Specialist patio door manufacturer, Sliders UK, has been awarded Secured by Design (SBD) ‘Police Preferred Specification’ status for its Ultimate High Security range of bi-folding doors. Sliders’ Ultimate PVCu/aluminium composite system is the first and only bi-fold to achieve the much sought after Police security accolade, confirming its position as the most secure and crime resistant bi-folding door in the UK.

Sliders’ achievement marks an important milestone in bi-fold development. Although bi- folding doors have become an increasingly popular style choice in recent years, the low quality of the locking hardware used on some products has been criticised for failing to protect properties and occupants from would-be intruders.

Gary Fisher, Senior Development Officer at

ACPO SBD comments: “We are delighted that a bi-folding door has achieved the standards required for Secured By Design. It proves that when a manufacturer invests time and money into developing new security features, it’s possible to develop a product that is more resistant to criminal attack. Indeed, research has consistently shown that developments incorporating an SBD-approved specification are half as likely to be burgled, and are at a 25% lesser risk of criminal damage.1”

Sliders’ Ultimate High Security bi-folds are the only bi-folding doors to be awarded SBD status, which means that they have been specifically

upgraded and tested to meet the security standards identified by the Association of Chief Police Officers Secured By Design (ACPO SBD) initiative. Sliders’ Ultimate bi-folding doors incorporate a variety of enhanced security features, including a uniquely designed, PAS 24 approved hook locking system; kite-marked anti-snap/anti- bump cylinders; secure, low level keep plates; and a strong aluminium sub-frame with quadruple seals on all sash joints.

Ian Longbottom, Director of Sliders UK, comments: “We have put a lot into achieving Secured by Design status for our bi-folding doors, and are delighted that ours is the first to meet the Police Preferred Specification. Secured by Design is a highly credible initiative and we are confident that installers and specifiers will reap the benefits of our newly approved bi-folds thanks to the added assurance and peace of mind they can now offer to customers and homeowners.”

In addition to security, Sliders have added a

number of other features to the Ultimate bi- folding door to improve the all round performance and maintenance of the system. These include a new running track which is located on the floor to better support the weight of the system, and the addition of a brush seal on the outer track to prevent fallen leaves and other debris from accumulating in the ‘running area’.

To deliver improved aesthetics for property owners, the threshold height has also been


Liniar’s innovative Bi-Fold Plus has the best design of any PVC-U bi-fold door on the market, according to Green Energy Windows. And as a result sales are growing.

Ravi Hanjhra, Managing Director of the fabrication and installation company, says the complete bi-fold system is far more fabricator friendly too.

He says: “Old style PVC-U bi-fold doors were difficult to produce. But because Bi-Fold Plus is a simple system it makes fabrication much easier. ‘There is one sash profile and the outer frame is the same whether the doors open inside or outside. It’s even easier to fabricate than our aluminium bi- fold door.

“We chose to add Bi-Fold Plus to our range because it is the best design on the market and is similar to the aluminium bi-folds we sell. The slimmer sightlines mean there is more glass and it’s much more attractive to consumers. We’ve been actively marketing Bi-Fold Plus and sales are going well. We’ve had nothing but positive feedback.”

massively reduced. Standing at 106mm, the threshold on Sliders’ Ultimate bi-folds can also be sunk to achieve as low as 66mm threshold height, compared to the much higher threshold height (typically 144mm) offered by most other PVC bi-folds.
