Choose your colour
Astral has the facility to provide aluminium products in any RAL colour, including dual-colours (different colours inside and outside).
The polyester powdercoat paint is baked onto the aluminium in order to create a durable, tough finish that can withstand all weather conditions. The high-quality materials and process allow us to offer a 10-year guarantee on all painted aluminium.
Glass and decorative finishes
While the quality of your windows has a big effect on your energy bills, design influences the ‘kerb appeal’ of your home. Astral has proven pedigree when it comes to advising customers at the planning stage, thus ensuring a glazing solution with a positive impact on both.
