We are 100% confident in the tightness and high quality of the COMBI threshold technology. This is confirmed by professional tests and certificates from Rosenheim. The well-designed construction, compatibility with specific PVC or timber window-door profile systems, and installation support ensure that we offer customers a solution tailored precisely to their needs.
This was confirmed by the company PARTNER-ALMA from Limanowa, which tested a double-leaf window construction with a floating mullion in the Aluplast 8000 system using the COMBI threshold system, achieving a tightness result higher than that declared in the official certificates (8A) – as high as 9A (600 Pa).
The test was carried out in a mobile chamber at the manufacturer’s premises, and the professional installation of the thresholds was supported by our technical consultant.
The company PARTNER-ALMA is currently awaiting the full documentation and test certificate. We hope that the analysis will confirm the achieved parameter. At Alumaster Polska, we are pleased that our customers experience exactly what we are confident about.
Jointly conducted tests not only:
- strengthen our cooperation,
- but also: ensure excellent results,
- confirm the importance of proper installation and matching the threshold technology to the window and door construction.
