The Passiv-line PLUS window won the Topten Okna 2014 competition. Our product was recognized by the jurors and was among the best windows in Poland.
The goal of the TOPTEN competition is to select 10 of the best, technically and economically, windows available on the Polish market. The competition was attended by producers and distributors of window and door joinery with technical properties confirmed by appropriate certification bodies.
Our Passiv-line PLUS window was appreciated by the jurors who took many factors into account. The parameters described by PN-EN 14351-1 A1: 2010 were assessed. The basis for the assessment was the joinery energy efficiency based on the energy balance. Other parameters describing the most crucial product features were also assessed: window heat transfer coefficient Uw, [W / m²K], solar energy transmittance coefficient gG, light transmittance coefficient Lt, glass color rendering index – Ra, wind load resistance class, water tightness, acoustic insulation of the RW (C; Ctr) window, aesthetics and functionality of solutions and installation, details of which are described in the product warranty card. The products were subjected to a comparative assessment concerning windows meeting the current legal requirements (reference windows).
