Frequently asked questions

Are modern uPVC windows better than older uPVC windows?2026-10-04T13:27:56+01:00

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.

What are flush-fit uPVC windows?2026-10-04T13:27:34+01:00

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.

Are uPVC tilt & turn windows suitable for upstairs rooms?2026-10-04T13:27:02+01:00

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.

Are uPVC sash windows suitable for period properties?2026-10-04T13:26:29+01:00

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.

Are modern uPVC windows energy efficient?2026-10-04T13:26:03+01:00

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.

Are triple-glazed uPVC windows worth considering?2026-10-04T13:24:24+01:00

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.

How secure are modern uPVC windows?2026-10-04T13:23:38+01:00

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.

What are Tilt & Turn Windows?2026-09-30T12:16:50+01:00

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.

Do large glass roofs make a home too hot in summer?2026-06-05T13:52:13+01:00

Not if the glass is correctly specified. Modern solar control glass, low-E coatings and thermally broken aluminium frames limit solar gain and maintain comfortable internal temperatures. Ventilation, such as opening skylights or sliding doors, helps regulate heat naturally.

Are lantern roofs prone to leaking?2025-10-23T15:18:16+01:00

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.

How long does a composite door last?2025-09-18T20:51:23+01:00

With proper care, a high-quality composite door from Multitrades has a life expectancy of over 30 years, maintaining its performance and appearance throughout.

How often should you change double glazing windows?2025-06-11T15:18:47+01:00

With an average lifespan of 20-35 years, double glazing windows are normally recommended to be no more than every 40 years, but this all depends on the conditions of the windows.

Are smart entrance doors more secure than traditional doors?2026-06-12T15:43:36+01:00

They eliminate several common vulnerabilities. Without a visible key cylinder, lock snapping, bumping, and picking are no longer threats. Electronic access logs and encryption add layers of security that a purely mechanical lock cannot provide.

Can aluminium windows be repaired if damaged?2026-04-08T14:26:28+01:00

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.

Are Crittall style doors high maintenance?2025-09-21T14:56:36+01:00

No, they are generally very low maintenance. The steel or aluminium frames are typically galvanised and powder-coated to protect against rust, corrosion, and fading. Routine upkeep usually only requires wiping the frames and glass clean with a damp cloth and soapy water periodically. Unlike wood, they do not require regular repainting.

Will Bi-Fold Doors Add Value to my Property?2025-06-11T15:18:47+01:00

Bi-Fold Doors help light to open up spaces and brighten up your home. This generally makes your home look more desirable which can potenitally add value if you ever choose to sale. Having easy access to a lovely garden or patio area is also a selling point that buyers like to see.

Do you offer a warranty?2025-11-09T15:41:05+00:00

Yes. We stand by the quality of our workmanship and materials. All our conservatories come with a comprehensive manufacturer’s and installation guarantee, giving you long-term protection and peace of mind. Specific warranty details will be provided with your quotation.

Is triple glazing more energy efficient than double glazing?2026-09-15T14:13:02+01:00

Generally, yes. Three panes and two insulating cavities usually reduce heat loss more than two panes and one cavity. However, the actual difference depends on the complete window system – frame, glazing specification, spacers, seals and installation – not just the number of panes.

Are your doors energy-rated?2025-07-16T15:28:56+01:00

Yes. All our uPVC doors are A-rated for energy efficiency and come with high-performance weather seals.

What is the difference between a uPVC and an Aluminium conservatory?2025-11-09T15:38:37+00:00
  • uPVC is a cost-effective, low-maintenance, and thermally efficient option, great for a classic look and excellent insulation.

  • Aluminium offers a sleeker, more modern appearance with slimmer frames for maximum light. It is incredibly strong, durable, and low-maintenance, ideal for larger, more contemporary designs.

Our team can guide you on the best material for your home, budget, and vision.

How long do uPVC windows typically last?2026-10-04T13:23:58+01:00

Modern uPVC windows are incredibly durable. When manufactured and installed to our high standards, you can expect them to lastbetween 20 and 35 years. Because they are resistant to corrosion and moisture, they won’t warp or rot like timber.

Are triple-glazed uPVC windows worth considering?2026-10-04T13:24:24+01:00

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.

Can Tilt & Turn Windows be double or triple glazed?2026-09-30T12:12:26+01:00

Yes, they can be specified with either double or triple glazing, depending on your thermal, acoustic and budget requirements.

Can I customise my composite door?2026-07-14T16:54:51+01:00

Absolutely. Composite doors are available in a huge range of colours, finishes, glazing options and hardware styles. Whether you prefer traditional or contemporary, there’s a door to match your taste.

Can you match the conservatory to my house’s style?2025-11-09T15:39:57+00:00

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.

Are Schüco smart doors suitable for family homes?2026-06-12T15:44:47+01:00

They are ideal. Children can gain entry with a simple fingerprint without the responsibility of carrying a key. You can let them in remotely after school, and you always know who has come and gone.

Can you install a lantern roof on an existing property?2025-10-23T15:18:46+01:00

Absolutely. We regularly install lantern roofs on both new builds and existing homes as part of renovation and extension projects.

How long does it take to manufacture and install a Schüco entrance door?2025-07-11T14:45:05+01:00

Lead times vary by design and specifications, but typically range from 4–8 weeks including installation.
