What are the differences between PVCu and aluminium doors?

Both will suit different property styles and project needs. PVCu doors can be manufactured to mimic the appearance of traditional timber doors and are available in various colours and finishes while aluminium doors have a sleek and modern look and can be powder-coated in different colours. Ultimately, the choice between PVCu and aluminium doors depends on your specific requirements. Consider factors such as durability, maintenance and thermal efficiency.

What are the advantages of getting my doors from a single supplier?

You don’t have to source from different suppliers, which can cause a problem when it comes to delivery. Dealing with a single supplier like Sterling means you get consistent service and technical help and expertise. We supply doors that cater for any solution, meaning we can simplify your supply chain.

How easy are the doors to install?

We know how important it is to reduce fitting time, both for our customers so they can maximise their time, and for the end user so jobs can be completed in the timescale agreed. That’s why our range of PVCu and aluminium doors is easy to install.

What are the lead times on doors?

We provide two-week lead times on our doors to Warrington and beyond thanks to 24-hour manufacturing, helping us to supply high-quality doors that you don’t have to wait for at competitive prices.
