We were so impressed
We were so impressed with how authentic the new sash windows look. They’ve kept the character of our Victorian home but added all the modern benefits we needed. The house feels warmer, quieter, and much easier to maintain. The Multitrades team were professional, polite, and completed the work to a very high standard.

New Windows and Doors
I have nothing but praise for my new windows and doors supplied and fitted by Multitrades. From the initial showroom visit to the surveying and on to installation nothing was too much trouble.
The doors and windows themselves are top quality and have transformed the house. The fitting team let us know which area they would work day by day to minimise disruption and left the site clean and tidy. The house has a warmer feel to it and has attracted numerous comments from neighbours, one of whom I have passed on my recommendation. Friendly people to deal with, a good job done and all at a competitive price! Many thanks!

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 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.
Patio doors offer better ease of use, provide better security and space-saving opportunities. Patio doors use a glass pack and insulated frames to offer better energy efficiency than the traditional French doors. Patio doors are also more modern in appearance and therefore better suited to a modern, contemporary property.
We provide a comprehensive guarantee that covers both the Schüco product and our installation workmanship. Full details will be provided with your quotation.
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.
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.
The initial investment for aluminium doors is higher than for standard uPVC. However, they offer far greater longevity, a premium aesthetic, better performance, and require no maintenance costs (like repainting). Over their lifetime, they represent excellent value and can significantly enhance property value.
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.
They are generally considered a premium product, and the initial cost may be higher than uPVC. However, their durability, low maintenance, longevity, and the value they can add to a property often make them a worthwhile long-term investment.
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.
Modern composite doors with GRP skins are engineered to resist fading. The colour is impregnated into the material rather than painted on the surface, so it stays vibrant for much longer than painted alternatives.
A smart front door is an entrance door that incorporates electronic, biometric, or wireless technology to control locking. It can be opened by fingerprint, smartphone, or app, removing the need for traditional keys and allowing remote access management.
In most cases, no. Installing a roof lantern on an existing flat roof typically falls under “Permitted Development” rights. If it’s part of a new extension, it’s usually covered by the (often-permitted) extension plans. We can provide advice on this during our survey, but we always recommend checking with your local authority.
Our bespoke manufacturing process typically delivers within 4-6 weeks from final survey, though this varies with project complexity and current production scheduling. We provide firm lead time commitments during the quotation process.
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.
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.
Yes, modern aluminium doors are highly energy efficient. The key is the “thermal break” – a polyamide barrier inside the frame that separates the inner and outer aluminium, preventing heat loss. Combined with double or triple glazing filled with argon gas, our doors achieve excellent U-values (often as low as 0.8 W/m²K), meeting and exceeding current Building Regulations.
-
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.
Absolutely. We provide 10-year product guarantees and a comprehensive installation warranty.
Absolutely. Schüco offers an extensive colour palette for aluminium windows & doors products, including custom RAL colours for aluminium systems to perfectly match your vision.
Schüco systems are inherently secure thanks to multi‑point locking, anti‑lift devices, toughened glass and robust aluminium frames. When specified, they can meet PAS 24 and Secured by Design standards, providing a very high level of protection against intrusion.
