Life Cycle Performance

Janex provides true life cycle analysis for its products:

Windows and doors need to perform a number of functions in their service life. In some applications they may need to be fire resistant, as well as working effectively as a means of providing access/egress and ventilation. In public buildings for example, doors and windows are used more frequently and subject or more physical abuse than in other applications, it is therefore vital that these doors and windows are durable so that they will be able to continue to perform their every day function and maintain specified functions.

Janex product portfolio has the best possible components to meet the highest demands of windows and doors for all applications and the purpose they are used for. Each component is chosen for its performance and reliability. Certification, test results and guarantees also form part of the selection criteria.

Janex windows and door-sets have been put through vigorous testing against a range of British and European test methods to prove the durability and performance at UKAS testing station, TRADA Chiltern Dynamics and Chilton Fire.

Test programmes have been developed to establish the service life of windows and doors to demonstrate the performance capabilities of the Janex products. TRADA have carried out an extensive review of UK and European codes and testing standards, selecting the toughest tests to develop the service life testing programme.

Durability testing considers a number of factors:

  • Cyclic operation – opening and closing
  • Strength – slamming, heavy body impact, hard body impact, torsion, downward deformation, closure against obstruction, resistance to jamming, vibration, abusive forces on handles
  • Dimensional requirements
  • Dimensional stability

For heavy duty applications
Testing has been carried out on products that have a high frequency of uses with the likelihood of accidental damage

For Severe duty
Test applications where the products are subject to violent use.

Slamming shut impact
Doors tested to withstand being slammed shut by someone passing through it, from gusts of wind or a door closer.

Thrown open impact
Similar testing for opening – product is tested withstand being thrown open.

Heavy body impact
Product tested for impact resistance, whether from a human being or any other object. For glazed doors the test is limited to those patterns which have at least a middle rail. All glazing complies with BS6262

Hard body impact
product tested for its ability to resist impact from hard objects, such as the corners of furniture, cleaning equipment small trolleys or footwear, the requirements of this part of the test covers both strength and the appearance of the product after impact. Where there is a need for exceptional resistance to impact it may be necessary to specify special fittings for example kick plates or bars.

Tension
door is tested for its ability to withstand forces that result in tension to its face. If a door sticks, the force that might reasonably be expected to be applied in attempts to free it should not cause failure.

Downward deformation
Door is tested for its ability to resist downward forces, such as a child swinging on the handle.

Closure against obstruction
Product is tested for its ability to withstand the effects of closure against an obstruction. Small objects that might jam between the window/door and frame in the hinge side might make it jam

Resistance to jarring and vibration
Doors including fixing for hardware should be capable of resisting jarring and vibration caused by impacts form persons or heavy objects passing through a partly opened doorway

Abusive forces on door handles
Product is tested for resistance to force applied to the handles. Abusive force (other than vandalism) that might be applied to a door handle in robust use should not damage the door.
