The DOORCO slab can be customised in a variety of different colours, letting your customers choose a door that fits in with their tastes. The composite door is available in 8 standard colours, 38 premium colours and in any RAL colour.


The ODL Europe TriSYS 3-piece glazing system is an excellent addition to this composite door. As this is a dry glazed system, the outer frame and inner cassette are screwed together, holding the door into place and snap on the inner frame. Should the glass in the door break, it's simple to take the cover off, unscrew, put new glass in and put it back on the door.


Optional door furniture, such as letterboxes, are available in our composite doors, coming in a variety of different colours.


Handles are another piece of door furniture available. Secured by Design and PAS24:2012 compliant as standard, your customers can choose from a variety of different colours.

Smart as Standard

These doors are fitted with the Kubu Smart Hardware as standard, bringing the security of your customers homes into the 21st-century.

The smart sensors check the status of the door in real-time and can be checked from any place. With every turn of the key in the lock, your customers will get notifications. As soon as they disconnect from the wi-fi, perimeter notifications will activate, sending them a notification if the door is unlocked.

Scheduled notifications can be set to ensure your customer’s don’t go to bed without locking the door.

The door can be shared with up to 4 people, meaning a whole family can check the lock status or those looking after the property.

It’s not just the app where you can check the lock status, with customers receiving a visual indicator that plugs into the home. The indicator glows blue when the door is locked or glows orange if at least one is unlocked.

You don’t have to offer your customers Kubu smart hardware and is available with various installation & integration options.
