Rockdoor has been the driving force behind composite door technology for over 20 years.

During that time, more than half a million doors have been produced at our Lancashire innovation and production centre.
We use nickel-coated solid brass for our hook locks, high impact uPVC skins to resist cut-through, carbon fibre to reinforce our inner frames and a unique S-Glaze system that locks the glass into your door for life. It means Rockdoors can’t be forced open.
And because every Rockdoor is made-to-measure rather than mass-produced to a standard shape before being trimmed to size, it’s an exact fit for your home. It means no leaks, no draughts and lower heating bills.

The toughest, safest and most energy efficient door. Keeping you safe. Reducing your bills. Giving you choice.
