Dessian Permaglide at Enviro

The fantastic Permaglide range of aluminium doors solves the one problem that aluminium doors have. Aluminium is a brilliant building material as it’s lightweight, has a low profile, is very strong and resists corrosion but it is a good conductor of heat and as a result can let out heat, resulting in higher heat loss than uPVC.

Dessian’s full-width thermal core maximises the use of low conductive material and work brilliantly at keeping out the cold. You get the sleek look of aluminium along with outstanding energy efficiency. Permaglide doors are available with either double or triple glazing too.

The aluminium frame is incredibly strong and secure and the doors (or sashes) can be made in many different combinations. You can specify any opening door combination you like. The doors can be stacked open to one side or split and stacked to both sides. You can even have one panel opening like a conventional door or two panels opening like French doors. Most people like to have a single opening door (a traffic door) that they use regularly as a standard door allowing them to leave the opening sashes in place until they want the entire door opened up.

Incredibly stylish and flexible, our Permaglide range features include:

• Aluminium construction, very low maintenance, no painting, no warping, so shrinking
• High-security locking system with full Secure by Design certification
• The option of inward and outward opening doors
• Extremely efficient with high-performance glass fitted as standard
• Low thresholds for easy access and low profile for minimum frame size and maximum glass area
