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
Yes. Schüco doors can be equipped with biometric, keypad, or smartphone access systems for modern convenience.
Absolutely. While they are perfect for period properties, their clean, minimalist lines also make them a fantastic choice for modern and contemporary new-build homes, adding a touch of premium, architectural elegance.
Neither is universally better. Bi-fold doors are ideal if you want the widest possible physical opening and flexible ventilation. Sliding doors are ideal if you prioritise uninterrupted views, large glass panels, and a minimalist aesthetic. The right choice depends on your priorities and your property.
Yes. Builders, architects and developers can open a trade account with us. We offer supply-only on very competitive terms, complete with technical drawings, structural calculations and dedicated account management.
In most cases, no. Conservatories often fall under “Permitted Development Rights.” However, this is subject to certain limits and conditions (e.g., size, height, and location). As part of our service, Multitrades Windows & Doors will advise you on this and ensure your project is fully compliant with building regulations where required.
Yes, they can be. While often associated with modern architecture, aluminium windows can provide a crisp, contemporary update to an older property. However, it’s essential to check planning and conservation rules, particularly for listed buildings.
The installation itself is surprisingly fast. Once any preparatory work on your flat roof is complete, our specialist team can often install the lantern roof in just 1-2 days.
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.
Yes, they are engineered to withstand the full range of UK weather. Robust aluminium frames, high-performance gaskets and precision welding ensure they remain watertight and airtight in driving rain, high winds and snow loads.
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.
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.
Beyond classic white, we offer a extensive palette of colours, including Chartwell Green, Anthracite Grey, and Black, as well as dual-colour options (e.g., white on the inside, a colour on the outside).
A typical domestic installation can often be completed in a single day by our professional team. More complex or larger projects might take slightly longer. We always work cleanly and efficiently to minimise disruption, and we’ll provide a clear timeframe following your survey.
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.
Schüco sliding doors are made from aluminium, a natural raw material that is highly durable.
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.
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.
As we are the manufacturer and the installer, we offer a comprehensive, insurance-backed guarantee that covers both the product and the workmanship.
Yes. Schüco doors can be equipped with biometric, keypad, or smartphone access systems for modern convenience.
Yes, they are highly energy-efficient. With modern frames and advanced double or triple glazing, they can significantly reduce heat loss from your home.
