Frequently asked questions
Minimal maintenance is required. A simple clean with mild soapy water a couple of times a year is all that’s needed to keep the frames and glass looking new. There is no need for sanding, painting, or sealing.
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.
Yes. Aluminium’s strength makes it the ideal material for large-span openings. We can manufacture and install expansive sliding and bifold door systems with minimal supporting框架, creating breath-taking, seamless transitions to your garden or terrace.
On the contrary, they provide excellent acoustic insulation. The robust, airtight seal and the use of double/triple glazing significantly reduce external noise pollution, creating a quieter, more peaceful indoor environment.
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.
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.
A high-quality aluminium door system, like those from Schüco, can last 40-45 years or more with minimal care. The aluminium itself does not degrade, and the powder-coated finishes are designed to withstand decades of UK weather without fading, peeling, or corroding.
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.
On the contrary, they provide excellent acoustic insulation. The robust, airtight seal and the use of double/triple glazing significantly reduce external noise pollution, creating a quieter, more peaceful indoor environment.
Absolutely. We specialise in creating windows that complement your home’s architecture, from traditional sash windows for period properties to sleek, modern designs for contemporary builds.
Our aluminium and uPVC frames are virtually maintenance-free and just need an occasional wipe-down. For the glass, we highly recommend upgrading to self-cleaning glass, which uses a special coating to break down organic dirt and let rainwater wash it away, keeping your view clear for longer.
Modern, high-quality double or triple glazing provides excellent acoustic insulation. While you may hear a gentle sound during a heavy downpour (as you would with any window), it is a world away from the loud drumming associated with old polycarbonate roofs.
Double glazing can potentially improve your home insulation up to 73% and reduce noise by as much as 70%.
We provide a comprehensive guarantee that covers both the Schüco product and our installation workmanship. Full details will be provided with your quotation.
Absolutely. Our windows are engineered for security. With internal beading, multi-point locking mechanisms, and robust construction, they offer excellent protection for your home. We can also build them to PAS 24 and Secured by Design standards for enhanced security.
The primary difference is aesthetic. On a flush fit window, the opening sash sits perfectly level with the outer frame, creating a flat, smooth surface. A standard casement window has a ‘lipped’ sash that overlaps the frame when closed.
A glass roof is significantly quieter than a polycarbonate roof. The solid, insulated units muffle the sound of rain, creating a much more peaceful and usable space.
Absolutely. Our design service is all about replication and enhancement. We will carefully measure and assess your existing windows to ensure our new uPVC sashes are a perfect match in style, proportion, and detail.
The timeline varies but typically takes several weeks. This allows for manufacturing and careful scheduling. We will provide you with a clear timeline upon order.
Yes. Between the savings on your energy bills, increased home security, enhanced comfort, and added property value, double glazing offers one of the best returns on investment for any home improvement.
Yes. All our uPVC doors are A-rated for energy efficiency and come with high-performance weather seals.
Absolutely. Schüco offers an extensive colour palette for aluminium windows & doors products, including custom RAL colours for aluminium systems to perfectly match your vision.
Absolutely. We specialise in bespoke conservatories. Whether you live in a period property or a modern home, we design and manufacture your conservatory to complement its existing architecture. We offer a wide range of colours and finishes in both uPVC and aluminium to ensure a perfect match.
Yes. To meet building regulations and ensure adequate background ventilation, we can integrate almost invisible trickle vents into the window head.
Every door we provide is made-to-measure. Our process begins with a professional survey conducted by one of our experts. They will visit your home to take precise measurements of your existing opening and discuss all details on-site. This ensures your bespoke Crittall style door is manufactured to fit perfectly, eliminating any issues with irregular-sized openings.
With proper care, a high-quality composite door from Multitrades has a life expectancy of over 30 years, maintaining its performance and appearance throughout.
The primary difference is aesthetic. On a flush fit window, the opening sash sits perfectly level with the outer frame, creating a flat, smooth surface. A standard casement window has a ‘lipped’ sash that overlaps the frame when closed.
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.
