Frequently asked questions

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 aluminium doors more expensive than uPVC?2025-12-11T22:00:47+00:00

The initial investment for aluminium doors is higher than for standard uPVC. However, they offer far greater longevity, a premium aesthetic, better performance, and require no maintenance costs (like repainting). Over their lifetime, they represent excellent value and can significantly enhance property value.

Can I have large sliding or bifold doors?2025-12-11T22:00:17+00:00

Yes. Aluminium’s strength makes it the ideal material for large-span openings. We can manufacture and install expansive sliding and bifold door systems with minimal supporting框架, creating breath-taking, seamless transitions to your garden or terrace.

Are aluminium doors noisy?2025-12-11T21:58:37+00:00

On the contrary, they provide excellent acoustic insulation. The robust, airtight seal and the use of double/triple glazing significantly reduce external noise pollution, creating a quieter, more peaceful indoor environment.

Do aluminium doors get cold in winter?2025-12-11T21:58:14+00:00

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.

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.

How long do aluminium doors typically last?2025-12-11T21:57:15+00:00

A high-quality aluminium door system, like those from Schüco, can last 40-45 years or more with minimal care. The aluminium itself does not degrade, and the powder-coated finishes are designed to withstand decades of UK weather without fading, peeling, or corroding.

Are aluminium doors suitable for period or traditional properties?2025-12-11T21:56:54+00:00

Absolutely. While known for modern designs, aluminium doors are incredibly versatile. We offer a range of classic colours (like heritage greens and greys) and even wood-effect finishes. The slim sightlines can be designed to complement traditional architecture, offering improved performance without compromising character.

What guarantee do you offer?2025-11-09T14:10:49+00:00

As we are the manufacturer and the installer, we offer a comprehensive, insurance-backed guarantee that covers both the product and the workmanship.

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 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.

Can I integrate smart locks or access systems?2025-07-11T14:45:57+01:00

Yes. Schüco doors can be equipped with biometric, keypad, or smartphone access systems for modern convenience.

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.

Are composite doors more expensive than uPVC doors?2025-09-18T20:52:43+01:00

While the initial investment for a composite door is higher than for a standard uPVC door, they offer significantly better performance, security, longevity, and aesthetics, representing far greater long-term value for your money.

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.

Can I get Schüco products in a colour to match my home?2025-10-10T15:51:42+01:00

Absolutely. Schüco offers an extensive colour palette for aluminium windows & doors products, including custom RAL colours for aluminium systems to perfectly match your vision.

Are they safe and secure?2025-11-09T14:08:47+00:00

Absolutely. All our glass is safety-toughened as standard. Our frames and locking systems are designed and tested for maximum strength and security.

How do you ensure the door fits my existing doorway?2025-09-21T14:54:57+01:00

Every door we provide is made-to-measure. Our process begins with a professional survey conducted by one of our experts. They will visit your home to take precise measurements of your existing opening and discuss all details on-site. This ensures your bespoke Crittall style door is manufactured to fit perfectly, eliminating any issues with irregular-sized openings.

Are Schüco windows expensive?2025-10-10T15:50:06+01:00

Schüco is a premium brand, and its price reflects its superior quality, performance, and longevity. While the initial outlay is higher than standard windows, they represent a long-term investment that adds significant value to your property, reduces energy costs, and enhances your quality of life.

Will a glass roof be too hot in summer and too cold in winter?2025-11-09T14:09:24+00:00

Not with modern technology. This was a common problem with old polycarbonate or basic glass. We use high-performance solar control and thermally efficient glass to ensure your room remains at a comfortable temperature all year round.

Are they more expensive than timber?2025-09-29T17:27:18+01:00

While the initial investment can be comparable to high-end timber, uPVC sash windows offer significant long-term savings. You will save thousands of pounds over their lifespan on maintenance, repainting, and energy bills.

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.

Are patio doors double glazed?2025-06-11T15:18:47+01:00

Sliding patio doors are usually made of two large glass panels, which open by sliding one panel behind the other. Sliding doors provide easy access to gardens and patios.

Are aluminium windows cold and prone to condensation?2025-10-08T22:58:56+01:00

This is a common misconception based on old technology. Modern Schüco aluminium windows feature a sophisticated ‘thermal break’ – a polyamide insulator that separates the inner and outer frames. This completely stops thermal transfer, making the frames warm to the touch and preventing internal condensation.

Will a conservatory be too hot in summer and too cold in winter?2025-11-09T15:38:58+00:00

Not if it’s designed and built correctly. Modern conservatories with energy-efficient double glazing, thermal breaks in the frames, and options like thermal roof systems or solar control glass are designed for year-round comfort. We can also integrate ventilation and blinds to perfectly manage the temperature.

What is the difference between a glass roof and a polycarbonate roof?2025-11-09T14:10:22+00:00

Glass offers far superior performance.

  • Clarity: Glass provides a crystal-clear view and lets in more light.
  • Longevity: Glass doesn’t discolour or turn brittle over time like plastic.
  • Acoustics: Glass is much quieter in rain.
  • Efficiency: Glass offers far better thermal insulation.
Are uPVC casement windows secure?2025-09-30T21:18:07+01:00

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.

Can I have trickle vents?2025-10-08T23:00:58+01:00

Yes. To meet building regulations and ensure adequate background ventilation, we can integrate almost invisible trickle vents into the window head.
