INTENSE TESTING

The Secured by Design testing process is intense and comprehensive, comprising:

  • A manual attack on the locking hardware with tools including a crowbar and mole grips.
  • An unlimited number of 3-minute attacks on the door cylinder using a range of tools such as craft knives and screwdrivers.
  • 3-minute manual attack using chisels and brick bolsters to gain entry through the door.
  • Hard body impact test – impacts are applied to the door leaf at hinge points and locking points using a 50kg steel impactor.

Utilising high-impact modified materials and GRP skins that resist weather and physical force.

Technical FAQ

Contact our Bordon headquarters on 0345 470 1977 for specific technical enquiries regarding your composite door installation.

Composite doors utilise a combination of materials including glass reinforced plastic (GRP), rigid polymers, and timber cores. This results in a thicker (44mm to 48mm) door that offers significantly higher thermal insulation and security compared to standard uPVC panels.

Yes. All three suppliers provide systems that meet the Secured by Design (Police Preferred Specification). They feature multi-point locking mechanisms, anti-snap cylinders, and high-impact skins as standard.

We provide a full turnkey service. This includes technical surveys, architectural visualisation, structural building works (if widening an opening), and building control management across Hampshire and Surrey.
