    Security

    As well as optional advanced laminated glass or triple glazing, and one of the most secure door locks included as standard (Residor), all of our GRP composite products undergo extensive testing and checks. This means they can achieve the sought-after PAS 24 Enhanced Security Performance status, for peace of mind they can resist physical attacks by opportunist burglars.
