Glass News talks to DOORCO MD, Dan Sullivan, about FLiP – DOORCO’s own revolutionary cassette system and the latest innovation for the market from the leading composite door supplier.


Contemporary homes reflect the architecture of today. Even in renovation, there is a massive shift in demand towards clean lines and stark minimalism. The industry as a whole endorses this fashion in their product offering. For example, aluminium is now mainstream; nearly all system houses offer their own system and fabricators supply it on the same basis as PVC-U.

When it comes to doors, the trend quickly escalated from choosing Anthracite over Black to get “the look”. DOORCO pioneered the contemporary GRP composite door with the launch of Monza (linear 8-panel design and unique book-matched woodgrain detail) back in 2014 and Links (the aluminium-replica GRP composite door) in 2017. Both have evolved beyond contemporary, with designer-led unique colours and styles, with a world of other possibilities. What has been restricting this opportunity, however, is the lack of complementary glazing options. Others have tried to solve this issue, but no new designs have been launched that have anywhere near the same qualities as the current best-selling traditional system. Plus, there’s reluctance from incumbent cassette manufacturers to make any substantial development investment.


DOORCO is committed to innovation. Pairing this with our independently owned status, we are in charge of our own destiny. We felt it was time to address the glazing cassette problem and enable our customers the opportunity to take contemporary door design to the next level. Working with innovative UK based designers and drawing on the DOORCO team’s experience and knowledge of the sector, we set about creating our own glazing cassette system. A considered and conscientious development process has resulted in FLiP, our revolutionary range of door glazing cassettes that are more flexible, more practical and aesthetically pleasing.



FLiP has a unique Foam in Place technology that delivers a superior seal and aesthetic freedom never seen before. We’ve developed a system that is simple to install and has three styles to suit any type of home. There are clean, modern profiles through to traditional bevels, all with a low profile to fit nicely with the overall design of the door, so you can be:

FLiP’s Through Colour Technology ensures a perfect match to the standard DOORCO colour range, making it the perfect partner for our doors. Or if you are looking for something bespoke, your choice of cassette and door can be painted together using our bespoke colour service.



As well as style, one of the most important factors in making FLiP succeed is simplicity. We’ve developed a system that has consistent components throughout, regardless of style. The cassette is installed with a simple click-together mechanism that requires minimal use of tools.  In fact, all you are likely to need is a screwdriver! The revolutionary Foam in Place technology offers pre-sealed outer frames with structural connectors that are flexible to use with 24-26mm glass units, and a unique tilting head that adjusts to the thickness of the glass. The innovative angled corner protector adds reduces corner flare and supports heavy units, with an optional component to insert in larger apertures offering additional security if needed. The system is fully re-glazeable.

FLiP has undergone extensive testing to ensure it is weatherproof and secure. Doorsets containing the system have been tested to BS6375-2015 and in accordance to EN1027. Furthermore, they achieved over 1000pa through the glazing aperture during weather testing. This is further supported by DOORCO’s 10-year warranty on FLiP.

FLiP is available now from DOORCO and is being launched initially in familiar shapes and sizes to suit our current range of door designs. But, for DOORCO to have our own cassette system is an exciting advancement that opens up endless possibilities. Our doors are a canvas that is versatile and comes in all shapes and sizes. We now have the opportunity to explore how we can really take door design – contemporary, traditional and beyond – to the next level.  We have gained greater control of the supply chain too. By focusing on offering the complete composite door package and having the product made in the UK, we are able to offer better guarantees to customers.
