Frequently asked questions

Are aluminium sliding doors secure?2026-09-18T10:30:24+01:00

Quality aluminium sliding doors can be specified with multi-point locking and robust hardware. Security features vary by product and configuration, so it is important to choose a reputable system and professional installation.

Are bi-fold doors suitable for UK homes?2026-09-18T10:26:37+01:00

Yes. Bi-fold doors are widely used in UK homes, particularly for extensions, kitchen-diners, and garden rooms. They are available in configurations suited to British weather conditions and building regulations.

Are bi-fold doors better than sliding doors?2026-09-18T10:25:22+01:00

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.

What is the difference between bi-fold and sliding doors?2026-09-18T10:24:54+01:00

Bi-fold doors are made of panels connected by hinges that fold and stack to the side. Sliding doors have large panels that slide horizontally behind or alongside one another. Bi-fold doors create a wider clear opening; sliding doors typically retain more glass in place.

Which is better for large openings, bi-fold or sliding doors?2026-09-18T10:24:32+01:00

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.

Do sliding doors provide better views than bi-fold doors?2026-09-18T10:24:07+01:00

Sliding doors often provide cleaner, more uninterrupted views because they use large single panes with minimal vertical framing. Bi-fold doors also offer excellent views but have more frame divisions due to their hinged panels.

Which is easier to maintain, bi-fold or sliding doors?2026-09-18T10:23:24+01:00

Both are relatively low maintenance thanks to aluminium’s durability and weather resistance. Bi-fold doors have hinges and a folding mechanism that may require occasional cleaning and lubrication. Sliding doors have tracks and rollers that should be kept clean. Routine care keeps both operating smoothly.

Can aluminium bi-fold and sliding doors be made to measure?2026-09-18T10:22:20+01:00

Yes. Aluminium door systems are typically made to measure to suit the specific opening and design requirements of each property.

Are aluminium windows energy efficient?2026-09-02T22:04:59+01:00

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.

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.

Can uPVC windows look like timber?2026-08-06T15:59:41+01:00

Yes. Modern woodgrain-effect uPVC uses advanced foiling techniques to create an authentic timber texture and appearance. Finishes like English Oak, Golden Oak, and Irish Oak are virtually indistinguishable from real wood.

Do coloured uPVC windows fade?2026-08-06T15:58:33+01:00

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.

What maintenance do Aluminium Doors require?2025-12-11T22:01:14+00:00

Minimal maintenance is required. A simple clean with mild soapy water a couple of times a year is all that’s needed to keep the frames and glass looking new. There is no need for sanding, painting, or sealing.

Are conservatories secure?2025-11-09T15:40:17+00:00

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.

Are modern uPVC windows still fashionable?2026-08-06T15:58:52+01:00

Absolutely. With slim profiles, a vast range of colours (including anthracite grey, black, and Chartwell Green), and authentic woodgrain finishes, modern uPVC windows are at the forefront of contemporary home design. They are featured in new builds, renovations, and even conservation areas across the UK.

Is a glass roof noisy when it rains?2025-11-09T14:07:29+00:00

With modern, acoustically optimised double glazing, the sound of rain is significantly dampened and is often described as a gentle, soothing patter rather than a loud noise.

How effective is double glazing windows?2025-06-11T15:18:47+01:00

Double glazing can potentially improve your home insulation up to 73% and reduce noise by as much as 70%.

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.

Are Schüco systems suitable for large openings?2026-05-18T15:58:40+01:00

Yes. Schüco profiles are engineered to span wide openings up to several metres in width, with individual panels capable of reaching heights of 3 metres or more. The robust aluminium frames and heavy‑duty running gear handle the extra weight of large panes of glass without distorting.

Do I need planning permission for a flat glass rooflight?2025-10-19T22:19:46+01:00

In most cases, rooflights fall under “Permitted Development” and do not require planning permission, provided they do not protrude more than 150mm from the roof plane. However, rules can differ in conservation areas or for listed buildings. We can advise you on this during our consultation.

Do you offer guarantees?2025-07-16T15:29:28+01:00

Absolutely. We provide 10-year product guarantees and a comprehensive installation warranty.

What is the best glazing option for a kitchen extension?2026-06-05T13:51:40+01:00

A popular combination is a lantern glass roof over the dining or island area and aluminium bi-fold or sliding doors opening to the garden. This floods the space with light from above and the rear, creating a bright, social heart of the home.

Are flush sash windows more modern?2026-08-06T15:59:41+01:00

Flush sash windows offer a sleek, contemporary look where the sash sits flush with the outer frame. They are particularly popular for traditional and heritage homes, as they replicate the clean lines of timber windows while providing modern performance.

What glass options do you offer?2025-10-08T21:57:20+01:00

We offer a full range of high-performance glazing options, including double or triple glazing with Low-E coatings, argon gas fills, and various tinted or obscured glass options for privacy.

What maintenance do Aluminium Doors require?2025-12-11T22:01:14+00:00

Minimal maintenance is required. A simple clean with mild soapy water a couple of times a year is all that’s needed to keep the frames and glass looking new. There is no need for sanding, painting, or sealing.

What is a smart front door?2026-06-12T15:47:52+01:00

A smart front door is an entrance door that incorporates electronic, biometric, or wireless technology to control locking. It can be opened by fingerprint, smartphone, or app, removing the need for traditional keys and allowing remote access management.

Are aluminium doors energy efficient?2025-12-11T21:57:39+00:00

Yes, modern aluminium doors are highly energy efficient. The key is the “thermal break” – a polyamide barrier inside the frame that separates the inner and outer aluminium, preventing heat loss. Combined with double or triple glazing filled with argon gas, our doors achieve excellent U-values (often as low as 0.8 W/m²K), meeting and exceeding current Building Regulations.

What are the main benefits of aluminium doors over uPVC or timber?2025-12-11T21:56:34+00:00

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.
