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.

We’re proud to use both Planitherm Glass and Pilkington Glass and Astral is a member of the Planitherm installer network.

Astral is delighted to offer free upgrades from double to triple glazed units at no additional charge. To see why you should consider triple glazed products click here
