Composite Entrance Doors

Why Our Composite Doors?

Redkite Glass composite doors deliver uncompromised style and performance and come in a huge range of contemporary and classic designs. 

Featuring the ultra-secure Doorco GRP slab and the energy efficient Optima frame our composite door collection combines advanced thermal efficiency and leading edge security.

High Security

Local thickening in the Optima door frame and robust reinforcement further increases resistance to attack, while our composite doors also feature multi-point locking, the latest hardware and are supplied in a Secured by Design Specification as standard.

This includes a 3 Star British Kitemark TS007 anti-drill, anti-snap, bump resistant and anti-pick, SS312 Sold Secure Diamond Grade door cylinder.

The system is built around the high-performing Avantis door lock which features ultra-secure steel hook bolts and a steel compression deadbolt to deliver maximum strength to the centre of the door.
