COR 70 HV Windows might have fewer opening possibilities than some of the other products available at Grabex, but they're definitely practical, especially when it comes to means of ventilation or ease of cleaning and maintenance.

The windows are inward opening only, and can be side hung, tilt and turn, or tilt only.



Aluminium frames can be polyester-powder coated in a wide range of RAL colours, or come in a wide range of other finishes including an anodised finish - for that metallic option, woodgrain - to perfectly imitate the natural look of timber, and event come as anti-bacterial powder coatings.

Our standard range of RAL colours covers some of the most popular customer choices for achieving that premium look. Though if you're looking for something different choose from a wade variety of RAL palette options and finishes.

For something a little bit different - choose textured coatex finish, or dual colour, where you can have different colour on the inside than on the outside!
