Frequently Asked Questions

We have answered some of the most common questions about our aluminium doors, giving you the essential information to make confident choices for your project.

Are aluminium doors better than uPVC?

For most homeowners seeking slim sightlines, larger glazed areas and long-term stability, aluminium is the stronger choice. Modern thermally broken aluminium doors deliver excellent energy performance, will not warp or discolour over time, and can be powder coated in any RAL colour. uPVC can sit at a lower price point, but aluminium wins on strength, design flexibility and lifespan.

Are aluminium doors energy efficient?

Yes. Our aluminium doors use a polyamide thermal break together with high specification glazing to limit heat loss and keep internal frame surfaces warmer. This helps maintain a comfortable home year round and supports compliance with current Building Regulations

What types of aluminium doors do you offer?

Our range covers external doors and screens for connecting living spaces to the outdoors, internal doors and screens for dividing rooms while keeping light flowing, and heritage aluminium doors that echo the slim proportions of traditional steel. Configurations include single, double, French and sliding styles to suit the opening.

Can I match my aluminium doors to my windows?

Absolutely. The aluminium door and window ranges share frame finishes, hardware options and the full RAL colour palette, so you can create a consistent look across the whole property. Many of our clients pair heritage aluminium doors with matching windows for a unified result.

Are aluminium doors secure?

Yes. Our aluminium doors are built with robust frames and high quality multi point locking, giving you reliable security alongside their refined appearance. Hardware finishes can be selected to complement the overall design.

How do I maintain aluminium doors?

Aluminium doors need very little upkeep. An occasional wipe with warm soapy water keeps the powder coated finish looking its best, and the frames will not rot, warp or fade, ensuring long lasting performance with minimal effort.
