Superb steel windows with anti-terrorism levels of security

Premier Security & Fire offers residential clients and building professionals a choice of high-quality steel windows, doors and screens, tailor-made to your specific requirements. We are also offering levels of security not previously seen in the UK market.

Premier is taking home security to previously unheard levels with a range home designs equal to counter-terrorism standard. Our designs are varied, bespoke and include Crittall style installations.

Our steel, double and triple glazed windows and doors will withstand a minimum 10-minute sledgehammer attack, and a whole lot more. This can be upgraded to ballistic resistance up to AK47 automatic weapons level (E-10).

Premier is partnering Swedish glazing experts Hammerglass with designs that combine aesthetic style with the highest level of safety. Hammerglass is 300 times stronger than standard glass as is half the weight.

Premier has 30 years of experience designing and manufacturing high-security doors and windows primarily for the professional and government sector. Our security installations have been produced for embassy buildings in London, prestige office projects in Canary Wharf as well as local council housing contracts throughout the country.

We provide a complete service – from the provision of technical drawings through to manufacture, installation and after sales support.
