Innovation in security door manufacturing has resulted in enhanced physical security and far greater choice particularly in relation to design. Suitable for almost any public building application, security doors are now being fitted in schools, hospitals, embassies, leisure centres, museums and even places of worship.
All security doors comply with the current European burglary resistant standard ENV1627, which concentrates on resistance to forced entry. Customers in the market for security doors may well come across products bearing an additional certification, PAS 24. Security door sets meeting this standard have undergone rigorous testing and resisted attacks each lasting up to 15 minutes from a variety of handtools such as hammers, crowbars, chisels, hacksaws and some power tools.
Additionally, security doors can be manufactured to meet standards for thermal and acoustic performance, fire protection and weather proofing (wind, air and water sealing). Further highly specialised security door sets – for example, to meet anti-ballistic criteria – can also be produced.
An experienced burglar can force open a door fitted with just a single mortise lock in a matter of seconds. To protect against this risk, security door sets have a high security multi-point locking system which double locks the door into the frame at a number of different points.
Instead of having to use two or three keys to engage different locks at different heights on the door leaf, a single key operates one cylinder to activate the locking bolts at the top, bottom and centre of the locking side of the door. This offers a significant advantage of quick, easy access without having to carry a collection of keys to unlock a single door.
Furthermore, the European profile safety cylinder – widely used in security door manufacturing – has a ”defender” of tempered drill-proof steel to afford maximum protection against manipulation and extraction.
As well as mechanical locks, a sophisticated motorised multi-point locking system is also available. This can be connected to a wide variety of access control systems or connected to a centralised control system operating a variety of electronic systems in a building.
In recent years manufacturers have rebutted the popular misconception that security doors are ugly and unattractive by introducing an extensive range of modern and traditional designs. No longer just unsightly, forbidding steel barriers to deter criminals, security doors are now manufactured with a diverse range of attractive designs and finishes both to increase security and also contribute to the building’s overall design. From classical to contemporary, the choice available is extensive and will suit individual tastes and different architectural styles. And it’s worth noting, security door sets are routinely manufactured to meet the stringent requirements imposed by conservation and planning officers for listed buildings.
Simple but sophisticated designs of unadorned solid wood panels made from oak, cherry, Italian walnut, mahogany and pine remain popular. For more decorative styles there are wooden doors in a range of patterned finishes that can even feature different woods combined to create stunning designs with contrasting grains.
High quality door sets can also have patterned, RAL painted or engineered wood finishes. These can be combined with solid wood mouldings to suit most architectural and decorative styles.
Top of the range aluminium panels featuring original geometric patterns represent the very latest in contemporary design. Available in plain aluminium or in RAL colours, they are an ideal choice for specifiers looking for a modern security door solution without compromising on strength and durability.
Glazed security doors are also available. Using laminated safety glass with a thickness to 31mm and conforming to the European standard for security glazing EN356, doors can be supplied with side panels (glazed or solid panels) and overhead fanlights. Further variations include double doors (including “leaf and a half”) and arched doors (single and double).
Additionally, in general environmental terms, the majority of security door sets offer significant advantages in terms of thermal and sound insulation.
While a security door’s principal function is to prevent criminals gaining access by forcing a main door, by placing greater emphasis on design, security door manufacturers are now achieving this far more aesthetically.
