Frequently asked questions
Yes. Modern uPVC windows benefit from significant advances in profile design, glazing technology, thermal insulation, and security. They typically offer better energy efficiency, improved weather resistance, and enhanced security compared with older uPVC windows. The choice of colours and finishes is also far wider today.
Flush-fit windows have a sash that closes level with the outer frame, creating a smooth, continuous surface. This mimics the appearance of traditional timber joinery and suits both period and contemporary properties. They are a popular alternative to standard casement windows for homeowners seeking a more refined look.
Yes. Tilt and turn windows are particularly well-suited to upper floors and apartments. The tilt function provides secure ventilation without a large opening, and the turn function allows full access for cleaning from inside. They are also a safer option for homes with young children.
Modern uPVC sash windows are designed to replicate the appearance of traditional timber sashes, with slim sightlines, deep bottom rails, and authentic detailing. They are a practical choice for period properties where maintaining architectural character is important, while offering the low-maintenance benefits of uPVC.
Modern uPVC windows can achieve high energy ratings through multi-chambered profiles, double or triple glazing, Low-E glass, and warm-edge spacers. Actual performance depends on the specific specification, the property, and the quality of installation.
Triple glazing offers superior thermal and acoustic performance compared with double glazing. It’s worth considering for noisy locations, homes aiming for maximum energy efficiency, or properties with large glazed areas. However, it isn’t necessary for every property — a well-specified double-glazed window is more than adequate for many homes.
Modern uPVC windows can incorporate multi-point locking, high-security handles, reinforced frames, and laminated or toughened glass. PAS 24 certification provides independent assurance of enhanced security. No window is completely burglar-proof, but a well-specified modern uPVC window offers a high level of protection.
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.
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.
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.
Flush-fit windows have a sash that closes level with the outer frame, creating a smooth, continuous surface. This mimics the appearance of traditional timber joinery and suits both period and contemporary properties. They are a popular alternative to standard casement windows for homeowners seeking a more refined look.
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.
Yes. You can fully customise the look, colour, glazing, and accessories to match your home’s style.
They are designed with modern security in mind, featuring multi-point locking systems. The tilt position also allows for secure ventilation.
Modern uPVC sash windows are designed to replicate the appearance of traditional timber sashes, with slim sightlines, deep bottom rails, and authentic detailing. They are a practical choice for period properties where maintaining architectural character is important, while offering the low-maintenance benefits of uPVC.
Remarkably little. Occasional cleaning with mild soapy water removes accumulated environmental residue. Hardware may benefit from silicone lubrication every few years. There’s no painting, staining, or treatment required to maintain appearance or weather resistance.
Triple glazing generally raises the internal surface temperature of the glass, which can reduce the risk of condensation forming on the pane. However, condensation is also affected by indoor humidity, ventilation and installation quality.
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.
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.
Maintenance is minimal. A simple wipe-down of the frames with a soft cloth and mild, non-abrasive detergent a few times a year is all that is needed to keep them looking pristine. The high-quality hardware may benefit from occasional lubrication.
Schüco Bi‑Fold Doors are a range of aluminium folding door systems manufactured by Schüco International, a leading German brand. They are designed to concertina to one or both sides, opening up large apertures with slim frames and high‑performance glazing.
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.
Yes. Tilt and turn windows are particularly well-suited to upper floors and apartments. The tilt function provides secure ventilation without a large opening, and the turn function allows full access for cleaning from inside. They are also a safer option for homes with young children.
The timeline varies depending on the size and complexity of the project. Typically, from initial consultation to completion, the process takes between 6 to 12 weeks. The on-site installation itself usually takes 1-3 weeks, carried out by our professional fitting teams with minimal disruption.
Bi-fold doors can create a very wide open aperture because the panels fold away. Sliding doors can accommodate very large individual glass panels but usually leave part of the opening glazed. The best solution depends on whether you prioritise a fully open wall or expansive uninterrupted glazing.
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.
Yes, we manufacture and supply high-quality uPVC Tilt & Turn Windows, which offer excellent thermal performance, low maintenance and great value.
Yes. With double glazing, weather seals, and thermally efficient materials (uPVC or thermally broken aluminium), our French doors significantly reduce heat loss and draughts, helping to lower your energy bills.
