Test success

Kömmerling’s PremiLine PRO patio door has achieved PAS 24 in a four-pane variant, using a single door set for the entire testing procedure and without the need for additional plunge bolts.

PremiLine PRO was originally launched in August 2015 and was claimed to be the first PVCU patio door that could achieve PAS 24. It could also meet the standards for operational handle height of no more than 1,200mm from the floor within the Lifetime Homes design criteria.

The PAS 24 procedure involved a 15-minute test with human intervention of crowbars and other hand tools, followed by the mechanical loading of 37 different points on the door, which were subjected to half and quarter tonne loads in different directions.

Additional human intervention, along with soft and hard body impact testing was all carried out on the same door, from the start to the conclusion of the testing programme.

PremiLine PRO, in this four-pane variant, came through the PAS 24 testing with ease and will carry Secured by Design certification, which will also be extended to three-pane alternatives and a triple track design.

The PremiLine PRO concept was developed in conjunction with Fullex Locks, by harnessing a compact sized multi-point locking system at the patio door interlock, which is operated by a simple lever. It was launched in response to the new Document Q regulations and will offer housebuilders a compliant, German-engineered door that looks and performs to the latest standards.
