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
The majority of windows can be installed from the outside of a property, but sometimes our contractors may need to come inside your property to install the windows.
Yes. Modern uPVC includes heritage styles like flush sash, sliding sash, and woodgrain finishes specifically designed for period homes. These windows replicate traditional timber aesthetics while offering modern energy efficiency, security, and low maintenance.
Modern aluminium windows are highly energy-efficient. They incorporate thermal breaks—insulating sections within the frame—which, combined with high-performance glazing, provide excellent thermal performance.
Modern thermally broken aluminium windows can be very energy efficient. Thermal breaks, high-performance profiles, Low-E glazing, warm-edge spacers and quality seals all work together to reduce heat loss.
A solid, level base (like a concrete foundation or an existing patio) is essential. While we specialise in the supply and installation of the conservatory structure itself, we can project manage the entire build and work with trusted groundworkers to prepare the base for you.
Security is a core principle of Schüco engineering. All systems feature multi-point locking mechanisms as standard, along with integrated finger-trap protection and anti-lift devices on sliding doors. The inherent strength of the aluminium profile itself makes it extremely resistant to forced entry, and many systems meet stringent security standards like PAS 24.
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, 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.
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.
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.
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.
No, they are very low maintenance. An occasional clean with warm soapy water is all that is usually needed to keep frames looking their best. They do not require painting or special treatments like timber windows.
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. Schüco’s advanced modular systems, particularly those built on the AD UP platform, support barrier-free living. We can supply and install doors with a fully flush, zero-threshold threshold, creating a seamless transition between inside and out that is ideal for wheelchair users, pushchairs, and simply reducing trip hazards.
Combine large overhead glazing – like a lantern roof or flat skylight – with full-height aluminium sliding or bi-fold doors. Position the extension to capture the best orientation, choose open plan layouts, and specify slimline frames for minimal obstruction.
Not when installed correctly. The key is in the design and installation. Our lanterns are designed with effective drainage channels and we use high-quality seals. Combined with our expert installation, we guarantee a completely watertight finish.
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.
Absolutely. All our glass roofs are made to measure. We manufacture in Britain, so we can cater to unusual dimensions, specific pitch angles and non-standard shapes without compromise.
A solid, level base (like a concrete foundation or an existing patio) is essential. While we specialise in the supply and installation of the conservatory structure itself, we can project manage the entire build and work with trusted groundworkers to prepare the base for you.
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.
