installed double glazed windows and a door to my flat that I was updating in preparation to renting out. They did an excellent job. They were Professional, clean and efficient.
Just as important, their price was fair and reasonable. So impressed am I with the quality of their work, that I will use them again in the future when I update my permanent home. In addition, I would not hesitate to recommend them to my Family and Friend as I was so impressed with the work they did for me.

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. Modern aluminium sliding doors incorporate thermal breaks, double or triple glazing and advanced weather seals, vastly outperforming older aluminium or timber patio doors. U-values can be as low as 1.2 W/m²K or better, meeting and exceeding building regulations.
We provide a comprehensive guarantee that covers both the Schüco product and our installation workmanship. Full details will be provided with your quotation.
No. The advanced thermal break technology ensures the interior frame stays close to room temperature, eliminating the “cold feel” associated with old, non-thermally broken aluminium.
Absolutely. While known for modern designs, aluminium doors are incredibly versatile. We offer a range of classic colours (like heritage greens and greys) and even wood-effect finishes. The slim sightlines can be designed to complement traditional architecture, offering improved performance without compromising character.
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.
It depends on your priorities. Aluminium is often preferred for its slim sightlines, strength, and modern aesthetic, while uPVC is a strong, cost-effective choice for a wide range of properties. Aluminium is typically chosen when design and large glazing are the primary considerations.
Yes, we provide a full supply-and-installation service across London, Hertfordshire and surrounding areas. We also offer supply-only for trade clients who wish to install themselves.
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.
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.
Yes. The solid, rigid construction of a composite door resists flexing and forced entry far better than uPVC. Combined with multi-point locking systems, they offer significantly enhanced security.
While the initial investment can be comparable to high-end timber, uPVC sash windows offer significant long-term savings. You will save thousands of pounds over their lifespan on maintenance, repainting, and energy bills.
We provide a comprehensive guarantee that covers both the Schüco product and our installation workmanship. Full details will be provided with your quotation.
Absolutely. We provide 10-year product guarantees and a comprehensive installation warranty.
Bi-Fold Doors are normally suitable for large openings, giving you a way to effectively remove a wall and bring light into your home.
-
uPVC is a cost-effective, low-maintenance, and thermally efficient option, great for a classic look and excellent insulation.
-
Aluminium offers a sleeker, more modern appearance with slimmer frames for maximum light. It is incredibly strong, durable, and low-maintenance, ideal for larger, more contemporary designs.
Our team can guide you on the best material for your home, budget, and vision.
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.
Yes, we manufacture and supply high-quality uPVC Tilt & Turn Windows, which offer excellent thermal performance, low maintenance and great value.
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.
Absolutely not. This is a common myth based on old, low-quality conservatories. Our lantern roofs use advanced technology, including thermally broken frames and specialist solar-control, low-emissivity (Low-E) glass. This means your room stays at a comfortable, usable temperature all year round.
They are designed with modern security in mind, featuring multi-point locking systems. The tilt position also allows for secure ventilation.
