Very professional, quick and tidy
The new patio doors and windows have completely transformed the back of our house. We love how much brighter it feels inside, and the smooth sliding doors make garden access so much easier. The Multitrades team did an excellent job — very professional, quick, and tidy throughout.

The slim frames look incredibly elegant and suit the building perfectly. The installation team was discreet, professional, and respectful of our home and neighbours throughout.

The new uPVC bay windows look absolutely beautiful
The new white uPVC bay windows look absolutely beautiful and have transformed the front of our Victorian house. They match the period style perfectly, but the warmth and silence inside are incredible. No more draughts or condensation. The installation team was professional and left everything spotless. Highly recommend.

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. Our conservatories are fitted with high-quality, multi-point locking systems as standard on both doors and windows. The robust frames and toughened safety glass used in all our installations provide a high level of security, giving you complete peace of mind.
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.
Sliding patio doors are usually made of two large glass panels, which open by sliding one panel behind the other. Sliding doors provide easy access to gardens and patios.
Yes. The high-density foam core provides excellent thermal insulation, significantly reducing heat loss. Many composite doors achieve U-values as low as 1.1 W/m²K.
Yes. Composite doors are available in traditional styles with woodgrain finishes that complement period properties. They offer the beauty of timber without the maintenance headaches.
Absolutely. While “Brilliant White” remains a classic choice, we offer a wide range ofRAL colours and woodgrain foils. Our most popular contemporary options include Anthracite Grey and Black, while our wood-effect finishes (like Irish Oak) provide the look of real timber without the maintenance.
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.
Yes. Schüco doors can be equipped with biometric, keypad, or smartphone access systems for modern convenience.
Generally, yes. While aluminium is very strong, uPVC is a natural insulator. Our multi-chambered uPVC profiles create a thermal barrier that prevents heat from escaping, often achieving higher energy ratings (A or A+) more cost-effectively than aluminium frames.
Our manufacturing capabilities encompass over 150 RAL colours with finishes including matte, satin, gloss, textured, and metallic effects. Wood-effect finishes convincingly replicate timber aesthetics without associated maintenance burdens. Dual-colour options allow different interior and exterior finishes—perhaps anthracite grey externally with white internally to complement interior décor.
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.
Many orangeries are built under Permitted Development rights. However, there are limits and conditions, especially for larger projects or homes in conservation areas. Our experts will guide you through this process.
Bi-fold doors can create a very wide open aperture because the panels fold away. Sliding doors can accommodate very large individual glass panels but usually leave part of the opening glazed. The best solution depends on whether you prioritise a fully open wall or expansive uninterrupted glazing.
Absolutely. In many ways they are more secure than traditional doors. There are no external key cylinders to pick or snap, access is encrypted, and you can monitor all entry events. Our Schüco systems achieve RC2 security ratings, offering robust protection against forced entry.
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.
Yes. Fingerprint systems like Schüco Fingerprint Easy support up to 20 users. With smartphone-based systems, you can grant access to family members, trusted friends, or service providers, with the ability to set permanent, temporary, or scheduled permissions.
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.
Because every door is made to measure with choices of size, configuration, smart features, finishes, and glazing, the price varies. We recommend a free, no-obligation consultation where we can understand your requirements and provide a detailed, bespoke quotation tailored to your property.
Absolutely. All our glass is safety-toughened as standard. Our frames and locking systems are designed and tested for maximum strength and security.
Yes. Not only do they reduce your home’s energy consumption (lowering your carbon footprint), but modern uPVC is also fully recyclable. At Multitrades Windows & Doors, we are committed to sustainable practices.
