Aluminium Door FAQs
Are aluminium doors better than uPVC or timber?
Yes — aluminium doors offer far superior strength, slimmer sightlines, and greater design flexibility than uPVC or timber alternatives.
They last over 40 years, resist warping and fading, and are fully recyclable.
uPVC remains cheaper initially, but aluminium provides a much longer lifespan and lower maintenance over time.
How much do aluminium doors cost?
Aluminium door prices depend on several factors:
- Size and number of panels
- Type (bifold, sliding, French, or entrance)
- Glazing specification (double, triple, acoustic or solar-control glass)
- Colour/finish (standard RAL vs textured or anodised)
- Site access and installation complexity

How energy efficient are aluminium doors?
Very efficient.
Our thermally broken aluminium frames achieve U-values as low as 1.2 W/m²K, with argon-filled glazing and warm-edge spacers.
All systems comply with Building Regulations Part L for energy performance.
Are aluminium doors secure?
Absolutely. All systems can be manufactured to PAS 24 and Secured by Design standards.
Every door includes:
-
Multi-point locking

Anti-snap cylinders
-
Reinforced frames and hinges
-
Toughened or laminated safety glass

Can aluminium doors meet Building Regulations?
All our systems comply with BS EN 14351-1 and Building Regulations Part L.
How long do aluminium doors last?
Typically 40–50 years with minimal maintenance.
The powder-coated finish is baked on for long-term colour stability and weather resistance.
Can you match my existing colour?
Are aluminium doors suitable for safety-critical areas?
Standard aluminium doors provide excellent strength and durability but are not automatically fire-rated.
We can supply fire-rated or smoke-control aluminium systems on request, tested to BS 476-22 / EN 1634-1 where applicable.
Always specify your fire and safety requirements during quotation so we can recommend the right system.
Do aluminium doors reduce noise?
Yes — when fitted with acoustic laminated glass, aluminium doors can reduce external noise by up to 45 dB Rw, making them ideal for properties near roads, railways or airports.
What maintenance is required?
Clean frames twice yearly with mild detergent and water.
Lubricate hinges and locking mechanisms annually.
Avoid abrasive cleaners and always keep drainage holes clear for optimum performance.
Do aluminium doors require special cleaning products?
No — just a non-alkaline, non-abrasive household detergent and a soft cloth.
For coastal properties, rinse with fresh water more frequently to remove salt deposits.
Are aluminium doors suitable for coastal environments?
Yes — aluminium is corrosion-resistant and, with marine-grade powder coating, ideal for coastal or high-exposure sites.
We use Qualicoat-approved coatings for superior durability in these conditions.
Do you offer commercial aluminium doors?
Yes — we manufacture and install commercial aluminium doors for shops, schools, offices and showrooms.
Our systems include Comar 7P.i Commercial Entrances and Smart Shopline ranges for heavy-traffic use.
We only use high-quality products in our installations. All our systems comply with BS EN 14351-1 and Building Regulations Part L
