Windows and doors: High Security certification scheme

LPCB’s Window and Doors High Security scheme carried out to Loss Prevention Standard LPS 1175

Certification of your doors and windows under our high security scheme will assure your customers that they can rely on your products to provide the effective levels of anti-intruder security needed. All LPCB certificated products are immediately listed in the RedBook, a source used by specifiers and purchasers around the world when selecting security components.

Certification of products under LPCB’s Window and Doors High Security scheme involves assessing their resistance to intruders, which is carried out to Loss Prevention Standard LPS 1175: Requirements and testing procedures for the LPCB approval and listing of intruder resistant building components, strongpoints, security enclosures and free-standing barriers.

This standard comprises a range of manual intervention tests and can be applied to windows and doors manufactured from most commonly available materials. The certification process is summarised here [link to certification sub-page].

Grades 1 to 8 of security rating

The standard comprises eight grades of security rating (SR) defined by the array of tools likely to be used by intruders and the time available to them. LPS 1175 security rating 8 (SR8) represents the highest level of resistance to counter the highest level of risk. This grading system enables purchasers to select products and systems which provide the levels of security that match their requirements.

LPS 1175 / PAS 24*
LPS 1175 differs in a number of ways from PAS 24 (used in LPCB’s Residential security scheme ), notably in its approach to intruders that are willing to risk making noise in their attempts to enter a property.

PAS 24 considers resistance to opportunist criminals who wish to gain entry by stealth and without making noise that might attract attention. PAS 24 does not, for example, address breaking glass as an entry method. Products approved to PAS 24 are therefore best suited to domestic properties and others with either 24/7 occupancy or high volumes of personnel passing near the door/window concerned.

LPS 1175 evaluates a product’s resistance to forced entry by a wider range of intruders, including those unconcerned about making noise. Under LPS 1175, breaking glass is – as in the real world – recognised as a mode of entry for prospective thieves and is part of the assessment process.

LPS 1175 approved products are therefore well suited to scenarios where criminals can either work out of sight or where they are not fearful of being spotted. It is therefore a generally more secure standard than PAS 24, even at the lower security ratings.

*PAS 24: External doorsets and windows intended to offer a level of security suitable for dwellings and other buildings exposed to comparable risk and the specific.
