ALUMINIUM WINDOWS & DOORS FAQS
Frequently Asked Questions
Explore our FAQs for helpful advice on aluminium windows and doors, from energy efficiency and security to customisation and installation with Richard Thomas.
Are aluminium frames energy efficient?
Yes. Today’s aluminium systems use thermal break technology to prevent heat loss, and many meet A or A+ energy ratings.
Do I have to go with grey or black frames?
Not at all. While Anthracite Grey is popular, you can choose from hundreds of colours – including dual-colour frames with different finishes inside and out.
Are these systems suitable for coastal homes like those in Dorset?
Absolutely. Aluminium is corrosion-resistant and particularly well-suited to coastal environments – especially when powder-coated to marine-grade standards.
Is aluminium a good option for period homes?
Yes – especially with systems like AluK’s Heritage range or Smart’s Flush Casements. These replicate traditional timber or steel styles with all the benefits of modern performance.
