XtremeDoor, the new high performance composite door, from Vista was recently put through a trio of rigorous tests to see how weather resistant, thermally efficient and secure it really is – and passed all three with flying colours.
The assessment test for weather tightness was carried out at Winkhaus Laboratories on XtremeDoor Glazing system and was terminated after XtremeDoor withstood 2000 Pascals. A pascal is a unit of pressure, equal to one newton per square metre (N/m2). To put this figure into perspective, 670 Pascals equates to a Hurricane (which is a wind speed of 75mph) – and XtremeDoor exceeded this by a factor of three.
This followed on from a thermal performance test that concluded XtremeDoor is 19% more thermally efficient than the solid timber core composite door and 17% more thermally efficient than the traditional timber panelled door.
In this test the University of Salford took a composite door manufactured with a 44.5mm Nan Ya composite door slab, which is a key component in XtremeDoor, and pitted it against a 48mm solid timber core composite door and 44mm timber panelled door.
The doors were tested in a typical 1919 terraced house that had been reconstructed in a fully environmentally controllable chamber, in which climatic conditions can be maintained, varied, repeated and patterns monitored. For the test, the inside temperature of the Energy House was 25°C with an exterior temperature of 5°C.
The Nan Ya composite door
After extensive testing the Nan Ya composite door was found to be 19% more thermally efficient than the solid timber core composite door and 17% more thermally efficient than the traditional timber panelled door.
Finally the doors security was put to the test by Greater Manchester police. A member of the police riot squad battered the door for an extensive period but thanks to XtremeDoor’s five point lock he was unable to gain entry.
Vista’s managing director Keith Sadler commented: “XtremeDoor was built to withstand extreme weather conditions, offer superior thermal performance and protect from intruders and it doesn’t surprise me that the door exceeded all tests with room to spare. XtremeDoor is manufactured using the foam filled Nan Ya slab. Foam is an excellent insulator, after-all it is the material what you would use to insulate the walls in your house, so it has a major thermal advantage over a solid timber core composite door and a timber panelled door.
“XtremeDoor also has a triple sealed outerframe for superior weather performance and a five point lock with anti-bump, snap and drill cylinders for ultimate security. Installers can use these test results to prove to homeowners that XtremeDoor is a premium product and will offer superior protection for their home, helping them command better margins.”
