Quality Tested Products and Services
The key to knowing that we offer a quality product and service is to let them be independently assessed. We applied this theory to our draught-proofing system, the Ventrolla Perimeter Sealing System (VPSS), which was put through intensive independent testing to British Standards. The result proved the system improves energy efficiency, without altering the appearance of the window. VPSS ensures all of the gaps around the sashes are filled, creating a fully sealed sash window or casement window. Furthermore, due to the low friction levels of the sealing system, the sliding operation of a sash window is restored to full working order. The VPSS has been independently tested and its benefits verified by the British Board of Agrément and Acoustic Consultants Hann Tucker.
The Statistics that give true peace of mind:
- VPSS is manufactured to British Standards (BS) 7386:1900 and is tested to British Standards 6375:1-2009; one of the most demanding European Quality Standards
- VPSS exceeded Class 3, the highest level of 600Pa, which is the equivalent to 71 mph winds
- VPSS has been independently proven to improve the Window Energy Rating (WER) by up to 30%
