How is a Rockdoor so much stronger than competitor doors?

All Rockdoors feature S-Glaze technology (Security Glazing) which is when the glass is manufactured as part of the door itself and locked in for life, rather than being clipped in by beads as an afterthought. This ensures exceptional thermal efficiency, but crucially it also means the glass can’t be forcibly removed by burglars as had happened to the neighbours.

Ultimate Rockdoors also feature Carbon Fibre reinforcement which strengthens the door even further, unlike other composite doors that are cut down and consequently weakened.

So whilst you may think a composite door is just that, there is actually much more to deciding which door should be the one to protect you and your family.
