HI Q HIGH SECURITY DOORS
Bespoke steel-reinforced security doors.
Residential finish. Serious protection.
Our high security doors look like beautiful front doors — but inside, they’re built like engineered systems. Reinforced steel cores, four-direction multi-point locking, anti-drill protection and optional ballistic upgrades. Made in Britain and installed by HI Q WINDOWS.

Security first
Not just a stronger door. A full security system.
A high security door is more than a thick slab. It’s a full system: reinforced leaf, high-grade hinges, anti-drill cylinders, multi-point locking in multiple directions, and a steel frame that’s fixed back into the property. That stops the most common break-in tactic: attacking the frame.
  • 4-direction multi-point locking engagement
  • Drill-resistant lock protection plates
  • Reinforced steel frame anchored to masonry
  • Anti-jemmy hinge and keep design

Comfort
Security without living like you’re in a bunker.
Our high security doors are insulated with dense cores and high-performance layers. That means better thermal performance and better noise reduction than old timber or hollow uPVC panels. Warmer hallway. Quieter lounge. Less draught under the door.
  • Multi-layer insulation in the door leaf for heat and sound control
  • Compression seals and drop-down thresholds to fight draughts
  • Optional fire-rated and acoustic-rated specifications

Design
We match your look — period, modern or completely bespoke.
You don’t have to “look secure.” We can build traditional panel detail for Victorian terraces, heritage lines for conservation-style frontage, or ultra-modern flush slabs with minimal sightlines. We can even replicate the door you already love — but engineer it with internal steel and modern locking.
  • Any colour, matte or textured
  • Woodgrain, cottage, or minimalist flush styles
  • Custom handles, knockers, escutcheons and letterplates
  • Side panels and toplights available to suit your opening

Which level do I need?
We’ll recommend the right spec based on where the door is going — family home, apartment, business entrance, panic / safe room, or high-risk / high-profile property.
