Overview
Colonial doors swap a plain mesh for a decorative cast pattern, and suit period and character homes. They are hinged barrier doors, made to measure for the doorway.
They are gravity die-cast from recyclable aluminium, which does not rust, then powder coated in your choice of colour.
Behind the pattern you choose flyscreen, tough mesh or DVA one-way mesh, and a triple lock secures the door.
Sidelights and screens
Matching sidelight panels cover the narrow glass beside the door, an often-overlooked weak point. Windows can be fitted with Invisi-Gard or our other screen ranges for a consistent finish.

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.
