Composite Doors

Composite doors are the toughest, safest and most energy efficient doors, keeping you safe and reducing your energy bills.

They can’t be forced open and because every door 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.


Our composite doors use nickel-coated solid brass for hook locks, high impact uPVC skins to resist cut-through, carbon fibre to reinforce inner frames and a unique S-Glaze system that locks the glass into your door for life.

Main Features
  • Hook Locks – Nickel-coated solid brass. They slide into steel keeps that run the full length of the outer frame. It means your door can’t be forced open.
  • Carbon Fibre – Used to build Formula 1 racing cars, orbiting satellites and fighter jets. Used for door reinforcement it’s guaranteed to withstand phenomenal force.
  • High Impact Skins – 50mm sash and high density core resists cut-through.
  • S-Glaze – The unique system that locks the glass into your door for life. No leaks. No draughts. No burglars.
  • Made to Measure – Every door is designed and built from scratch to be an exact fit.
  • 3 Star Cylinder – Master Locksmith Association’s highest possible rating – SS312 Sold Secure Diamond status.
  • Engineered – Doors are designed and engineered to keep you secure in your home.

A combination of material choices such as PVC-U and a 50mm thick high density polyurethane core, and unique manufacturing techniques such as S-Glaze Technology make Rockdoor the envy of door manufacturers across the land.
