RAL Window Colours 

NRG Glass have the facility to manufacture our aluminium products in any RAL colour, to your individual colour requirements. We use industry standard RAL colours, which are a range of over 200 colours available in gloss, semi-gloss and matt finishes, from approved coatings specialists. 
 
The Polyester powdercoat paint is baked onto the aluminium in order to withstand the rigors of all weather conditions and modern living in the UK. The high quality materials and process used means we can offer a 10 year guarantee on all painted aluminium, giving you peace of mind for years to come.
