Overview
Alu-Gard is a 1.6 mm sheet of 5005 H34 aluminium alloy, perforated with 2 mm holes that leave 40% of the panel open, and powder coated. It is held in an extruded aluminium frame, either riveted or, in the Alu-Gard Edge version, with a PVC pressure retention system.
With no steel in the infill there is nothing to rust, which makes Alu-Gard a sound choice close to the coast. From inside, the perforations still give a clear view out.
Doors come with a 3-point lock.

Fantastic job by Knights Blinds & Security. The team turned up within a day of me requesting a quote which was excellent. The double sliding screen door looks great and slides perfectly. The four window screens all fit perfectly and look like they were original, they match the window colour perfectly. The installation team took away the old screens and left no trace. Delivery was approx 3 weeks after order which was reasonable.

Very happy overall. Price is good and product is good quality. I was having issue with the property and Knight security was very helpful. They hold back installation for a few months. Very much appreciate your help.
