Customer Reviews
The bi-fold door has completely opened up our extension
The bi-fold door has completely opened up our extension. It folds back effortlessly, and we can now walk straight onto the patio. The team was professional, and the installation was completed in just one day. Worth every penny.
Mr M

The difference in comfort is night and day
You can barely tell they aren’t the original timber sashes, but the difference in comfort is night and day. The flat is warmer, quieter, and we finally feel secure. The team was respectful of our period home and left everything spotless.

You would hardly know these aren’t the original timber sashes
You would hardly know these aren’t the original timber sashes. They look beautiful and authentic, but the difference in warmth and noise is remarkable.

Frequently asked questions
They are dual-function windows that can either tilt inward from the top for secure ventilation or open fully inward from the side for maximum airflow and easy cleaning.
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.
Yes, we manufacture and supply high-quality uPVC Tilt & Turn Windows, which offer excellent thermal performance, low maintenance and great value.
Absolutely. We specialise in slimline aluminium Tilt & Turn Windows, perfect for achieving a modern, contemporary look with maximum glass area.
Yes, they are highly energy-efficient. With modern frames and advanced double or triple glazing, they can significantly reduce heat loss from your home.
They are designed with modern security in mind, featuring multi-point locking systems. The tilt position also allows for secure ventilation.
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.
Yes. The inward-opening “turn” function allows you to easily reach and clean the outside pane of glass from within your home
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. 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.
Both materials can look stunning. Aluminium offers ultra-slim frames favoured in minimalist designs, while premium uPVC now offers slim profiles and a vast range of colours and finishes that rival aluminium. The choice often comes down to budget and specific design preferences.
Absolutely. Every door set we produce is made to measure. You can tailor the number of panels, opening configuration, threshold style, handle design, glass type, and frame colour. We manufacture bespoke solutions for both residential and commercial projects.
Yes. All our uPVC doors are A-rated for energy efficiency and come with high-performance weather seals.
Yes, roof lanterns are specifically designed for flat roof installations. They sit on a purpose-built upstand or kerb and are fully weatherproof. We engineer every lantern to suit the roof structure and pitch exactly.
Aluminium doors offer superior strength with much slimmer frames, allowing for larger glass panels and more natural light. They are more durable and weather-resistant than uPVC, require far less maintenance than timber, and offer a more contemporary, high-end aesthetic. Their longevity and thermal performance with modern thermal breaks also make them a cost-effective long-term investment.
A standard installation is usually completed within half a day by our professional teams, ensuring a swift and hassle-free process.
Schüco smart systems are designed to integrate with broader smart home platforms, allowing your door to work in concert with lighting, alarms, and heating. Our team can advise on compatibility with your existing setup.
Absolutely. Schüco offers an extensive colour palette for aluminium windows & doors products, including custom RAL colours for aluminium systems to perfectly match your vision.
Yes. Unlike uPVC systems where damage often necessitates full replacement, aluminium windows can typically be repaired. Individual components—glazing units, hardware, gaskets—are replaceable, extending the already impressive service life still further.
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.
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.
All systems come with a highly secure locking mechanism, and we can install up to 8 panes of glass in our bi-fold doors.
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.
If you are replacing existing doors, you won’t usually need planning permission to add bi-fold doors. However, if you live in a conservation area you may need to get further information from your local council before going ahead. If you plan to build an extension and add bi-fold doors it’s always best to check local building regulations before you start work.
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.
Double glazing can potentially improve your home insulation up to 73% and reduce noise by as much as 70%.
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.
Quality uPVC from reputable manufacturers includes UV inhibitors and stabilisers that prevent fading and discolouration. Foiled finishes are particularly durable and tested to hold their colour for decades. Always choose a trusted supplier to ensure long-lasting colour.
